



Always perform automotive testing in a safe environment.
Wear safety eye protection that meets ANSI standards.
Keep clothing, hair, hands, tools, test equipment, etc. away from
all moving or hot engine parts.
Operate the vehicle in a well ventilated work area: Exhaust gases
are poisonous.
Put blocks in front of the drive wheels and never leave the vehicle
unattended while running tests.
Use extreme caution when working around the ignition coil,
distributor cap, ignition wires and spark plugs. These
components create hazardous voltages when the engine is
running.
Put the transmission in PARK (for automatic transmission) or
NEUTRAL (for manual transmission) and make sure the parking
brake is engaged.
Keep a fire extinguisher suitable for gasoline/chemical/ electrical
fires nearby.
Don’t connect or disconnect any test equipment while the
ignition is on or the engine is running.
Keep the scan tool dry, clean, free from oil/water or grease. Use a
mild detergent on a clean cloth to clean the outside of the scan
tool, when necessary.

2. General Information
2.1 On-Board Diagnostics (OBD) II
The first generation of On-Board Diagnostics (called OBD I) was
developed by the California Air Resources Board (ARB) and
implemented in 1988 to monitor some of the emission control
components on vehicles. As technology evolved and the desire to
improve the On-Board Diagnostic system increased, a new generation
of On-Board Diagnostic system was developed. This second generation
of On-Board Diagnostic regulations is called "OBD II".
The OBD II system is designed to monitor emission control systems
and key engine components by performing either continuous or
periodic tests of specific components and vehicle conditions. When a
problem is detected, the OBD II system turns on a warning lamp (MIL)
on the vehicle instrument panel to alert the driver typically by the
phrase of “Check Engine” or “Service Engine Soon”. The system will
also store important information about the detected malfunction so
that a technician can accurately find and fix the problem. Here below
follow three pieces of such valuable information:
1) Whether the Malfunction Indicator Light (MIL) is
commanded 'on' or 'off';
2) Which, if any, Diagnostic Trouble Codes (DTCs) are stored;
3) Readiness Monitor status.
2.2 Diagnostic Trouble Codes (DTCs)
OBD II Diagnostic Trouble Codes are codes that are stored by the
on-board computer diagnostic system in response to a problem found
in the vehicle. These codes identify a particular problem area and are
intended to provide you with a guide as to where a fault might be
occurring within a vehicle. OBD II Diagnostic Trouble Codes
consists of a five-digit alphanumeric code. The first character, a letter,
identifies which control system sets the code. The other four
characters, all numbers, provide additional information on where the
DTC originated and the operating conditions that caused it to set. Here
below is an example to illustrate the structure of the digits:
2
2.3 Location of the Data Link Connector (DLC)
The DLC (Data Link Connector or Diagnostic Link Connector) is the
standardized 16-cavity connector where diagnostic scan tools
interface with the vehicle's on-board computer. The DLC is usually
located 12 inches from the center of the instrument panel (dash),
under or around the driver’s side for most vehicles. If Data Link
Connector is not located under dashboard, a label should be there
telling location. For some Asian and European vehicles, the DLC is
located behind the ashtray and the ashtray must be removed to access
the connector. If the DLC cannot be found, refer to the vehicle’s
service manual for the location.
3
2.4 OBD II Readiness Monitors
An important part of a vehicle’s OBD II system is the Readiness
Monitors, which are indicators used to find out if all of the emissions
components have been evaluated by the OBD II system. They are
running periodic tests on specific systems and components to ensure
that they are performing within allowable limits.
Currently, there are eleven OBD II Readiness Monitors (or I/M
Monitors) defined by the U.S. Environmental Protection Agency
(EPA). Not all monitors are supported by all vehicles and the exact
number of monitors in any vehicle depends on the motor vehicle
manufacturer’s emissions control strategy.
Continuous Monitors -- Some of the vehicle components or systems
are continuously tested by the vehicle’s OBD II system, while others
are tested only under specific vehicle operating conditions. The
continuously monitored components listed below are always ready:
1)Misfire
2)Fuel System
3)Comprehensive Components (CCM)
Once the vehicle is running, the OBD II system is continuously
checking the above components, monitoring key engine sensors,
watching for engine misfire, and monitoring fuel demands.
