Module Not Configured For PAB Off Switch

MODULE NOT CONFIGURED FOR PAB OFF SWITCH

WHEN MONITORED
When the Occupant Restraint Controller (ORC) is not configured for a Passenger Airbag ON - OFF switch, the ORC monitors the Passenger Airbag On - Off Switch inputs to determine if a switch is present.

SET CONDITION
The code will set, if the ORC is not configured for a Passenger Airbag ON - OFF switch but detects that a switch is connected to the module.

POSSIBLE CAUSES
- ORC not configured for PAB on - off switch
- (G104) PAB indicator driver circuit shorted to ground
- (R106) PAB mux switch sense circuit shorted to ground
- (R106) PAB mux switch sense circuit shorted to (R104) PAB mux switch return circuit
- Occupant restraint controller (ORC)

Diagnostic Test

1. DETERMINE ACTIVE OR STORED DTC
Turn the ignition on.

NOTE:
- Ensure that the battery is fully charged.
- For the purpose of this test, the AECM and ACM modules will be referred to as an ORC.
- 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 9

2. CHECKING EQUIPMENT
Inspect the vehicle for a Passenger Airbag On - Off Switch located in the center of the instrument panel.

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

YES: Go To 3
NO: Go To 4

3. ORC NOT CONFIGURED FOR PAB ON - OFF SWITCH
Select Restraints, Airbag, and then Miscellaneous from the DRBIII(R) menu.
Follow DRBIII(R) instructions to verify PAB On - Off Switch configuration.

Q: Does the DRBIII(R) indicate that the ORC is configured for a PAB On - Off Switch?

YES: Go To 8
NO: Follow the DRBIII(R) instructions to configure the Occupant Restraint Controller to support the Passenger Airbag Switch On-Off Switch. Perform ORC VERIFICATION TEST - VER 1. Occupant Restraint Controller (ORC) Verification Test

4. VERIFY CIRCUITS
Inspect vehicle for Passenger Airbag On - Off Switch wiring at the ORC connector.

NOTE: Some vehicles may have the wiring for the Passenger Airbag On - Off Switch but have no switch.

Q: Is this vehicle equipped with Passenger Airbag On - Off Switch wiring?

YES: Go To 5
NO: Go To 8

5. (G104) PAB INDICATOR DRIVER CIRCUIT SHORTED TO GROUND

WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNITION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BEFORE PROCEEDING.




Disconnect the Occupant Restraint Controller C1 connector.

NOTE: Check connectors - Clean and repair as necessary.

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.

Connect the appropriate Load Tool Adaptor to the Occupant Restraint Controller connector.
Measure the resistance of the (G104) Passenger Airbag Indicator Driver circuit between ground and the ORC Adaptor.

Q: Is the resistance below 10K ohms?

YES: Repair the (G104) Passenger Airbag Indicator Driver circuit for a short to ground. Perform ORC VERIFICATION TEST - VER 1. Occupant Restraint Controller (ORC) Verification Test
NO: Go To 6

6. (R106) PAB MUX SWITCH SENSE CIRCUIT SHORTED TO GROUND




Measure the resistance of the (R106) Passenger Airbag MUX Switch Sense circuit between ground and the ORC Adaptor.

Q: Is the resistance below 10K ohms?

YES: Repair the (R106) Passenger Airbag MUX Switch Sense circuit for a short to ground. Perform ORC VERIFICATION TEST - VER 1. Occupant Restraint Controller (ORC) Verification Test
NO: Go To 7

7. (R106) PAB MUX SWITCH SENSE CIRCUIT SHORTED TO (R104) PAB MUX SWITCH RETURN CIRCUIT




Measure the resistance between the (R106) Passenger Airbag MUX Switch Sense circuit and the (R104) Passenger Airbag MUX Switch Return circuit at the ORC Adaptor.

Q: Is the resistance below 10K ohms?

YES: Repair the (R106) Passenger Airbag MUX Switch Sense circuit for a short to the (R104) Passenger Airbag MUX Switch Return circuit Perform ORC VERIFICATION TEST - VER 1. Occupant Restraint Controller (ORC) Verification Test
NO: Go To 8

8. OCCUPANT RESTRAINT CONTROLLER (ORC)

WARNING:
- TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNITION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BEFORE PROCEEDING.
- 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
.

If there are no possible causes remaining, view repair.

Repair
Replace the Occupant Restraint Controller (ORC). Perform ORC VERIFICATION TEST - VER 1. Occupant Restraint Controller (ORC) Verification Test

9. CHECKING STORED OR INTERMITTENT CODES
With the scan tool, record and erase all DTC's from all Airbag Modules.
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 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: 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.

Q: Are any ACTIVE DTCs present?

YES: Select the appropriate diagnostic procedure.
NO: No problem found at this time. Erase all codes before returning vehicle to customer.
