Without Scan Tool

After the problem has been diagnosed and repaired, Diagnostic Trouble Codes may be erased using one of two methods:

WITHOUT A SCAN TOOL
1. Record radio presets.
2. Place ignition switch in OFF position.
3. Disconnect battery ground, for at least 16 seconds.
4. Reconnect the battery ground terminal.
5. Test drive the vehicle and recheck system to see if any codes reappeared.

Note: The Malfunction Indicator (check engine) Lamp (MIL) should be illuminated when the ignition switch is turned to the ON position. When the engine is started, the MIL should go OFF. If the MIL remains ON, a code has been stored in the Electronic Control Module.
