Trouble Shooting: Notes

Always perform DIAGNOSIS & TESTING  and check for Diagnostic Trouble Codes (DTCs) before performing TROUBLE SHOOTING procedures. Before attempting to diagnose vehicle, ensure ABS warning light is functioning properly. ABS warning light will not illuminate and ABS will not operate if battery voltage is insufficient. Perform TROUBLE SHOOTING procedures on ABS warning light, TCS OFF light and TCS warning light to eliminate unnecessary repairs and/or component replacement.
