SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
The Legend Coupe Supplemental Restraint System (SRS) includes a driver's airbag, located in the steering wheel
hub, a front passenger's airbag, located i in the dashboard above the glove box, and seat belt pretensioners, located
in the seat belt retractors.
Information necessary to safely service the SRS is included in the ‘93 Legend Coupe Shop Manual Supplement
(62SP121). Items marked with an asterisk (+) on the contents page include, or are located near, SRS components.
Servicing, disassembling or replacing these items will require special precautions and tools, and should therefore
be done only by an authorized Honda dealer.
A WARNING
e To avoid rendering the SRS inoperative, which could lead to personal injury or death in the event of a severe
frontal collision, all SRS testing and repair must be done by an authorized Honda dealer.
® Improper procedures, including incorrect removal and installation of the SRS components, could lead to per-
sonal injury caused by unintentional activation of the airbags and seat belt pretensioners.
® All SRS electrical wiring harnesses are covered with yellow outer insulation. Related components are located
in the steering column, center console and armrest, dashboard lower panel, and in the dashboard above the
glove box. Do not use electrical test equipment on these circuits.

Role of System
The traction control is a variable system designed to enhance traction during acceleration and cornering. It does so by
determining the optimum amount of wheel spin for any given driving situation, then suppressing surplus engine power
accordingly.
Construction and Function
The TCS control unit gets signals about the vehicle's speed, direction and road conditions from the wheel sensors, steer-
ing angle sensor and lateral acceleration (Lg) sensor. Based on these signals, the control unit will determine the optimum
amount of wheel spin. Because the system is variable, the control unit may determine, depending on the driving condi-
tions, that some wheel spin is beneficial (thus enhancing straight-line acceleration), or that no wheel spin is beneficial
(thus enhancing cornering). For any given driving situation, the control unit will determine the amount of wheel spin best
suited to the driver's needs and, if necessary, will then signal the TCS control valve actuator, and engine ECU to reduce
engine power.
The system is automatically ‘‘ready’’ whenever the engine is started, but can be manually canceled with the TCS switch.
However, once activated, the system cannot be canceled until it is once again in the ready state.

Components:
® Wheel sensors: The TCS ‘’shares’’ the wheel sensors with the anti-lock brake system (ABS). The wheel sensors trans-
mit the wheel speed signals to the TCS contro! unit through the ABS control unit.
® Steering angle sensor: The steering angle sensor signals the TCS control unit about the amount of steering angle.
® Lg sensor: The Lg sensor detects the lateral acceleration of the vehicle and signals the TCS control unit.
e TCS control valve actuator: The actuator gets signals from the TCS control unit and closes the TCS control valve
accordingly.
® TCS control unit: The control unit gets driving condition signals from the sensors and, if necessary, signals the TCS
control valve actuator to close the TCS control valve, and the ECU to cut the fuel and retard the ignition timing.

System Description (TCS)
- Construction and Function
TCS Control Unit
Acceleration Control:
The TCS control unit gets signals from the wheel sensors about the rotational speed of each wheel. Traction control is
activated when the rotational speed of the driving wheels differs from the rotational speed of the driven wheels (i.e., vehicle
speed). .
Handling Control:
Based on signals about the left and right driven wheel rotational speeds, the control unit calculates the car's “yaw” rate (i.e., the
turn rate of the car's body). Based on signals from the steering angle sensor and driven wheel sensors, the control unit also
calculates the yaw rate expected by the driver. If the difference between actual and expected yaw rates is substantial-that is, if
the direction of the car's body will exceed the driver's expected line-the control unit signals the TCS control valve actuator, and
ECU, thus reducing engine power and maintaining the expected line.
Rough Road Control:
Based on signals from the wheel sensors, the control unit detects a rough road based on frequency of wheel rotational vibration.
The control unit then signals the TCS control valve actuator, and ECU to relax engine power, thus improving acceleration
efficiency.
Grip Control:
Based on signals about wheel speed and from lateral acceleration (Lg) sensor, the control unit determines the efficiency of the
grip of the tires on the road and signals the TCS control valve actuator, and ECU to relax engine power if necessary, thus
improving grip.

