Clearing Diagnostic Trouble Codes

Stored trouble codes in the computer can be cleared by disconnecting the battery source from the computer. To do this, turn ignition "Off," then remove the battery positive cable or remove the computer fuse for ten seconds. Trouble codes should be cleared after any repairs have been performed. To prevent damage to the computer, the ignition switch must be in the "Off" position when disconnecting or reconnecting power to the computer.

After the computer memory has been cleared, a change may be noted in vehicle performance. To restore normal vehicle performance, drive with engine at normal operating temperature, with the accelerator pedal going through idle, part throttle, and moderate acceleration modes until normal performance is restored.
