How do you reset the maintenance required light on a 1990 Dodge Grand Caravan 3.3 liter engine?

Answer 1

From 1989 on, the maintenance required light is turned off using a DRB-II Scan tool that most professional shops and the dealer have.

Or, if you are Cheap,,,er, I mean Cost Effective orientated, like me and wish

to spend the cost of a service call bill for other things, a strategically

placed piece of black electrical tape makes the light "disappear" too.

if you disconnect your battery cables and leave them disconnected overnight, the check engine or maintenance light usually goes off unless there is really something going on in your vehicles system. i did this for my van twice and it works just fine. i was told that the maintenance lights come on at different mileage intervals just as a vehicle precaution for maintenance, and usually there is nothing wrong.
