Displaying & Reading Trouble Codes

Some Diagnostic Trouble Codes (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 the air bag diagnostic monitor's Non-Volatile Random Access Memory (NVRAM) under these circumstances. Correction of the charging system problem will eliminate the DTC.

- 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 DTCs.

(1). Locate the air bag diagnostic service connector containing Circuit 631 (T/R). This is a grey connector under the glove compartment.

(2). With the ignition key OFF, short Circuit 631 to the ground contained in the service connector or another good ground.

(3). Turn the ignition key to RUN and observe the six second air bag indicator prove-out.

(4). Within two seconds after indicator prove-out, remove the short on Circuit 631.

(5). Stored DTCs will be displayed. After service, repeat steps 1-4 and clean the DTCs cleared using the DTC Clearing Procedure .
