Entering On-Board Diagnostics
NOTE:
Intermittent history codes do not illuminate Amber ANTI-LOCK warning light. DO NOT use ABS/TCS fault codes table for intermittent problems. See INTERMITTENTS
.
NOTE:
Data Link Connector (DLC) may also be referred to as Assembly Line Diagnostic Link (ALDL) connector.
- Connect Tech 1 scan tool to DLC. Connector is located under left side of instrument panel, right of steering column. Follow scan tool manufacturer's instructions to retrieve stored fault codes.
- If multiple codes are displayed, begin diagnosis with code that is displayed first. See ABS/TCS FAULT CODES table. Diagnose all codes in the order displayed by Tech 1 scan tool.
- After repairs are complete, clear all codes. Follow scan tool manufacturer's instructions to clear stored fault codes.
