WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN IGNITION
OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BEFORE
PROCEEDING.
WARNING: IF THE AIRBAG CONTROL MODULE IS DROPPED AT ANY
TIME, IT MUST BE REPLACED. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT
AND PERSONAL INJURY OR DEATH.
If there are no possible causes remaining, view repair.

All

Repair

Replace the Airbag Control Module in accordance with Service
Instructions.
Perform AIRBAG VERIFICATION TEST - VER 1.

NOTE: Ensure the battery is fully charged.
With the DRBIII

t, record and erase all DTCs from all modules.

All active codes must be resolved before diagnosing any stored codes.
Maintain a safe distance from all airbags while performing the following steps.
With the DRBIII

t monitor active codes as you work through the system.

NOTE: If equipped with Passenger Airbag On-Off switch, read the DTC’s in
all switch positions.
Wiggle the wiring harness and connectors of the appropriate airbag system and
rotate the steering wheel from stop to stop.
NOTE: Check connectors - Clean and repair as necessary.
You have just attempted to simulate the condition that initially set the trouble code
message.
The following additional checks may assist you in identifying a possible intermittent
problem:
- Visually inspect related wire harness connectors. Look for broken, bent, pushed out,
spread, corroded, or contaminated terminals.
- Visually inspect the related harnesses. Look for chafed, pierced, pinched or partially
broken wire.
- Refer to Wiring Diagrams and Technical Service Bulletins that may apply.
Did the DTC become active ?

All

Yes

→ Select appropriate symptom from Symptom List.

→ No problem found at this time. Erase all codes before returning

vehicle to customer.

WARNING: TURN IGNITION OFF, DISCONNECT THE BATTERY AND WAIT
TWO MINUTES BEFORE PROCEEDING.
If there are no possible causes remaining, view repair.

All

Repair

Replace the Left Side Impact Airbag Control Module in accordance
with Service Instructions. WARNING: IF THE MODULE IS
DROPPED AT ANY TIME, IT MUST BE REPLACED.

Symptom:

LOSS OF IGNITION RUN ONLY

When Monitored and Set Condition:

LOSS OF IGNITION RUN ONLY

When Monitored:

With the ignition in the run position the module monitors the Run Only

circuit for proper system voltage.

Set Condition:

If the voltage on the Run Only circuit drops below 4.5 volts, the code will

set.

POSSIBLE CAUSES

IGNITION SWITCH OUTPUT RUN CIRCUIT OPEN

FUSED IGNITION SWITCH OUTPUT RUN CIRCUIT OPEN

ACM, FUSED IGNITION OUTPUT RUN CIRCUIT OPEN

CHECKING FOR A SHORTED RUN CIRCUIT

FUSED IGNITION SWITCH OUTPUT RUN CIRCUIT SHORT TO GROUND

ACM, FUSED IGNITION RUN CIRCUIT SHORT TO GROUND