Fail-Safe Function:
Н the control unit detects an abnormality, it shuts the
traction control system off and causes the TCS indicator
light to come on. However if the abnormality is detected
while the TCS is activated, the control first establishes the
appropriate wheel spin velocity, then shuts the system
down, thus preventing excessive wheel spin.
Self-Diagnosis Function:
If the control unit detects an abnormality, it records a
Problem Code which can be used to diagnose the problem.
The code is shown at the TCS indicator light when the
Service Check connector terminals are connected with a
jumper wire.
Steering Angle Detection
Steering angle is detected by the steering angle sensor,
located on the steering column. The sensor uses two
magnetoresistor elements to determine steering angle and
direction of rotation. When the driver turns the steering
wheel, a magnet in the steering shaft generates waves in
the “MR” elements. These waves are amplified and
converted into signals which the control unit can interpret
as angle and direction of turn.

located at each wheel. The signals are sent to the control
unit, which compares each wheel's speed and determines
whether traction control is required.

Lateral Acceleration Detection
Lateral acceleration is detected by the lateral acceleration BRACKET Lg SENSOR
(Lg) sensor located behind the rear seat-back. The Lg
sensor varies the output voltage in accordance with the
left or right side acceleration and sends it to the TCS
control unit as a lateral acceleration signal.

Engine Output Control
When the TCS is activated, the TCS control unit signals the TCS control valve actuator and ECU. The actuator is linked to the
TCS control valve which is normally returned to fully open position by the two return springs.
Although the throttle valve is still within the driver's control, the engine output is relaxed by the TCS control valve and ECU to
achieve optimum traction,

System Description (TWS)
- Outline
Role of System
The tire air pressure is very important for safety driving and should be properly adjusted to maintain proper steering control and
low fuel consumption. Also, driving with low air pressure tires will adversely affect the tires and may damage them.
The Tire Pressure Watching System (TWS) is designed to make the driver check the tires immediately by warning with the
TWS indicator light when the air pressure of one or more tires is abnormal.
TWS INDICATOR LIGHT
0000000
ue _
Operating Principle
The lower air pressure tires rotates faster than the normal pressure tires during driving, because its diameter is smaller than the
one of the normal pressure tires.
Noting this fact, the TWS detects the drop of tire air pressure by means of the various sensor signals such as the wheel speed
signal of the anti-lock brake system.
Standard Wheel Speeds (Initial Offset Memory)
Even the new tires of the same brand have approximately 1% of difference in diameter, which affects directly to the wheel
speed. Therefore, it is necessary for the TWS control unit to memorize each wheel speed previously by actual driving. This
wheel speed memorized in the control unit is the standard wheel speeds (initial offset memory).
Blinking of TWS Indicator Light
When the TWS detects the abnormal tire pressure during driving, it blinks the TWS indicator light to warn the driver. When the
TWS indicator light warns of the abnormal tire pressure, the detected code can be shown with the TWS indicator light by
connecting the two terminals of the Service Check Connector with the jumper wire (see page 19-14). The abnormal pressure
tire can be determined by the blinking frequency of the TWS indicator light.
Detected Code Probable Cause
1-1 The pressure of either the left or right front tire is low.
1-2 The pressure of either the left or right rear tire is low.
The pressure of one of the four tires is low.
2-0 - This code may be detected when there is excessive wear difference between the left and right
front tires.
The pressures of either the two front tires or two rear tires are low.
+ This code may be detected under the following conditions:
3-0 —When the tire rotation is not performed and the front tires are worn excessively after the
standard wheel speeds (initial offset memory) is inputted in the control unit.
—When the car is driven at high speed with the low speed range tires installed.
— When the car is driven at high speed with the trailer towed.
NOTE:
The detected code memorized in the TWS control unit can be erased by disconnecting the ABS B2 (15 A) fuse.

fo
- Construction and Function
TWS Control Unit
The TWS control unit is integrated in the TCS control unit and shares the wheel speed signal, steering angle signal and lateral
acceleration signal with the TCS control unit. it measures the difference of the actual rotation speed between the left and right
wheels while estimating the normal difference of the rotation speeds between the wheels on both sides from the vehicle speed
and steering wheel angle.
If the system senses a difference between the values measured and estimated, which commonly indicates a low pressure, it
diagnoses a possibility of a flat tire.
NOTE:
e The TWS monitors the imbalance of the speed between the wheels. Therefore, the system does not blink the indicator light
when the tire air pressure of the four wheels decreased simultaneously.
* The TWS may blinks indicator light when the tire chains are installed on the wheels, when being towed with a trailer or under
other conditions when there are the significant differences in speed between the wheels.
Return the car to the original condition, restart the engine and test drive the car. The tire air pressure is normal if the TWS
indicator light does not blink.

