B1301
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
