With Generic Scan Tool

HOW TO ERASE DIAGNOSTIC TROUBLE CODES (WITH GENERIC SCAN TOOL)
Diagnostic Trouble Codes (DTC) can be erased by the following method.

1. If the ignition switch stays "ON" after repair work, be sure to turn ignition switch "OFF" once. Wait at least 5 seconds and then turn it "ON" (engine stopped) again.
2. Clear A/T related DTCs by initiating the transmission self diagnostic procedure used without scan tools.

A/T Self Diagnostic Procedure (part 1):

A/T Self Diagnostic Procedure (part 2):

A/T SELF-DIAGNOSTIC PROCEDURE (Without Consult)". (The engine warm-up step can be skipped when performing the diagnosis only to erase the DTC.)
3. Select Mode 4 with Generic Scan Tool (GST) to clear remaining emissions and engine control related DTCs.

NOTES:
- If the diagnostic trouble code is not for A/T related items, skip step 2.
- If the battery terminal is disconnected, the diagnostic trouble code will be lost within 24 hours.
- Mode 4 on the GST may only clear engine control/emission related DTCs. Transmision control related DTCs may have to be cleared by manually initiating the transmission self diagnostic procedure. If the transmission fault is no longer present or has been repaired, the DTC for that fault will be erased while the transmission self-diagnostic sequence is running.
