  3. CHECK DRIVING SUPPORT ECU ASSEMBLY (w/ Dynamic Rader Cruise Control System)

    B002L2JN23

    1. Disconnect the I19 driving support ECU assembly connector.

      Note

      Do not apply excessive force to the connector. If a force of 10 kg or more is applied, the connector may be broken.

    2. Measure the resistance and voltage on the wire harness side connector according to the value(s) in the table below.
