Diagnostic Test
- DETERMINE ACTIVE OR STORED DTC NOTE:
Make sure that the battery is fully charged.
NOTE:The scan tool, SRS load tool (special tool #8443A, SRS Load Tool), and DVOM are required to perform the following test.
- Turn the ignition on.
Select ACTIVE or STORED DTC:
ACTIVE DTC
- Go To 2
STORED DTC
- Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Refer to RESTRAINTS SYSTEM INTERMITTENT TEST .
- Turn the ignition on.
- CHECK FOR OPEN DRIVER KNEE BOLSTER AIRBAG CIRCUITS WARNING:
Turn the ignition off disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
- Disconnect the Driver Knee Bolster Airbag harness connector.NOTE:
Check connectors - Clean and repair as necessary.
- Connect the (special tool #8443A, SRS Load Tool) to the (special tool #8443-8, Jumper, SRS Load) to the Driver Knee Bolster Airbag harness connector.WARNING:
Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
- With the scan tool, read the active ORC DTCs.
Does the scan tool display: B0116-1B FRONT DRIVER KNEE BAG - CIRCUIT RESISTANCE ABOVE THRESHOLD - DTC?
Yes
- Go To 3
No
- Replace the Driver Knee Bolster Airbag in accordance with the service information. Refer to AIR BAG, KNEE BLOCKER, REMOVAL .
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
- Disconnect the Driver Knee Bolster Airbag harness connector.
- CHECK (R11) DRIVER KNEE BLOCKER SQUIB LINE 1 CIRCUIT FOR AN OPEN WARNING:
Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
- Disconnect the (special tool #8443A, SRS Load Tool) from the (special tool #8443-8, Jumper, SRS Load) from the Driver Knee Bolster Airbag harness connector.
- Disconnect the ORC harness connectors.NOTE:
Check connectors - Clean and repair as necessary.
NOTE:Probing of the circuit cavities at the ORC Module body harness connectors is only to be done with an approved test lead from the test lead 10159-6 (special tool #10159, Test Leads, Dedicated), or a comparable test lead to prevent vehicle wiring harness connector damage during diagnostic procedures.
- Connect the test probes to the appropriate ORC harness connector terminal(s).
- Measure the resistance of the (R11) Driver Knee Blocker Squib Line 1 circuit between the Driver knee Bolster Airbag harness connector terminal 2 and the appropriate cavity.
Is the resistance below 1.0 Ohm?
Yes
- Go To 4
No
- Repair the (R11) Driver Knee Blocker Squib Line 1 circuit for an open in accordance with the service information.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
- CHECK (R9) DRIVER KNEE BLOCKER SQUIB LINE 2 CIRCUIT FOR AN OPEN
- Measure the resistance of the (R9) Driver Knee Blocker Squib Line 2 circuit between the Driver Knee Bolster Airbag harness connector and the appropriate cavity.
Is the resistance below 1.0 Ohm?
Yes
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. Failure to follow these instructions may result in possible serious or fatal injury.
- Replace the ORC in accordance with the service information. Refer to MODULE, OCCUPANT RESTRAINT CONTROLLER, REMOVAL .
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
No
- Repair the (R9) Driver Knee Blocker Squib Line 2 circuit for an open in accordance with the service information.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
- Measure the resistance of the (R9) Driver Knee Blocker Squib Line 2 circuit between the Driver Knee Bolster Airbag harness connector and the appropriate cavity.
