If an air bag DTC has been reported on a vehicle but is not currently flashing, this may be due to two reasons: [LIST] [*]A charging system concern has been identified by the diagnostic monitor and a DTC 12 indicated. DTC 12 will not be stored in the air bag diagnostic monitor's Non-Volatile Random Access Memory (NVRAM) under these circumstances. [COLOR=rgb(184, 49, 47)]Correction of the charging system problem will eliminate the DTC.[/COLOR] [*]An intermittent fault has occurred and the fault is no longer present. The diagnostic monitor may be programmed to flash "intermittent" DTCs 61-85 that are stored in NVRAM. Use the following procedure to access the stored DTC(s). [LIST=1] [*]Locate the air bag diagnostic service connector containing Circuit 631 (T/R). This is a grey connector under the glove compartment. [*]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. After service, repeat steps 1-4 and clean the DTCs. [/LIST] [/LIST] It appears you could have a issue in the charging sytem somewhere that needs to be resolved. (I advise a alternator ripple test to check the integrity of the working condition of the alternator and a Battery check) [COLOR=rgb(247, 218, 100)]Check this first:[/COLOR] [LIST] [*][COLOR=rgb(247, 218, 100)][B]Loss of ignition voltage at Pin 6 of the air bag diagnostic monitor[/B].[/COLOR] [/LIST] [COLOR=rgb(247, 218, 100)]The air bag diagnostic monitor requires power at Pin 6 to energize the air bag indicator circuit properly.