Non-Continuous Monitors -- Unlike the continuous monitors, many
emissions and engine system components require the vehicle to be
operated under specific conditions before the monitor is ready. These
4
monitors are termed non-continuous monitors. For different ignition
type engines, the available monitors are different too.
The following monitors are to be used for spark ignition engines
only:
1)
2)
3)
4)
5)
6)
7)
EGR System
O2 Sensors
Catalyst
Evaporative System
O2 Sensor Heater
Secondary air
Heated Catalyst
The following monitors are to be used for compression ignition
engines only:
1)
2)
3)
4)
5)
6)
EGR System
NMHC Catalyst
NOx aftertreatment
Boost pressure system
Exhaust gas sensor
PM filter
2.5 OBD II Monitor Readiness Status
OBD II systems must indicate whether or not the vehicle’s PCM’s
monitor system has completed testing on each component.
Components that have been tested will be reported as “Ready”, or
“Complete”, meaning they have been tested by the OBD II system.
The purpose of recording readiness status is to allow inspectors to
determine if the vehicle’s OBD II system has tested all the
components and/or systems.
The power-train control module (PCM) sets a monitor to “Ready” or
“Complete” after an appropriate drive cycle has been performed. The
drive cycle that enables a monitor and sets readiness codes to “Ready”
varies for each individual monitor. Once a monitor is set as “Ready”
or “Complete”, it will remain in this state. A number of factors,
5
including erasing of diagnostic trouble codes (DTCs) with a scan tool
or a disconnected battery, can result in Readiness Monitors being set
to “Not Ready”. Since the three continuous monitors are constantly
evaluating, they will be reported as “Ready” all of the time. If testing
of a particular supported non-continuous monitor has not been
completed, the monitor status will be reported as “Not Complete” or
“Not Ready.”
In order for the OBD monitor system to become ready, the vehicle
should be driven under a variety of normal operating conditions.
These operating conditions may include a mix of highway driving and
stop and go, city type driving, and at least one overnight-off period.
For specific information on getting your vehicle’s OBD monitor
system ready, please consult your vehicle owner’s manual.
2.6 OBD II Definitions
Power-train Control Module (PCM) -- OBD II terminology for the
on-board computer that controls engine and drive train.
Malfunction Indicator Light (MIL) -- Malfunction Indicator Light
(Service Engine Soon, Check Engine) is a term used for the light on
the instrument panel. It is to alert the driver and/or the repair
technician that there is a problem with one or more of vehicle's
systems and may cause emissions to exceed federal standards. If the
MIL illuminates with a steady light, it indicates that a problem has
been detected and the vehicle should be serviced as soon as possible.
Under certain conditions, the dashboard light will blink or flash. This
indicates a severe problem and flashing is intended to discourage
vehicle operation. The vehicle onboard diagnostic system can not turn
the MIL off until necessary repairs are completed or the condition no
longer exists.
DTC -- Diagnostic Trouble Codes (DTC) that identify which section
of the emission control system has malfunctioned.
Enabling Criteria -- Also termed Enabling Conditions. They are the
vehicle-specific events or conditions that must occur within the
engine before the various monitors will set, or run. Some monitors
require the vehicle to follow a prescribed “drive cycle” routine as part
6
of the enabling criteria. Drive cycles vary among vehicles and for
each monitor in any particular vehicle.
OBD II Drive Cycle -- A specific mode of vehicle operation that
provides conditions required to set all the readiness monitors
applicable to the vehicle to the “ready” condition. The purpose of
completing an OBD II drive cycle is to force the vehicle to run its
onboard diagnostics. Some form of a drive cycle needs to be
performed after DTCs have been erased from the PCM’s memory or
after the battery has been disconnected. Running through a vehicle’s
complete drive cycle will “set” the readiness monitors so that future
faults can be detected. Drive cycles vary depending on the vehicle and
the monitor that needs to be reset. For vehicle specific drive cycle,
consult the vehicle’s Owner’s Manual.
Freeze Frame Data -- When an emissions related fault occurs, the
OBD II system not only sets a code but also records a snapshot of the
vehicle operating parameters to help in identifying the problem. This
set of values is referred to as Freeze Frame Data and may include
important engine parameters such as engine RPM, vehicle speed, air
flow, engine load, fuel pressure, fuel trim value, engine coolant
temperature, ignition timing advance, or closed loop status.

