Without Scan Tools

HOW TO ERASE DTC (No Tools)
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. Perform "TCM SELF-DIAGNOSTIC PROCEDURE (No Tools)".
3. Change the diagnostic test mode from Mode II to Mode I by turning the mode selector on the ECM.
