B1B0C-PASSENGER AIRBAG SQUIB 2 CIRCUIT LOW





For a complete wiring diagram refer to Diagrams/Electrical.

- When Monitored:

With the ignition on, the ORC monitors the resistance of the Passenger Squib 2 circuits.

- Set Condition:

The ORC has detected low resistance between the Passenger Squib 2 circuits.





Diagnostic Test

1.DETERMINE ACTIVE OR STORED DTC

NOTE: Ensure the battery is fully charged.

NOTE: The Scan Tool, SRS Airbag Load Tool MRL 8443 and DVOM are required to perform the following test.

Select Active or Stored DTC.

Is the DTC active or stored?

ORC - ACTIVE DTC

- Go To 2

ORC - STORED DTC

- Go To 5

2.PASSENGER AIRBAG SHORTED





WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

Disconnect the Passenger Airbag Squib connector(s).

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.

NOTE: Check connectors - Clean and repair as necessary.

Connect the 8443 Load Tool and appropriate Jumper to the Passenger Airbag connector(s).

WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.

With the scan tool, read the active Occupant Restraint Controller DTCs.

Does the scan tool display PASSENGER AIRBAG SQUIB 2 CIRCUIT LOW?

Yes

- Go to 3

No

- Replace the Passenger Airbag.
- Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1. Airbag System Verification Test

3.(R64) PASSENGER SQUIB 2 LINE 1 OR (R62) PASSENGER SQUIB 2 LINE 2





WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

Disconnect the 8443 Load Tool and Jumper from the Passenger Airbag harness connector(s).

Disconnect the ORC harness connector(s).

NOTE: Check connectors - Clean and repair as necessary.

Connect the 8443 Load Tool ORC Adaptor to the ORC C1 harness connector.

Measure the resistance of the (R64) Passenger Squib 2 Line 1 circuit between the Passenger Airbag Squib harness connector and ground.

Measure the resistance of the (R62) Passenger Squib 2 Line 2 circuits between the Passenger Airbag Squib harness connector and ground.

Is the resistance below 10K ohms on either circuit?

Yes

- Repair the (R64) Passenger Squib 2 Line 1 and or (R62) Passenger Squib 2 Line 2 shorted to ground.
- Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1. Airbag System Verification Test

No

- Go to 4

4.OCCUPANT RESTRAINT CONTROLLER

WARNING: If the Occupant Restraint Controller is dropped at any time, it must be replaced. Failure to take the proper precautions can 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.
- Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1. Airbag System Verification Test

5.STORED ORC DTC

With the scan tool, record and erase all DTCs from all Airbag System 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 chafed, 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.

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.

Are any ACTIVE DTCs present?

Yes

- Select appropriate symptom from Symptom List.

No

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