light MITSUBISHI ENDEAVOR 2004 Service Repair Manual

LONG STOPPING DISTANCES ON LOOSE ROAD SURFACESWhen braking on loose surfaces like snow-covered or gravel roads, the stopping
distance can be longer for an ABS-equipped vehicle than the stopping distance for a
vehicle with a conventional brake system. SHOCK AT STARTING CHECK Shock may be felt when the brake pedal is lightly pressed while driving at a low
speed. This is a normal characteristic because the ABS system operation check is
carried out when vehicle speed is 8 km/h (5 mph) or less. ANTI-LOCK BRAKING SYSTEM (ABS) DIAGNOSIS INTRODUCTION TO ANTI-LOCK BRAKING SYSTEM DIAGNOSIS The anti-lock braking system (ABS) operates differently from conventional brake
systems. These differences include sounds, sensations, and vehicle performance that
owners and service technicians who are not familiar with ABS may not be used to.
Some operational characteristics may seem to be malfunctions, but they are simply
signs of normal ABS operation. When diagnosing the ABS system, keep these
operational characteristics in mind. Inform the owner of the kind of performance
characteristics to expect from an ABS-equipped vehicle. ABS DIAGNOSTIC TROUBLE CODE DETECTION CONDITIONS ABS diagnostic trouble codes (ABS DTCs) are set under different conditions,
depending on the malfunction detected. Most ABS DTCs will only be set during
vehicle operation. Some ABS DTCs will also be set during the ABS self-check
immediately after the engine is started.
When you check if an ABS DTC will be displayed again after the DTC has been
erased, you should duplicate the ABS DTC set conditions. Depending on the
detection timing and set conditions for the specific ABS DTC, you must either drive
the vehicle or turn the engine off and restart it. To set the proper conditions for that
DTC again, refer to ABS DTC SET CONDITIONS
for each ABS DTC that you
are trying to reset.

TECHNICAL DESCRIPTION (COMMENT)
The ABS-ECU sends the ABS warning light and the brake warning light
signals to the combination meter via the CAN communication. This may be caused by faults in the CAN bus line, the combination meter or
the ABS-ECU.

DESCRIPTION & OPERATION Supplemental Restraint System (SRS) components on vehicles with single-stage air
bag systems include single-stage driver-side and passenger-side air bag modules,
side impact air bag modules, seat belt pretensioners, front impact sensors, side
impact sensors, SRS Electronic Control Unit (SRS ECU) and an AIR BAG warning
light or SRS warning light.
SRS components on vehicles with dual-stage air bag systems include dual-stage
driver-side and passenger-side air bag modules, side impact air bag modules, seat
belt pretensioners, front impact sensors, side impact sensors, SRS Electronic
Control Unit (SRS ECU), occupant classification sensor, occupant classification
sensor ECU, seat belt switches, AIR BAG warning light or SRS warning light,
PASSENGER AIR BAG OFF warning light and a PASSENGER SEAT BELT
warning light. COMPONENT LOCATIONS Refer to illustration for SRS com
ponent locations. See
Fig. 1
&

WARNING:Accidental air bag deployment is possible. Personal
injury may result. Read and follow all WARNINGS
and AIR BAG SAFETY PRECAUTIONS
before
working on air bag system or related components.

SYSTEM OPERATION CHECK Turn ignition on. AIR BAG warning light should come on for about 7 seconds and
then turn off, indicating SRS is functioning properly. If AIR BAG warning light
does not function as described, SRS is malfunctioning and needs repair. See DIAGNOSTICS

WARNING:Accidental air bag deployment is possible. Personal

and AIR BAG SAFETY PRECAUTIONS

Observe these precautions when servicing the air bag system:
Disable SRS before servicing any SRS component. Failure to do this may
result in accidental air bag deployment and possible personal injury. See DISABLING & ACTIVATING AIR BAG SYSTEM
.
After disabling SRS, wait at least 60 seconds before servicing SRS. After servicing, always turn ignition on from outside of vehicle in case of
accidental air bag module deployment. After servicing, check AIR BAG warning light to verify system operation. See SYSTEM OPERATION CHECK
.
Always wear safety glasses when servicing or handling an SRS component. Hearing protection must be worn when performing deployment procedures. DO NOT expose air bag modules, clockspring or SRS ECU to temperatures
greater than 200°F (93°C ). DO NOT expose seat belt pretensioners to temperatures greater than 194°F
(90°C ). When placing a live air bag module on a bench or other surface, always place
air bag module with trim cover facing up and away from surface. This will
reduce motion of air bag module if accidental deployment occurs. After air bag module deploys, surrounding surfaces may contain deposits of
sodium hydroxide, which irritates skin. Always wear safety glasses, rubber
gloves and a long-sleeved shirt during clean-up. Wash hands using mild soap
and water. Follow correct clean-up and disposal procedures. See
DISPOSAL
PROCEDURES
.
Because of critical system operating requirements, DO NOT service any SRS
components. Repairs are only made by replacing defective components. DO NOT allow any electrical source near inflator on back of air bag module. When carrying a live (undeployed) air bag module, trim cover must be pointed
away from body to minimize injury in case of accidental air bag deployment. If instructed to probe wire harness, do so from harness side of connector. DO NOT probe a wire through insulator. Wire will be damaged and eventually
fail due to corrosion. When
performin
g electrical tests,
prevent accidental shortin
g of terminals.

Such shorts can damage fuses or components and may cause a second
Diagnostic Trouble Code (DTC) to set, making diagnosis of original problem
more difficult. Never use an analog volt/ohm meter or test light in place of a Digital Volt/Ohm
Meter (DVOM). Use only a DVOM with a maximum test current of 2 mA
(milliamps) at minimum range of resistance measurement. If SRS is not fully functional for any reason, DO NOT drive vehicle until
system is repaired and fully functional. DO NOT remove bulbs, modules,
sensors, or other components or in any way disable system from operating
normally. If SRS is not functional, park vehicle until repairs are made.
DISABLING & ACTIVATING AIR BAG SYSTEM To disable system, turn ignition off. Disconnect negative battery cable. Shield cable
end with electrical tape. Wait at least 60 seconds before servicing air bag system.
To activate system, reconnect negative battery cable. Check system operation. See SYSTEM OPERATION CHECK
.
DISPOSAL PROCEDURES DEPLOYED AIR BAG OR SEAT BELT PRETENSIONER Place deployed component in a strong plastic bag and seal tightly. Dispose of
component as you would any other part. No other special disposal procedure is
required. UNDEPLOYED AIR BAG OR SEAT BELT PRETENSIONER
WARNING:Accidental air bag deployment is possible. Personal
injury may result. Read and follow all WARNINGS
and AIR BAG SAFETY PRECAUTIONS
before
working on air bag system or related components.
NOTE: Undeployed air bag modules must be deployed before
disposal. Disposing of an undeployed air bag may violate
federal, state and/or local laws. This also applies to vehicles
that are to be scrapped.
