Retrieving Codes
NOTE:
Perform procedures for appropriate FUNCTIONAL TEST under TROUBLE SHOOTING CHARTS .
- If using Tech 1 for retrieving codes, go to step 3). If using ANTI-LOCK light for retrieving codes, turn ignition on. Using a jumper wire, connect terminal "H" to terminal "A" in Data Link Connector (DLC). See Fig 1. System will repeat trouble code(s) as long as DLC terminals are connected.NOTE: The DLC may also be referred to as the Assembly Line Data Link (ALDL) connector. These 2 terms may be used interchangeably.
- Trouble codes will be displayed by a flashing ANTI-LOCK warning light. As an example, Code 25 would be displayed by ANTI-LOCK warning light flashing 2 times, followed by a pause, then flashing 5 more times. See 4WAL FAULT CODES table for diagnosis. If no fault codes are present, see 4WAL SYMPTOM DIAGNOSIS table.
- Turn ignition off. Connect Tech 1 to DLC. Access 4WAL brake trouble codes using Tech 1. Repair trouble codes in order they appear. See 4WAL FAULT CODES table for diagnosis. If no fault codes are present, see 4WAL SYMPTOM DIAGNOSIS table.
