Diagnostic Trouble Code Retrieval
Some DTCs for intermittent problems (61-85) may not automatically flash on the air bag indicator and may require retrieval. If an air bag DTC has been reported on a vehicle but is not currently flashing, this may be due to two reasons:
- A charging system concern has been identified by the diagnostic monitor and a DTC 12 indicated. DTC 12 will not be stored in NVRAM under these circumstances. Correction of the charging system problem will eliminate the DTC.
- The diagnostic monitor may not be programmed to automatically flash "intermittent" DTCs 61-85 that are stored in NVRAM. Use the following procedure to access the stored DTC(s):
- With the ignition key OFF, short Circuit 631 to the ground contained in the service connector or another good ground.
- Turn the ignition key to RUN and observe the six second air bag indicator prove out.
- Within two seconds after indicator prove out, remove the short on Circuit 631.
- Stored DTCs will be displayed. The DTCs may be cleared using the DTC Clearing Procedure.
