Flow of Diagnosis


Foreword

Before Proceeding With The Following Troubleshooting:

- Vehicle speed and engine speed detected by the PCM may differ from that indicated by the speedometer and the tachometer. Check the vehicle speed and engine speed during driving mode by using the SST (NGS Tester).
- If the OBD II system check is not completed while the drive mode procedure is carried out, the following cause is guessed.
1. The OBD II system detects the malfunction.
