Diagnostic Test

WARNING: This page is about a different variant/trim than selected.

DETERMINE ACTIVE OR STORED DTC
NOTE:
Make sure that the battery is fully charged.

NOTE:
The scan tool, (special tool #8443A, SRS Load Tool), and DVOM are required to perform the following test.
1. 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 .
CHECK FOR SHORTED 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.
1. Disconnect the Driver Knee Bolster Airbag harness connector.
  WARNING:
  Do not place an intact non-deployed airbag face down on a hard surface, the airbag propels into the air if accidentally deployed. Failure to follow these instructions may result in possible serious or fatal injury.
  
  NOTE:
  Check connectors - Clean and repair as necessary.
2. 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.
3. With the scan tool, read the active ORC DTCs.
  Does the scan tool display: B0116-11-FRONT DRIVER KNEE BAG - CIRCUIT SHORT TO GROUND - 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 .
CHECK (R11) DRIVER KNEE BLOCKER SQUIB LINE 1 CIRCUIT OR (R9) DRIVER KNEE BLOCKER SQUIB LINE 2 CIRCUIT FOR A SHORT TO GROUND
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.
1. Disconnect the (special tool #8443A, SRS Load Tool) and the (special tool #8443-8, Jumper, SRS Load) from the Driver Knee Bolster Airbag harness connector.
2. 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 a approved test lead from the (special tool #10159, Test Leads, Dedicated), test lead 10159-6. Or a comparable test lead to prevent vehicle wiring harness connector damage during diagnostic procedures.
3. Connect the test probes to the appropriate ORC harness connector terminal(s).
4. Measure the resistance between ground and the (R11) Driver Knee Blocker Squib Line 1 circuit at the appropriate terminals.
5. Measure the resistance between ground and the (R9) Driver Knee Blocker Squib Line 2 circuit at the appropriate terminals.
  Is the resistance below 10K Ohms on either circuit?
  
  Yes
  - Repair the (R11) Driver Knee Blocker Squib Line 1 or (R9) Driver Knee Blocker Squib Line 2 circuits for a short to ground in accordance with the Service Information.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