Self-diagnosis Function
When the TWS is faulty, it turns the TWS indicator light on. Also, the TCS indicator light is turned on simultaneously. Therefore,
the problem can be checked by the TCS code.
Reset of TWS (For Proper Operation of TWS)
The standard wheel speeds memorized in the TWS control unit must be initialized and new standard wheel speeds must be
inputted into the control unit after the following:
e tire air pressure adjustment
e tire change
e tire rotation
e other occasions when the wheel speeds change
Reset the standard wheel speeds as follows:
1.Shift the transmission into |N| (neutral) or [P] (parking) and set the parking brake.
2. Start the engine.
3.Push the TCS switch and hold it until the TWS indicator light turns on (for more than 5 seconds), then release it. (The TWS
indicator light should go off.)
Input new standard wheel speeds as follows:
1.Connect the two terminals of the Service Check Connector with a jumper wire (see page 19-14) and make sure that the
TWS indicator light comes on.
2. Drive the car at more than 10 mph (16 km/h) until the TWS indicator light goes off (for 1-10 minutes).
(Input of the standard wheel speeds completes.)
3.Remove the jumper wire.

Troubleshooting (TCS)
—- TCS Indicator Light
N OWN
NOTE:
After the engine is started, the TCS indicator light goes off and TCS switch indicator light comes on to indicate that the system
is ready. If there is any abnormality in the system, the TCS indicator light stays on. Once the TCS switch is pushed, however,
the TCS indicator light comes on and TCS switch indicator light goes off to indicate that the system is off.
Temporary Driving Conditions:
1.
The TCS indicator light will come on and the control unit memorizes the Problem Code under certain temporary conditions:
* The spare tire is installed, or a tire of the improper size is installed.
* The tire pressures are not correct.
if the TCS indicator light does not come back on after correcting the tire or tire pressure problem, the system is OK.
NOTE:
Remove the ABS B2 (15A) fuse for at least three seconds to clear the code from the TCS control unit memory.
TCS Problem Code Indication:
Stop the engine.
Turn the ignition switch on and confirm that the TCS indicator light comes on.
Turn the ignition switch off.
Connect the two terminals of the Service Check Connector with a jumper wire.
Turn the ignition switch on, but do not start the engine.
Record the blinking frequency of the TCS indicator light. The blinking frequency indicates the code. Long blinks indicate the
main code; short blinks indicate the sub-code.
Refer to the Troubleshooting Guide {page 19-16) for repair information.

NOTE:
e The TCS control unit has three memory registers. When a problem occurs, the control unit stores the code in the first
memory register. If another problem occurs, the control unit moves the first code to the next memory register and stores the
second code in the first register. If there's a third problem occurrence, the two existing codes are moved up one register and
the third code is stored in the first register. If problems continue to occur, the oldest code is moved out of the last register
and lost, and the most recent code is stored in the first register.
e The TCS indicator light will not come on again after the engine starts unless another prblem occurrence is detected.
However, there will still be a code stored in the control unit's memory.
e After the repair is completed, disconnect the jumper wire from the Service Check connector and remove the ABS B2 (156A)
fuse from the under-hood fuse/relay box for at least 3 seconds to erase the control unit’s memory.
e The control unit's memory is erased if the connector is disconnected from the control unit, or if the control unit is removed
from the car. |

- Parking Brake Signal
Problem Cade 2: Parking brake signal
NOTE:
о Before proceeding to the troubleshooting procedure, be sure to perform a running test and check whether the TCS indicator
light comes on or not. If the TCS indicator light does not come on, the system is working properly. If the TCS indicator light
comes on, make sure the parking brake lever is released.
e When both of the rear wheels are running at 6 mph (10 km/h) or over and the parking brake is applied for more than 30
seconds continuously, the TCS control unit will cause the TCS indicator light to come on.
Release the parking brake
lever and turn the ignition

