CAN COMMUNICATION SYSTEM TERMINALS OF ECU

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 remainder warning system are not operating.

  • 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 the connectors, open the doors and leave them open.

Tech Tips

Operating the ignition switch, any other switches, or a door triggers related ECU and sensor communication on the CAN.

This communication will cause the resistance value to change.

Note

This section describes the standard CAN values for all CAN related components.
