  2. PRECAUTIONS FOR TROUBLESHOOTING


    1. If the malfunction is due to connectors being loosely connected, or improper installation of parts, reconnecting the connectors or removing and reinstalling the parts may temporarily or completely correct the problem.

    2. To determine the malfunctioning area, use DTCs, freeze frame data and other data to help determine conditions at the time of the malfunction. Write down the data before disconnecting connectors or removing and installing parts.

    2. After removal and installation of parts has been performed, check for DTCs and confirm that none are output.
