Retrieving Codes
- Drive vehicle at 6 MPH (10 km/h) for at least 20 seconds. When system fault is detected, ABS warning light will illuminate.
- Access ABS Data Link Connector (DLC). See Fig 1 . Turn ignition off. Connect diagnostic terminal to terminal "L" at DLC. Turn ignition on. Determine Diagnostic Trouble Code (DTC) by counting number of times ABS warning light flashes. Up to 3 codes can be stored at a time, with the most recent code displayed first.
- ABS light first flashes DTC 11, which is the start code. DTCs will then be flashed. See illustration for example. See Fig 2 . After codes are flashed, start DTC 11 will again be displayed and codes repeated. Perform appropriate DTC test under TESTING . See ABS DIAGNOSTIC TROUBLE CODES table.
