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.

CHECK CONTROL MODULE .
1. Turn the ignition switch to OFF.
2. Disconnect the central gateway control module connector.
3. Using a tester, measure the resistance between control module terminals.

  (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 central gateway control module. Ref. to BODY CONTROL/COMMUNICATION SYSTEM>CENTRAL gateway control module
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.

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.
