WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNI-
TION ON, THEN RECONNECT THE BATTERY.
With the DRBIII
t, read the active Airbag Control Module DTC’s.
Does the DRBIII
t show PASSENGER SQUIB 1 CIRCUIT SHORT?
All
Yes
→ Go To 3
No
→ Replace the Passenger Airbag in accordance with the Service
Information.
Perform __AIRBAG VERIFICATION TEST - VER 1.

Disconnect the Airbag Control Module connector(s).
NOTE: Check connectors - Clean and repair as necessary.
Connect the appropriate Load Tool Adapter to the Airbag Control Module connec-
tor(s).
Measure the resistance between Passenger Squib 1 Line 1 and Line 2 circuits at the
Passenger Airbag connector.
Is the resistance below 10K ohms?
All
Yes
→ Repair Passenger Squib 1 Line 1 circuit short to Passenger Squib
1 Line 2 circuit.
Perform __AIRBAG VERIFICATION TEST - VER 1.
No
→ Go To 4

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.
