CAN COMMUNICATION SYSTEM Check CAN Bus Lines for Short Circuit (w/ Stop and Start System)

DESCRIPTION

There may a short circuit in the CAN main wire and/or CAN branch wire when the resistance between terminals 6 (CANH) and 14 (CANL) of the DLC3 is below 54 Ω.

Symptom Trouble Area

  • Short in CAN bus wire

  • ECM

  • Combination meter assembly (Combination meter ECU)

  • Steering column assembly (Power steering ECU)

  • Brake actuator assembly (Skid control ECU)

  • Spiral cable sub-assembly (Steering sensor)

  • Yaw rate sensor

  • Center airbag sensor assembly

  • Air conditioning amplifier assembly

  • Certification ECU*1

  • Main body ECU

  • Power management control ECU*1

  • CAN No. 1 junction connector

  • CAN No. 2 junction connector

INSPECTION PROCEDURE

Note


  • Turn the ignition switch off before measuring the resistances of the CAN main wire and the CAN branch wire.

  • After the ignition switch is turned off, check that the key reminder warning system and light reminder warning system are not in operation.

  • Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the ignition switch, any other switches or the doors. If doors need to be opened in order to check connectors, open the doors and leave them open.

Tech Tips

Operating the ignition switch, any switches or any doors triggers related ECU and sensor communication with the CAN, which causes resistance variation.
