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: TURN THE IGNITION OFF, DISCONNECT THE BATTERY AND
WAIT TWO MINUTES BEFORE 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: TURN THE IGNITION ON, THEN RECONNECT THE BATTERY.
With the DRBIII

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

WARNING: 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.
