NOTE: When the CAN communication circuit is measured, combined resistance of end resistances (120 Ω) within the central gateway control module can be measured. The combined resistance is more than 52 Ω and less than 62 Ω with the stabilizing circuit included. When the measured resistance value is 62 Ω or more, either one of the end resistances, or stabilizing circuit, or main wiring harness may have malfunction such as open circuit.
  1. CHECK CONTROL MODULE  .
    1. Disconnect the central gateway control module connector.
    2. Using a tester, measure the resistance between control module terminals.

      Connector and terminal 

      (i88) No. 12 - (i88) No. 13:

      (i88) No. 35 - (i88) No. 36:

      Is the resistance 114 - 126 Ω?

      Yes  : Go to  2 .

      No  : Replace the control module whose value is out of the specification.

  2. CHECK HARNESS (OPEN CIRCUIT)  .
    1. Disconnect the cockpit control module connector.
    2. Using a tester, measure the resistance between cockpit control module connector and central gateway control module connector.

      Connector and terminal 

      (i101) No. 30 - (i88) No. 12:

      (i101) No. 31 - (i88) No. 13:

      (i101) No. 30 - (i88) No. 36:

      (i101) No. 31 - (i88) No. 35:

      Is the resistance less than 10 Ω?

      Yes  : It is possible that temporary poor communication occurs.

      No  : Repair or replace the open circuit of harness.
