QuestionQUESTION: The "Service Vehicle Soon" idiot light comes on after 3 miles of driving and stays on. What does this mean ?What systems does this pertain to? The vehicle is a 1991 Cadillac Coupe Deville with 72 thousand miles on it.It hasn't been driven much over the last seven months due to family illness and being laid off work.
Thanks, Larry
ANSWER: OK perform this test:
1. Turn the ignition switch to the ON position. 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 ..E and or .E.E along with NUMBERS (codes)appearing such as E45 or maybe EE45 or some other combination.
4. When the display stops at .70, Turn OFF the ignition.
5. Tell me EXACTLY what displays on the display as if you were video taping the display after you release the OFF and WARMER (^) buttons on your climate control panel for 3 seconds.
6. Turn ignition OFF.
