NOTE: When CAN communication circuit is measured, combined resistance of end resistance (120 Ω) in ECM and end resistance (120 Ω) in Body Control Module can be measured. The combined resistance is more than 56 Ω and less than 64 Ω. When the measured resistance value is 64 Ω or more, either of end resistance or main wiring harness may have malfunction such as open circuit.

CHECK CONTROL MODULE .
1. Disconnect the ECM and Body Control Module connectors.
2. Using a tester, measure the resistance between control module terminals.

  (B134) No. 4 - (B134) No. 15:
  
  (HV42) No. 2 - (HV42) No. 3:
Is the resistance 114 - 126 Ω?

Yes : Go to 2.

No : Replace the control module whose value is out of the specification.
CHECK HARNESS .
Using a tester, measure the resistance between ECM connector and Body Control Module connector.

(B134) No. 4 - (HV42) No. 2:

(B134) No. 15 - (HV42) No. 3:

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.
