Dodge Sprinter. Manual - part 366

TEST

ACTION

APPLICABILITY

Measure the resistance of the Airbag Warning Lamp Driver circuit between the
Airbag Control Module Adaptor and ground.
Is the resistance below 5.0 ohms?

All

Yes

→ Repair the Airbag Warning Indicator Driver circuit shorted to

ground.
Perform AIRBAG VERIFICATION TEST - VER 1.

→ Go To 7

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 the Service
Information.
Perform AIRBAG VERIFICATION TEST - VER 1.

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 problem found at this time. Erase all codes before returning

vehicle to customer.
