The Suzuki version of the Chevy Tracker, the Vitara was sold in the North American market in Latin American countries. Because the vehicle features version two of the on-board diagnostics, which was implemented in 1996 by all vehicle manufacturers, it has a self-learning computer that monitors such things as idle and acceleration cycles.

Step 1

Open the hood on your Vitara. Loosen the black wired negative battery terminal clamp with a metric wrench enough to be able to wiggle the clamp free from the negative battery post.

Step 2

Turn the interior light switch to the "On" position and leave the vehicle for five to 10 minutes. Another way to discharge stored current in the Vitara's computer is to press on the horn while the battery is disconnected. The horn will not sound off since the battery is not connected, but it will drive the stored energy from the capacitor, as will turning on the headlight switch.

Step 3

Reconnect the negative battery terminal clamp and tighten it with the metric wrench. Start the engine of the Vitara and test drive it, preferably on low-traffic roads since there will be some performance problems until the computer completes the relearn of its adaptive strategy.
