The Suzuki check engine light will come on when you reach certain mileage milestones, if the light switch is defective or there is a serious problem with your engine. Mileage rollovers that trip the check engine light include 50,000 miles, 80,000 miles and 100,000 miles. If you think that your Suzuki's check engine light has come on unnecessarily, then you can quickly and easily reset the check engine light by briefly disconnecting the car battery. If the engine light comes back on after the battery has been disconnected, then you may have a problem requiring professional repair.

Step 1

Remove all metal jewelry that may accidentally come into contact with the battery, such as rings, bracelets and necklaces. Put on safety goggles and gloves.

Step 2

Locate the ground, or negative, clamp on the battery. The negative ground will be marked with a "-" sign and connected to a black cable.

Step 3

Loosen the nut that holds the negative clamp in place.

Step 4

Remove the clamp from the negative post.

Step 5

Wait 20 to 30 seconds.

Step 6

Reattach the clamp to the negative post.

Step 7

Tighten the nut that holds the negative clamp in place.

Step 8

Turn on your Suzuki. If the check engine light comes back on, you may have a problem with either the engine or the check engine light itself. Bring your car to an auto mechanic for maintenance.
