2004 MITSUBISHI ENDEAVOR light

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.

1. Turn ignition on. If AIR BAG warning light comes on for 7 seconds and then
goes off, SRS is functioning properly. If AIR BAG warning light does not
function as described, turn ignition off. If AIR BAG warning light malfunction
or scan tool communication problems are encountered, diagnose malfunction
using appropriate table. SeeSCAN TOOL COMMUNICATION

. If wire harness and connectors are damaged, replace wire harness. Go
to step 8 . If wire harness and connectors are okay, go to step 8 .
4. Replace fuse. Turn ignition on for at least one minute, then off. Inspect fuse. If
fuse is okay, go to step 8 . If fuse is not okay, go to next step.
5. Disconnect connector C-211 from junction block. Check for continuity
between ground and terminal No. 7 (Yellow/Black wire) of connector C-211. I
f
continuity exists, check all circuits associated with fuse No. 3 for a short to
ground. If continuity does not exist, go to next step.
6. Disconnect SRS ECU connector C-26. Check for continuity between SRS ECU
connector C-26, terminal No. 13 (Black/White wire) and ground. If continuity
exists, go to next step. If continuity does not exist, erase, then retrieve DTCs
using scan tool. If DTC 42 is retrieved, replace SRS ECU. Go to step 8 .
7. Check Black/White wire between SRS ECU connector C-26, terminal No. 13
and junction block connector C-205, terminal No. 7 for an open, short or
damage. If wire is okay, go to next step. If wire is not okay, replace wire
harness and go to next step.
8. Reconnect all SRS components. Activate air bag system. Using scan tool, erase
then retrieve DTCs. If DTC 42 is retrieved, go to step 1 . If DTC 42 is not
retrieved, system is normal at this time. Intermittent condition may exist.
DTC 43: AIR BAG WARNING LIGHT DOES NOT ILLUMINATE 1. Before proceeding, see AIR BAG SAFETY PRECAUTIONS
. Disable air
bag system. See DISABLING & ACTIVATING AIR BAG SYSTEM
.
Disconnect SRS ECU connector C-26. See SRS ELECTRONIC CONTROL
UNIT (SRS ECU)
under REMOVAL & INSTALLATION. See Fig. 19

Connect negative battery cable. Turn ignition on. If AIR BAG warning light
does not illuminate, go to next step. If AIR BAG warning light illuminates, go
to step 3 .
2. Inspect wire harness between ignition switch connector C-308 and SRS ECU
connector C-26 and between C-26 and combination meter connector C-102 for
damage, a short or open circuit. If wire harness is okay, replace combination
meter assembly. Go to next step. If wire harness is not okay, replace wire
harness. Go to next step.
3. Reconnect all SRS com
