Diagnostic Test

1.TEST FOR INTERMITTENT CONDITION


NOTE: Ensure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.



NOTE: A red X will be next to the module that is not communicating, indicating that the module is not active on the Bus network. A green check indicates that the module is active on the Bus network.



Does the scan tool display a red X next to the module?

Yes
  • Go To 2


No
  • The no response condition is not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring for chafed, pierced, pinched, and partially broken wires and the wiring harness connectors for broken, bent, pushed out, and corroded terminals.

2.(Z913) (Z916) GROUND CIRCUITS OPEN



WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.






Is the resistance below 10k ohms?

Yes
  • Go To 3


No
  • Repair the (Z913) or (Z916) ground circuit for an open.
  • Perform the AIRBAG VERIFICATION TEST - VER 1.

3.(F100) FUSED RUN RELAY OUTPUT CIRCUIT OPEN OR SHORTED



NOTE: Check the TIPM for any ignition related DTCs before proceeding. If set (Refer to 8 - ELECTRICAL/IGNITION CONTROL - DIAGNOSIS AND TESTING).


WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.




Does the test light illuminate brightly?

Yes
  • Go To 4


No
  • Repair the (F100) Fused Run Relay Output circuit for an open or short.
  • Perform the AIRBAG VERIFICATION TEST - VER 1.

4.(F201) FUSED RUN/START RELAY OUTPUT CIRCUIT OPEN OR SHORTED





Does the test light illuminate brightly?

Yes
  • Go To 5


No
  • Repair the (F201) Fused Run/Start Relay Output circuit for an open or short.
  • Perform the AIRBAG VERIFICATION TEST - VER 1.

5.(D65) CAN C BUS (+) CIRCUIT OPEN







Is resistance below 5.0 ohms?

Yes
  • Go To 6


No
  • Repair the (D65) CAN C Bus (+) circuit for an open.
  • Perform the AIRBAG VERIFICATION TEST - VER 1.

6.(D64) CAN C BUS (-) CIRCUIT OPEN





Is resistance below 5.0 ohms?

Yes
  • Replace the Occupant Restraint Controller Module in accordance with the service information.
  • Perform the AIRBAG VERIFICATION TEST - VER 1.


No
  • Repair the (D64) CAN C Bus (-) circuit for an open.
  • Perform the AIRBAG VERIFICATION TEST - VER 1.
