Bus "B" (Smart System Can): Notes

NOTE:
  • When measuring the resistance of CAN communication circuit, measure it in sleep status. To enter sleep status
    • With ignition switch OFF and key or switch operation stopped, keep the doors, trunk, and rear gate all closed for one minute or more.
    • On models with keyless access function, keep the access key 2 m or more away from the vehicle.
  • When the bus line is measured, combined resistance of the end resistance (120 O) in body integrated unit and the end resistance (120 O) in keyless access CM can be measured. The combined resistance is supposed to be approximately 57 - 63 O. If the measured resistance value becomes 56 O or less, main wiring harness or related lines may be shorted. Or, the combined resistance may have changed because of a resistance other than the end resistance created on the circuit. If the measured value is 64 O or more, there may be a malfunction such as open circuit in one of the end resistances or in the main wiring harness.

    Also, even when the resistance value falls within approx. 57 - 63 O, related lines may be open if an error of communication for initializing or a CAN system U-code has occurred. (The resistance won't be between approx. 57 - 63 O if the main wiring harness is open.)
