  2. CHECK DRIVING SUPPORT ECU ASSEMBLY

    A01G7VEE15

    Note


    • As disconnecting the connector to perform inspections may cause DTCs to be stored, clear DTCs after performing inspections.

    • As the connector may be damaged if a load of more than 10 kg (22 lb) is applied to it, do not apply any more load than necessary to the connector.
