Using Scan Tool
WARNING: This page is about a different car, the 1999 Buick Regal and 1999 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
When using scan tool for diagnostics, ABS/TCS-ETS system is disabled by EBCM/EBTCM. ANTI-LOCK indicator will illuminate indicating only normal power assist braking is available. After diagnostics have been completed, disconnect scan tool from Data Link Connector (DLC) and turn ignition off for a least 10 seconds before road testing. This procedure is done to reset EBCM/EBTCM.
- Connect scan tool to Data Link Connector (DLC) located under left side of instrument panel. Follow scan tool manufacturer's instructions to retrieve stored fault codes.
- If multiple codes are displayed, begin diagnosis with code that is displayed first. Diagnose all codes in the order displayed by scan tool.
