TION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BE-
FORE PROCEEDING.
Disconnect the Passenger Airbag connector(s).
NOTE: Check connectors - Clean and repair as necessary.
WARNING: TO AVOID PERSONAL INJURY OR DEATH, DO NOT PLACE AN
INTACT UNDEPLOYED AIRBAG FACE DOWN ON A HARD SURFACE, THE
AIRBAG WILL PROPEL INTO THE AIR IF ACCIDENTALLY DEPLOYED.
Connect the Load Tool to the Passenger Airbag connector(s).
WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN IGNITION
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 OPEN?
All
Yes
→ Go To 3
No
→ Replace the Passenger Airbag in accordance with the Service
Information.
Perform AIRBAG VERIFICATION TEST - VER 1.

WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNI-
TION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BE-
FORE PROCEEDING.
Disconnect the Load Tool from the Passenger Airbag connector(s).
Disconnect the Airbag Control module connector(s).
NOTE: Check connectors - Clean and repair as necessary.
Connect the Load Tool ACM Adaptor to the Airbag Control Module connector(s).
Measure the resistance of the Passenger Squib 1 Line 1 and Line 2 circuit between
the ACM Adaptor and the Passenger Airbag connector.
Is the resistance below 1.0 ohms on both circuits?
All
Yes
→ Go To 4
No
→ Repair open or high resistance in Passenger Squib 1 Line 1 or
Line 2 circuits.
Perform AIRBAG VERIFICATION TEST - VER 1.

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

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 circuits, rotate the steering wheel from stop to stop.
You have just attempted to simulate the condition that initially set the trouble code
message.
Did the DTC become active?
All
Yes
→ Select appropriate symptom from Symptom List.
No
→ No problem found at this time. Erase all codes before returning
vehicle to customer.
