With the DRBIII

t, record and erase all DTC’s from all Airbag modules.

If equipped with Passenger Airbag On - Off switch, read the DTC’s in all switch
positions.
If any ACTIVE codes are present they must be resolved before diagnosing any stored
codes.
WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNI-
TION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BE-
FORE PROCEEDING.
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
Look for chaffed, pierced, pinched, or partially broken wires and broken, bent, pushed
out, spread, corroded, or contaminated terminals.
The following additional checks may assist you in identifying a possible intermittent
problem.
Reconnect any disconnected components and harness connector.
WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNI-
TION ON, THEN RECONNECT THE BATTERY.
With the DRBIII

t monitor active codes as you work through the following steps.

WARNING: TO AVOID PERSONAL INJURY OR DEATH, MAINTAIN A SAFE
DISTANCE FROM ALL AIRBAGS WHILE PERFORMING THE FOLLOWING
STEPS.
Wiggle the wiring harness and connectors of the related airbag circuit or component.
If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop
to stop.
IF only stored codes return continue the test until the problem area has been isolated
In the previous steps you have attempted to recreate the conditions responsible for
setting active DTC in question.
Are any ACTIVE DTCs present?

All

Yes

→ Select appropriate symptom from Symptom List.

No

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

vehicle to customer.

Symptom:

PASSENGER AIRBAG OFF INDICATOR CIRCUIT SHORT TO
GROUND

When Monitored and Set Condition:

PASSENGER AIRBAG OFF INDICATOR CIRCUIT SHORT TO GROUND

When Monitored:

When the ignition is on, the ACM monitors the PAB Indicator Driver

circuit for voltage on the PAB Off indicator circuit.

Set Condition:

The code will set if the ACM cannot detect voltage on the PAB Indicator

Driver circuit.

POSSIBLE CAUSES

IGNITION SWITCH RUN - START CIRCUIT OPEN

FUSE OPEN

ACM, PAB OFF INDICATOR CIRCUIT SHORTED

FUSED RUN-START CIRCUIT SHORTED TO GROUND

PAB OFF INDICATOR DRIVER CIRCUIT SHORTED TO GROUND

PAB OFF INDICATOR INTERNAL SHORT

INDICATOR DISCONNECTED

FUSED IGNITION SWITCH OUTPUT RUN-START CIRCUIT OPEN

PASSENGER AIRBAG INDICATOR DRIVER CIRCUIT OPEN

PASSENGER ON - OFF INDICATOR OPEN

STORED CODE OR INTERMITTENT CONDITION
