B1300-ORC-PASSENGER KNEE BOLSTER SQUIB CIRCUIT LOW [ZH]





- When Monitored:
With ignition on. The Occupant Restraint Controller (ORC) monitors the resistance of the Passenger Knee Blocker Airbag Squib Circuits.

- Set Condition:
The Occupant Restraint Controller (ORC) has detected low resistance in the Passenger Knee Blocker Airbag Squib Circuits.





Diagnostic Test

1. VERIFY THAT ORC DTC B1300 IS ACTIVE
NOTE: Ensure the battery is fully charged.

Turn the ignition on.
With the scan tool, read ORC DTCs.

Yes

- Go To 2

No

- Go To 5

2. WITH THE SCAN TOOL, READ ACTIVE DTCs
WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

NOTE: Check connectors - Clean/repair as necessary.

Connect the Load Tool and Jumper to the Passenger Knee Blocker Airbag Squib connector.

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

With the scan, read ORC DTCs.
Does the scan tool display an active DTC: B1300-ORC-PASSENGER KNEE BOLSTER SQUIB CIRCUIT LOW [ZH]?

Yes

- Go To 3

No

- Replace the Passenger Knee Blocker Airbag.
- Perform *AIRBAG VERIFICATION TEST. Airbag System Verification Test

3. CHECK THE PASSENGER KNEE BLOCKER AIRBAG SQUIB LINE 1 CIRCUIT FOR A SHORT TO GROUND




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

Disconnect the ORC harness connector.

NOTE: Check connectors - Clean and repair as necessary.

Connect the Load Tool ORC 8443-33 Adapter to the ORC harness connector.
Measure the resistance of the Passenger Knee Blocker Squib Line 1 circuit and ground.
Is the resistance below 10K ohms?

Yes

- Repair the Passenger Knee Blocker Squib Line 1 circuit.
- Perform *AIRBAG VERIFICATION TEST. Airbag System Verification Test

No

- Go To 4

4. CHECK THE PASSENGER KNEE BLOCKER AIRBAG SQUIB LINE 2 CIRCUIT FOR A SHORT TO GROUND




Measure the resistance of the Passenger Knee Blocker Squib Line 2 circuit and ground.
Is the resistance below 10k ohms?

Yes

- Repair the Passenger Knee Blocker Squib Line 2 circuit.
- Perform *AIRBAG VERIFICATION TEST. Airbag System Verification Test

No

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

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 Occupant Restraint Controller.
- Perform *AIRBAG VERIFICATION TEST. Airbag System Verification Test

5. TEST FOR INTERMITTENT CONDITION
With the scan tool, record and erase all DTCs from all Airbag modules.
If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.

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 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 serious or fatal injury, 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 serious or fatal injury, 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 the active DTC in question.
Does the scan tool display any ACTIVE DTCs?

Yes

- Diagnose and repair the DTC(s).

No

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