  1. CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS  .
    1. Turn the ignition switch to OFF.
    2. Disconnect the central gateway control module connector.
    3. Using a tester, measure the resistance between the central gateway control module connector and chassis ground.

      Connector & terminal 

      (i366) No. 8 - Chassis ground:

      (i366) No. 23 - Chassis ground:

    Is the resistance less than 10 Ω?

    Yes:  Go to  2.

    No:  Currently, it is normal.

  2. CHECK CONTROL MODULE  .

    With the tester connected, disconnect control module.

    Connector & terminal 

    (i366) No. 8 - Chassis ground:

    (i366) No. 23 - Chassis ground:

    Did the resistance change to 10 Ω or more?

    Yes:  Replace the control module whose resistance has changed.
