How to Reset a Dodge Grand Caravan Computerby Marc Lucas
Your Dodge Grand Caravan, like all vehicles manufactured after 1996, has an on-board diagnostic system. When one of your Grand Caravan's sensors indicates that a system is not operating properly, it will trigger the vehicle's "check engine" light. Sometimes the cause of the error can be as simple as tightening a loose gas cap. In order to verify that the cause of the problem has been fixed, the computer on your Grand Caravan will need to be reset. This process is simple and takes less than 10 minutes.
Pull the hood release lever under the dash to release the hood.
Locate the hood latch under the center of the hood and push the latch to the left. Lift the hood and open completely.
Locate the battery on the driver's side of the engine compartment above the front wheel.
Loosen the bolt on the negative battery cable using the adjustable wrench.
Remove the negative battery cable from the terminal post. If it does not come loose easily, you may need to twist the cable end side to side until the cable end is free of the post.
Reattach the negative battery cable end to the the negative post on the battery by pressing it firmly onto the post.
Tighten the bolt on the negative battery cable until you are unable to move the cable on the battery post.
Close the hood of the Grand Caravan.
