B10D4

B10D4-TRIGGER CIRCUIT 0 - CIRCUIT LOW ON UNCONFIGURED POSITION - PIN 33/34 [ZH]

For a complete wiring diagram Consult Diagrams/Electrical.

- When Monitored:
The Occupant Restraint Controller (ORC) monitors the input and output terminals during the module initialization.

- Set Condition:
Based on the pre-programmed module configuration the DTC will set if the module detects a short to ground on terminals 33 and 34.





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 DTC.
Does the scan tool display active DTC: B10D4-TRIGGER CIRCUIT 0 - CIRCUIT LOW ON UNCONFIGURED POSITION - PIN 33/34 [ZH]?

Yes

- Go To2

No

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

2. INSPECT CIRCUIT IN QUESTION FOR CONNECTOR DAMAGE
WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

Ensure all harness connectors are properly seated.
Inspect the circuits in question for connector terminals bent, corroded, or contaminated terminals.
Were any of the above conditions present?

Yes

- Repair as necessary.
- Perform *AIRBAG VERIFICATION TEST. Airbag System Verification Test

No

- Go to 3

3. INSPECT CIRCUIT IN QUESTION FOR CONNECTOR DAMAGE
WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

Inspect the ORC circuits in question for connector terminals bent, corroded, or contaminated terminals.
Were any of the above conditions present?

Yes

WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take proper precautions could result in accidental airbag deployment and serious or fatal injury.
Replace the Occupant Restraint Controller (ORC).
- Perform *AIRBAG VERIFICATION TEST. Airbag System Verification Test

No

- Go to 4

4. OCCUPANT RESTRAINT CONTROLLER (ORC) CODING
Measure the resistance of the terminal in question between ORC Load Tool 8443-33 and ground.
Measure the resistance between the terminal in question at the ORC Load Tool 8443-33.
Is the resistance below 1.0 ohm for either measurement?

Yes

- Repair or replace he circuits in question.
- Perform *AIRBAG VERIFICATION TEST. Airbag System Verification Test

No

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