Question "I have a 1992 Cadillac Touring de Ville. The engine is 4.9L. I have many troubles with the warning light, "vehicle service soon" This Light some times is on, other times is off. I check brakes, fluids, chassis grease. Please tell me what the problem is.
Best regards
Answer To check for CODES:
1. Turn ignition switch ON. Do NOT start the engine.
2. Simultaneously push and hold the OFF and WARMER buttons on your climate control panel for 3 seconds and release them.
3. On the display you will see LETTERS & NUMBERS appearing and the display will stop at .7.0.
4. Tell me EXACTLY everything as if you were video taping the display that you see on the display.
