ORC-Driver Squib 1 Circuit High







B1101-ORC-DRIVER SQUIB 1 CIRCUIT HIGH [ZH]





For a complete wiring diagram Consult Diagrams/Electrical.

- When Monitored:
With the ignition on.

- Set Condition:
The Occupant Restraint Controller (ORC) monitors the resistance of the Driver Squib 1 circuits. The ORC will set this DTC if it detects an open or high resistance on the Driver Squib 1 circuits.





Diagnostic Test

1. DETERMINE ACTIVE OR STORED DTC

NOTE: Ensure that the battery is fully charged.

Turn the ignition on.
With the scan tool, read ORC DTCs
Does the scan tool display active DTC: B1101-ORC-DRIVER SQUIB 1 CIRCUIT HIGH [ZH]?

Yes

- Go To 2

No

- Go To 6

2. CHECK FOR OPEN SQUIB CIRCUITS IN DRIVER AIRBAG
WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

Disconnect the Driver Airbag Squib connectors.

WARNING: To avoid serious or fatal injury, 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 Driver Airbag Squib connectors.

WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.

With the scan tool, read ORC DTCs.
Does the scan tool display active DTC: B1101-ORC-DRIVER SQUIB 1 CIRCUIT HIGH [ZH]?

Yes

- Go To 3

No

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

- Replace the Driver Airbag.
- Perform *AIRBAG VERIFICATION TEST. Airbag System Verification Test

3. CHECK CLOCKSPRING SQUIB CIRCUITS FOR AN OPEN
WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

Disconnect the 8443 Load Tool and Jumper from the Driver Airbag Squib connectors.
Disconnect the Clockspring connector.

NOTE: Check connectors - Clean and repair as necessary.

Connect the 8443 Load Tool and appropriate Jumper to the Clockspring connector.

WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.

With the scan tool, read ORC DTCs.
Does the scan tool display active DTC: B1101-ORC-DRIVER SQUIB 1 CIRCUIT HIGH [ZH]?

Yes

- Go To 4

No

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

- Replace the Clockspring.
- Perform *AIRBAG VERIFICATION TEST. Airbag System Verification Test

4. CHECK DRIVER SQUIB 1 LINE 2 CIRCUIT FOR AN OPEN




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

Disconnect the 8443 Load Tool and Jumper from the Clockspring connector.
Disconnect the ORC connectors.

NOTE: Check connectors - Clean and repair as necessary.

Connect the ORC 8443-33 Adaptor to the ORC connector.
Measure the resistance of the Driver Squib 1 Line 2 circuit between the Clockspring connector and the ORC 8443-33 Adaptor.
Is the resistance below 1.0 ohm?

Yes

- Go To 5

No

- Repair the Driver Squib 1 Line 2 circuit for an open.
- Perform *AIRBAG VERIFICATION TEST. Airbag System Verification Test

5. CHECK DRIVER SQUIB 1 LINE 1 CIRCUIT FOR AN OPEN




Measure the resistance of the Driver Squib 1 Line 1 circuit between the Clockspring connector and the ORC Load Tool Adaptor.
Is the resistance below 1.0 ohm?

Yes

WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions can result in accidental airbag deployment and serious or fatal injury.

- Replace the ORC.
- Perform *AIRBAG VERIFICATION TEST. Airbag System Verification Test

No

- Repair the Driver Squib 1 Line 1 circuit for an open.
- Perform *AIRBAG VERIFICATION TEST. Airbag System Verification Test

6. CHECKING STORED OR INTERMITTENT CODES
NOTE: Diagnose and repair all active codes before diagnosing stored codes.

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

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

Using the wiring diagram/schematic as a guide, inspect the related wiring and connectors for chafed, pierced, pinched, and partially broken wires, and for broken, bent, pushed out, corroded, and contaminated terminals. Repair as necessary.
Reconnect all disconnected components and harness connectors.

WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.

With the scan tool, monitor for active codes while performing the following:
- Wiggle the wiring harness and connectors of the related airbag circuit.
- Rotate the steering wheel from stop to stop.
- Continue the test until either a code becomes active or the problem area is isolated.

In the previous steps you have attempted to recreate the conditions responsible for setting the DTC in question / causing the intermittent condition.
Are any ACTIVE DTCs present?

Yes

- Diagnose and repair the DTC(s).

No

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