CHASSIS ELECTRICAL 54A-4 IMMOBILIZER SYSTEM SPECIFICATION Item 54203 56103 Voltage V 12 12 Capacity (20-hour rate) Ah 42 61 Electrolytic fluid specific gravity (fully charged state 1.280 at 20°C) 1.280 IMMOBILIZER SYSTEM M2540003000188 The engine immobilizer system prevents the engine from starting and immobilizes the vehicle if a key other than the key registered for that vehicle is used in an attempt to start the engine after forced entry. The engine immobilizer system consists of the ignition key, key ring antenna, immobilizer-ECU, and engine-ECU <M/T> or engine automated manual transmission electronic control unit (engine-A-M/T-ECU) <automated manual transmission>. It works in the following way and has these functions. 1. With the ignition key turned ON, the transponder (a small transmitter) integrated in the ignition key transmits its own ID code to the key ring antenna via radio wave. 2. According to the sent ID code, the ETACS-ECU controls the engine-ECU <M/T> or engine-A-M/T-ECU <automated manual transmission> only when the sent ID code agrees with the pre-registered one. 3. The system is designed to be maintenance-free because the power source for the transponder is supplied by the key ring antenna. Three ignition keys are provided, and up to eight keys can be registered to one vehicle as needed. More than one trillion of ID code combinations can be registered, and parts of them are irregularly changed whenever the ignition key is turned ON. This feature prevents code copying, resulting in higher security of the system. NOTE: In case of replacement of the ETACS-ECU, or loss or addition of the ignition key, all key ID codes should be registered again using MUT-III as follows. . • In case of loss of the ignition key, all keys except the lost one should be registered again for eliminating the registration of the lost key. • For addition of a key, all the keys to be used afterwards including the added key should be registered again.

When the transponder receives random number data, it processes it and the encrypted code. Then it transmits the process result to the ETACS-ECU. Key ring antenna (included The ETACS-ECU supplies power via an antenna on a steering lock by an amplifier) transmission of electromagnetic waves to a transponder built into a key, using magnetic coupling ETACS-ECU (immobilizer-ECU integration) • Supplies electrical power to the transponder integrated in the ignition key, and transmits random number data. • Verifies the encrypted code which is sent from the transponder. If the code is correct, it sends an engine mobilization signal to the engine-ECU <M/T> or engine-transmission-ECU <Automated manual transmission>. Engine-ECU <M/T> or engine-transmission-ECU <Automated manual transmission> Starts the engine, and then continues the engine running if an engine mobilization signal is confirmed. If an engine immobilization signal is confirmed, the ECU cancels the engine control and stops the engine. Encrypted code registration criteria table The ignition key contains a transponder (small transmitter), which retains an unique encrypted code. Under any of the conditions below, the encrypted code should be registered in the ETACS-ECU again. The ETACS-ECU can retain maximum eight different encrypted codes. This means that maximum eight ignition keys can be registered. Component to be replaced Engine-ECU <M/T> or engine-A/T-ECU <A/T> Engine-ECU <M/T> or engine-A/T-ECU <A/T> is replaced − When engine-ECU <M/T> or engine-A/T-ECU <A/T> is overwritten − ETACS-ECU Ignition key Should not be replaced Should not be replaced Should not be replaced Should not be replaced Should be registered again Should be registered again CHASSIS ELECTRICAL 54A-6 LIGHTING Should not be replaced − When ignition key is added Should not be replaced Should not be replaced • Additional ignition key should be registered • All ignition keys should be registered again When ignition key is lost Should not be replaced Should not be replaced All the ignition keys other than the lost one should be registered again When ETACS-ECU is replace Should not be replaced All ignition keys should be registered again NOTE: When ETACS-ECU or engine-ECU <M/T> or engine-transmission-ECU <automated manual transmission> is replaced, reinput the vehicle information with the variant coding, using the MUT-III.

