Check Can Communication Line For Open
- Ignition "OFF"
- Disconnect ECM harness connector
- Measure resistance between terminals 77 and 78 of the ECM harness connector.
- Is resistance within the specification?
YES
- Go to next step as below
NO
- Check for open in wiring related to the CAN communication (ECM, EPS, MTS and vertical resistor at the junction box). Repair as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure
NOTE: Vertical Resistor Resistance: Approx. 110-1300.
