NOTE: When the CAN communication circuit is measured, combined resistance of end resistance (120 Ω) in ECM and end resistance (120 Ω) in 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. Disconnect the connectors of the ECM and central gateway Control Module.
2. Using a tester, measure the resistance between control module terminals.

  (B134) No. 3 - (B134) No. 14:
  
  (i366) No. 22 - (i366) No. 7:
Is the resistance 114 - 126 Ω?

Yes : Go to 2.

No : Replace the control module whose value is out of the specification.
CHECK HARNESS (MAIN-CAN) .
1. Disconnect the steering sensor connector.
2. Using a tester, measure the resistance between steering sensor connector and ECM connector, and between steering sensor connector and central gateway Control Module connector.

  (i74) No. 2 - (B134) No. 14:
  
  (i74) No. 3 - (i366) No. 22:
  
  (i74) No. 2 - (i366) No. 7:
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.
