1. CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS  .
   1. Turn the ignition switch to OFF.
   2. 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  : Go to  3.

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.

   No  : Repair or replace the short circuit of the harness between the central gateway Control Module and VDC Control Module & H/U.

3. CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS  .
   1. Turn the ignition switch to ON.
   2. Using a tester, measure the voltage between the central gateway Control Module connector and chassis ground.

      Connector & terminal 

      (i366) No. 8 (+) - Chassis ground (-):

      (i366) No. 23 (+) - Chassis ground (-):

   Is the voltage 5 V or less?

   Yes  : CAN communication circuit is normal.

   No  : Go to  4.

4. CHECK CONTROL MODULE  .

   With the tester connected, disconnect control module.

   Connector & terminal 

   (i366) No. 8 (+) - Chassis ground (-):

   (i366) No. 23 (+) - Chassis ground (-):

   Did the voltage change to 5 V or less?

   Yes  : Replace the control module whose voltage has changed.

   No  : Repair or replace the short circuit of the harness between the central gateway Control Module and VDC Control Module & H/U.
