B1301 - PASSENGER KNEE BLOCKER AIRBAG SHORT TO BATTERY





- When Monitored: 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 abnormally high voltage in the Passenger Knee Blocker Airbag Squib circuits.





Diagnostic Test

1. WITH THE SCAN TOOL, READ DTCs

NOTE: When reconnecting the Airbag System components, the ignition must be turned off and the battery must be disconnected.

NOTE: Ensure the battery is fully charged.

Turn the ignition on.

With the scan tool, select ACTIVE or STORED DTCs.

Is the DTC ACTIVE?

Yes

- Go to 2

No

- Go to 5

2. WITH THE SCAN TOOL, READ ACTIVE DTCs

WARNING: Turn the ignition off, disconnect the battery and wait two minutes before proceeding.

WARNING: Do not place an intact undeployed airbag face down on a hard surface; the airbag will propel into the air if accidentally deployed, and could result in serious or fatal injury.

Disconnect the Passenger Knee Blocker Airbag.

NOTE: Check connectors - Clean/repair as necessary.

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

WARNING: TURN THE IGNITION ON, THEN RECONNECT THE BATTERY.

With the scan tool, read the active Airbag DTCs.

Does the scan tool display an active Driver Knee Blocker Airbag DTC?

Yes

- Go to 3

No

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

3. MEASURE THE VOLTAGE OF THE PASSENGER KNEE BLOCKER SQUIB LINE 1 CIRCUIT





WARNING: Turn the ignition off, disconnect the battery and wait two minutes before proceeding.

Disconnect the ORC harness connector.

NOTE: Check connectors - Clean/repair as necessary.

WARNING: TURN THE IGNITION ON, THEN RECONNECT THE BATTERY.

Measure the voltage of the Passenger Knee Blocker Squib Line 1 circuit at the Airbag 2 - wire connector.

Is voltage present?

Yes

- Repair the Passenger Knee Blocker Squib Line 1 circuit for a short to voltage.
- Perform AIRBAG VERIFICATION TEST. Airbag System Verification Test

NOTE: When reconnecting the Airbag System components, the ignition must be turned off and the battery must be disconnected.

No

- Go to 4

4. MEASURE THE VOLTAGE OF THE PASSENGER KNEE BLOCKER SQUIB LINE 2 CIRCUIT





With the ignition on.

Measure the voltage of the Passenger Knee Blocker Squib Line 2 circuit at the Airbag 2 - wire connector.

Is voltage present?

Yes

- Repair the Passenger Knee Blocker Squib Line 2 circuit for a short to voltage.
- Perform AIRBAG VERIFICATION TEST. Airbag System Verification Test

NOTE: When reconnecting the Airbag System components, the ignition must be turned off and the battery must be disconnected.

No

- Replace the Occupant Restraint Controller.

WARNING: If the occupant restraint controller is dropped at any time, it must be replaced.

- Perform AIRBAG VERIFICATION TEST. Airbag System Verification Test

5. WITH THE SCAN TOOL, READ DTCs

NOTE:
Ensure the battery is fully charged.

With the Scan Tool, record and erase all Restraint System DTCs.

All active codes must be resolved before diagnosing any stored codes.

Maintain a safe distance from all airbags while performing the following steps.

With the Scan Tool, monitor active codes as you work through the system.

NOTE: Read the DTCs with the Passenger Airbag On/Off Switch in both switch positions.

Wiggle the wiring harness and connectors of the appropriate airbag system and rotate the steering wheel from stop to stop.

NOTE: Check connectors - Clean/repair as necessary.

You have just attempted to simulate the condition that initially set the trouble code message.

The following additional checks may assist you in identifying a possible intermittent problem:
- Visually inspect related wire harness connectors. Look for broken, bent, pushed out, spread, corroded, or contaminated terminals.
- Visually inspect the related harnesses. Look for chafed, pierced, pinched or partially broken wire.
- Refer to any Wiring Diagrams that may apply.

Did the DTC become ACTIVE?

Yes

- Go to 2

No

- The condition that caused this DTC to set is currently not present.
- Perform AIRBAG VERIFICATION TEST. Airbag System Verification Test