3.7 Vehicle Coverage
The MaxiService®EBS301 Scanner is specially designed to work with
all OBD II compliant vehicles, including those equipped with
universal protocol -- Control Area Network (CAN). It is required by
EPA that all 1996 and newer vehicles (cars and light trucks) sold in the
United States must be OBD II compliant and this includes all
Domestic, Asian and European vehicles.
A small number of 1994 and 1995 model year gasoline vehicles are
OBD II compliant. To verify if a 1994 or 1995 vehicle is OBD II
compliant, check the Vehicle Emissions Control Information (VECI)
Label which is located under the hood or by the radiator of most
vehicles. If the vehicle is OBD II compliant, the label will designate
“OBD II Certified”. Additionally, Government regulations mandate
that all OBD II compliant vehicles must have a “common” sixteen-pin
Data Link Connector (DLC).
15
For your vehicle to be OBD II compliant it must have a 16-pin DLC
(Data Link Connector) under the dash and the Vehicle Emission
Control Information Label must state that the vehicle is OBD II
compliant.
3.8 Product Troubleshooting

5.1 Read Codes
 Reading Codes can be done with the key on engine off (KOEO)
or with the key on engine running (KOER).
 Stored Codes are also known as “hard codes”, which are fault
codes, or trouble codes that have been stored in the vehicle
computer memory because the faults have reoccurred for
20
more than a specified amount of key-cycles. These codes will
cause the control module to illuminate the malfunction
indicator light (MIL) when emission-related fault occurs.
 Pending Codes are also referred to as “maturing codes” or
“continuous monitor codes”. They indicate problems that the
control module has detected during the current or last driving
cycle but are not considered serious yet. Pending Codes will
not turn on the malfunction indicator lamp (MIL). If the fault
does not occur within a certain number of warm-up cycles, the
code clears from memory.
 Permanent Codes are DTCs that are "confirmed" and are
retained in the non-volatile memory of the computer until the
appropriate monitor for each DTC has determined that the
malfunction is no longer present and is not commanding the
MIL on. Permanent DTC shall be stored in non-volatile
memory and may not be erased by any diagnostic services or
by disconnecting power to ECU.

computer, but also “Freeze Frame” data and manufacturer
specific enhanced data. Further, the I/M Readiness Monitor Status
for all vehicle monitors is reset to Not Ready or Not Complete
status. Do not erase the codes before the system has been checked
completely by a technician.
NOTE: Erasing codes does not mean that trouble codes in
ECU have been eliminated completely. As long as there is
fault with the vehicle, the trouble codes keeps on presenting.
 This function is performed with key on engine off (KOEO). Do
not start the engine.
1) Use the UP/DOWN scroll buttons to select Erase Codes from
Diagnostics Menu and press the OK button. (Figure 5.3)

5.5 Retrieving I/M Readiness Status
I/M Readiness function is used to check the operations of the
Emission System on OBD2 compliant vehicles. It is an excellent
function to use prior to having a vehicle inspected for
compliance to a state emissions program.
CAUTION - By clearing trouble codes you also clear the readiness
status for the individual emission system readiness tests. In order
to reset these monitors, the vehicle must be driven through a
complete drive cycle with no trouble codes in memory. Times for
reset vary depending on vehicle.
Some latest vehicle models may support two types of I/M
Readiness tests:
A.
B.
Since DTCs Cleared - indicates status of the monitors since the
DTCs are erased.
This Drive Cycle - indicates status of monitors since the
beginning of the current drive cycle.
An I/M Readiness Status result of “NO” does not necessarily
indicate that the vehicle being tested will fail the state I/M
inspection. For some states, one or more such monitors may be
allowed to be “Not Ready” to pass the emissions inspection.
 “OK” -- Indicates that a particular monitor being checked has
completed its diagnostic testing.
 “INC” -- Indicates that a particular monitor being checked has
not completed its diagnostic testing.
 “N/A” -- The monitor is not supported on that vehicle.
32
1) Use the UP/DOWN scroll button to select I/M Readiness from
Diagnostic Menu and press OK button. (Figure 5.3)
2) Wait a few seconds while the scan tool validates the PID MAP.

5.7 On-Board Monitor Test
The On-Board Monitor Test is useful after servicing or after
erasing a vehicle’s control module memory. The On-Board
Monitor Test for non-CAN-equipped vehicles retrieves and
displays test results for emission-related power train components
and systems that are not continuously monitored. The On-Board
Monitor Test for CAN-equipped vehicles retrieves and displays
test results for emission-related power train components and
systems that are and are not continuously monitored. Test and
components IDs are determined by the vehicle manufacturer.
In this test, there are typically a minimum value, a maximum value,
