Open in CAN Main Bus Line

Open in CAN Main Bus Line

DESCRIPTION




There may be an open circuit in the CAN main bus wire and/or the DLC3 branch wire when the resistance between terminals 6 (CANH) and 14 (CANL) of the DLC3 is 69 ohms or higher.

INSPECTION PROCEDURE

NOTE:
- Turn the ignition switch off before measuring the resistances of CAN bus main wires and CAN bus branch wires.
- 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 any 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. .This communication will cause the resistance value to change.
