CAN COMMUNICATION SYSTEM > Check CAN Bus Line for Short to GND (w/ Stop and Start System)

for Preparation Click here


DESCRIPTION

There may be a short circuit between the CAN bus line and GND when there is resistance between terminals 6 (CANH) and 4 (CG) or terminals 14 (CANL) and 4 (CG) of the DLC3.

Symptom

  4. Steering column assembly (Power steering ECU)
  5. Brake actuator assembly (Skid control ECU)
  6. Spiral cable sub-assembly (Steering sensor)
  7. Yaw rate sensor
  8. Center airbag sensor assembly
  9. Air conditioning amplifier assembly
  10. Certification ECU*1
  11. Main body ECU

INSPECTION PROCEDURE

NOTICE:
  1. Turn the ignition switch off before measuring the resistances of the CAN main wire and the CAN branch wire.
  2. After the ignition switch is turned off, check that the key reminder warning system and light reminder warning system are not in operation.
  3. 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.

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

1.CHECK FOR SHORT TO GND IN CAN BUS WIRE (DLC3 BRANCH WIRE)

  1. Turn the ignition switch off.
