  2. CHECK DRIVING SUPPORT ECU ASSEMBLY (w/ Dynamic Radar Cruise Control System)

    A0021LAE19

    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.
