B10FD-AIRBAG WARNING INDICATOR CIRCUIT HIGH [ZH]




For a complete wiring diagram Consult Diagrams/Electrical.

- When Monitored:
With the ignition on. The Occupant Restraint Controller (ORC) monitors the status of the Airbag Warning Indicator Driver circuit.

- Set Condition:
The DTC will set if the Airbag Warning Indicator Driver circuit is shorted to voltage.





Diagnostic Test

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

NOTE: Ensure that the battery is fully charged.

With the scan tool, read ORC DTCs.
Does the scan tool display active DTC: B10FD-AIRBAG WARNING INDICATOR CIRCUIT HIGH [ZH]?

Yes

- Go To 2

No

- Go To 3

Diagnostic Test

2. MEASURE AIRBAG WARNING INDICATOR DRIVER CIRCUIT VOLTAGE




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

Disconnect the Instrument Cluster harness connector.

NOTE: Check connectors - Clean/repair as necessary.

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

Measure the voltage of the Airbag Warning Indicator Driver circuit at the Instrument Cluster harness connector.
Is the voltage above 11 volts?

Yes

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

- Repair the Airbag Warning Indicator Driver circuit for a short to voltage.
- 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

3. CHECKING STORED OR INTERMITTENT CODES
With the Scan Tool, record and erase all DTCs from all Airbag modules.
If equipped with Passenger Airbag On-Off switch, read the DTCs in all switch positions.
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 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 active DTC in question.
Are any ACTIVE DTCs present?

Yes

- Diagnose and repair the DTC(s).

No

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