RETRIEVING TROUBLE CODES
All Supplemental Restraint Systems ([1][2]SRS) Diagnostic Trouble Codes (DTC)s can be read using "Flash Code" diagnostics. "Flash Code" diagnostics are enabled either by connecting a jumper wire between terminal "TC" and terminal "E1" (ground) on the Data Link Connector (DLC) with the ignition switch in "ACC" or "ON." Grounding terminal "TC" of the DLC pulls the "Diagnosis and Memory Circuits," terminal "B9", of the center sensor assembly low and signals the center sensor assembly to enter "Flash Code" diagnostic display mode.

The center sensor assembly displays DTCs by flashing the air bag indicator (located in the instrument cluster). Each DTC displayed consists of a number of flashes which represent the first digit, a 2.5 second pause, then a number of flashes which represent the second digit of the DTC. Each DTC is flashed once before moving on to the next one. After all DTCs have been displayed, the entire sequence will be repeated until the jumper wire is removed from the DLC or the appropriate command is entered into the TECH 1.

If there are no DTCs present, the center sensor assembly will flash the air bag indicator continuously. This indicates that "Flash Code" diagnostics have been enabled. The center sensor assembly will continue to flash the air bag indicator until the jumper wire is removed from the DLC or the appropriate command is entered into the TECH 1.