The headlamp levelling function is a system that allows the driver to change the direction of headlamp beam so that the drivers of oncoming cars are not dazzled by the headlamps. The headlamp levelling switch allows changing the direction in five steps: 0 to 4. CHASSIS ELECTRICAL 54A-8 LIGHTING Relationship between the switch positions and the number of passengers/loads Switch position 0 1 2 3 4 Passenger and load When a more load than those to the left is on the vehicle Driver only or driver and one passenger AC301941AB Driver and four passenger, and loads AC301943AB Driver and four passenger AC301942AB Driver and heavy loads AC301944AB OPERATION 1. The headlamp levelling switch increases the resistance as it is turned from 0 to 4. Turning the headlamp levelling switch changes the voltage at point A. When the headlamp levelling switch is turned from 0 to 4, the voltage at point A decreases. Upon detection of this voltage change, the headlamp levelling unit turns the motor to lower the beam direction. At this time, the resistance of the variable resistor in the headlamp assembly changes, and the voltage at point B decreases gradually. When the voltages at points A and B become equal, the headlamp levelling unit stops the motor. 2. Turning the headlamp levelling switch from 4 to 0 increases the voltage at point A, and then the headlamp levelling unit turns the motor in the direction opposite to that mentioned in Item 1, increasing the voltage at point B. When the voltages at points A and B become equal, the headlamp levelling unit stops the motor. 3. The headlamp levelling unit detects voltage changes caused by headlamp levelling switch operation, and turns the motor to change the directions of the headlamp deflectors for the adjustment of the headlamp beam direction.

Designed to be easy-to-distinguish by drivers, the gauges are arranged with the speedometer in the middle, the fuel gauge at left, and the tachometer at right. The combination meter offers the following advantages. • CAN communication is used for more reliable transmission of all gauge data and indicator lamp input signals, such as vehicle speed, engine RPM, and coolant temperature. For further details on CAN, refer to P.54C-2 GROUP 54C, CAN. The signals that the combination meter uses are described in the CAN communications input signals table . • Several diagnosis functions such as the diagnosis code memory and actuator tests are prepared in order to improve serviceability. • The large passenger air bag off indicator is installed in the meter. • The daytime dipper button is installed in the meter. • For a brighter display at night and for a longer useful life, all indicator lamps, warning lamps, and illumination bulbs use LEDs. • The indicators for the speedometer, fuel gauge, and other gauges are driven by a stepping motor. For further details, consult the stepping motor section P.54A-10. • The electric speedometer is adopted so that it is operated by vehicle speed signals sent from engine-ECU or engine-A-M/T ECU via CAN communication. • A large and clear LCD type odo-tripmeter is provided. The odometer continuously displays values while the tripmeter adopts a twin-trip (trip A, trip B) function which is switched by a reset button. Also the shift indicator features a clearly visible LCD display. • Comes with a front and rear fog lamp indication lamps to let the driver know that the fog lamp is on. • A seat belt warning lamp is installed to encourage the driver to fasten the seat belt. • The speedometer is an electronic type speedometer which operates by the pulse signal generated by the vehicle speed sensor. • The fuel gauge is provided with a triangular mark indicating the location of the fuel filler door to clearly that the fuel filler door is on the left side of the car.

Compared with conventional movements, the torque for driving the indicators is much greater for superior indicator accuracy and more stable response. The indicator position displayed is determined as the microcontroller circuit in the gauge controls the stepping motor. In conventional gauges, the indicator revolves 360° in response to 360° driving controls. However, a stepping motor is designed so that the indicator revolves only 45°, even in response to a drive control of 360°. The 45° drive control must be repeated to make the indicator rotate 360°. Thus, at a position 45° away from the indicator display position, there will be an identical control. As a result, in the case of a great impact such as from an accident when the indicator becomes misaligned, if the ignition is switched on to start driving while the indicator is misaligned, the indicator will function while misaligned. Thus, to return the indicator to the normal position in case this happens, when the ignition is switched on, the indicator positions are reset to their respective positions after the battery line is connected after it is cut. After the battery line is cut and reconnected, the indicators simply return to the zero position. The same operation is performed after voltage is restored if gauge functions are lost because of a voltage drop from cranking or the like. Furthermore, the indicator only returns 45° after the ignition is switched on or the lock is turned off. The indicator is not moved if it is not misaligned.