Troubleshooting (TCS)
- Steering Angle Sensor
Problem Code 2-1: Steering angle sensor
NOTE:
The TCS control unit performs the self-diagnosis for the steering angle sensor when the average speed of the two rear wheels
exceeds 10 mph (16 km/h). The TCS indicator light comes on if a yaw rate is generated and the steering angle signal that
corresponds to this yaw rate is not inputted when the steering wheel is turned, while there is no input from the STOP (brake
light signal) and PARK (parking brake signal).
NOTE:
Start the engine. e Steps 1 through 4 are the steering angle sensor check procedures for
actual vehicle operating conditions.
This will be called the “steering angle sensor system check” in the
1.
following sections.

Read this before you do any electrical work on the car.
The Legend Coupe Supplemental Restraint System (SRS) includes a driver's airbag, located in the steering wheel
hub, a front passenger's airbag, located in the dashboard above the glove box, and seat belt pretensioners, located
in the seat belt retractors.
Information necessary to safely service the SRS is included in the ‘93 Legend Coupe Shop Manual Supplement
(62SP121). Items marked with an asterisk (*) on the contents page include, or are located near, SRS components.
Servicing, disassembling or replacing these items will require special precautions and tools, and should therefore
be done only by an authorized Honda dealer.
A WARNING
e To avoid rendering the SRS inoperative, which could lead to personal injury or death in the event of a severe
frontal collision, all SRS testing and repair must be done by an authorized Honda dealer.
® Improper procedures, including incorrect removal and installation of the SRS components, could lead to per-
sonal injury caused by unintentional activation of the airbags and seat belt pretensioners. |
e All SAS electrical wiring harnesses are covered with yellow outer insulation. Related components are located
in the steering column, center console and armrest, dashboard lower panel, and in the dashboard above the
glove box. Do not use electrical test equipment on these circuits.

CAUTION: |
e All SRS wiring harnesses are covered with yellow out-
er insulation.
e Before disconnecting any part of the SRS wire har-
ness, install the short connectors.
e Replace the entire affected SRS harness assembly if
it has an open circuit or damaged wiring.
Remove the dashboard lower panel, then disconnect the
14-P and 10-P connector from the control unit.
Inspect the connector and socket terminals to be sure
they are all making good contact.
e If the terminals are bent, loose or corroded, repair them
as necessary, and recheck the system.
e If the terminals look OK, make the following input tests
at the connector.
— If any test indicates a problem, find and correct the
cause, then recheck the system.
— If all the input tests prove OK, the control unit must
be faulty; replace it.
NOTE:
® Several different wires have the same color. They have
been given a number suffix to distinguish them (for
example, GRN/RED' and GRN/RED? are not the
same).

NOTE: Before proceeding to testing, make sure that the
door lock system is functioning properly.
1. Adjust the voltage select switch according to local
requirements, then connect the Keyless Entry Check-
er to an AC power outlet, and check that the power
indicator light goes on.
2. Place the ignition key (transmitter) within 500 mm
{19.7 in) from the front of the infrared ray window,
and press the transmit button on the ignition key
(transmitter). Check that the ray indicator light goes
on.
e If the ray indicator light goes on, go to step 3.

e If the ray indicator light does not go on, insert the
ignition key into the keyless entry checker (the
charge indicator light goes on), then check again.
NOTE: If the short circuit indicator light goes on,
pull out the ignition key once and reinsert.
— If the ray indicator light goes on, go to step 4. |
— If it does not go on, check for contaminated
or deformed ignition key tip.
If the key tip is not contaminated or deformed,
the ignition key (transmitter) itself is faulty.

Connect the positive ( +) probe of the digital mul-
timeter to the GRN/WHT terminal and the nega-
tive (—) probe to the GRN/BLK terminal.
® Trunk receiver unit
Connect the positive ( +) probe of the digital mul-
timeter to the GRN/YEL terminal and the negative
(—) probe to the GRN/BLK terminal.
NOTE:
e Keep the 4-P (3-P) connector connected.
e Use a digital multimeter (DC range).
— If the output voltage momentarily changes to
the range of approx 3.5 mV — 1 V, go to step 4.
— If there is no voltage, check for contaminated
sensor on the receiver and external damage.
If the sensor is not contaminated and there is
no external damage, the receiver is faulty.
