TERY AND WAIT TWO MINUTES BEFORE PROCEEDING.

WARNING: IF THE OCCUPANT RESTRAINT CONTROLLER IS DROPPED AT ANY TIME, IT MUST BE
REPLACED. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG
DEPLOYMENT AND PERSONAL INJURY OR DEATH.

NOTE: When reconnecting airbag system components the Ignition must be turned off and the Battery must
be disconnected.

If there are no possible causes remaining, view repair.

Repair

Replace the Occupant Restraint Controller (ORC) in accordance with the Service Information.

Perform ORC VERIFICATION TEST - VER 1.

CHECKING STORED OR INTERMITTENT CODES

With the Scan Tool, 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 IGNITION OFF, DISCONNECT THE BAT-
TERY 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: TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNITION ON, THEN RECONNECT THE
BATTERY.
With the Scan Tool, 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.

Does the scan tool display any ACTIVE DTCs?

Yes

>> Select the appropriate diagnostic procedure from the Table of Contents in this section.

No

>> No problem found at this time. Erase all codes before returning vehicle to customer.

When Monitored:
When the ignition is on, the Occupant Restraint Controller (ORC) monitors the (G104) Passenger Airbag Indi-
cator Driver circuit for voltage.

•

Set Condition:
The code will set if the ORC senses battery voltage on the (G104) Passenger Airbag Indicator Driver circuit.

Possible Causes

ORC IMPROPERLY CONFIGURED FOR PAB ON - OFF SWITCH

(G104) PAB INDICATOR DRIVER CIRCUIT SHORTED TO BATTERY

(G104) PAB INDICATOR DRIVER CIRCUIT SHORTED TO (F201) FUSED IGNITION SWITCH OUTPUT
(RUN-START) CIRCUIT

PAB ON - OFF INDICATOR SHORTED

ORC, PAB INDICATOR DRIVER CIRCUIT SHORTED TO BATTERY

Diagnostic Test

1.

DETERMINE ACTIVE OR STORED DTC

Turn the ignition on.

NOTE: Ensure that the battery is fully charged.

NOTE: For the purpose of this test, the AECM and ACM modules will be referred to as an ORC.

NOTE: When reconnecting Airbag system components, the ignition must be turned off and the battery must
be disconnected.

SELECT ACTIVE or STORED DTC:

ORC - ACTIVE DTC

Go To 2

ORC - STORED DTC

Go To 7

CHECKING EQUIPMENT

Is this vehicle equipped with a Passenger Airbag On - Off Switch?

Yes

>> Go To 3

No

>> With the Scan TooI in MISCELLANEOUS re-configure the ORC for NO AIRBAG ON/OFF SWITCH.
