Terminals Of Ecu

NOTE:
  • Turn the ignition switch off before measuring the resistances of the CAN bus main wire and the 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 the connectors, open the doors and leave them open.

HINT:

Operating the ignition switch, any other switches or 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.
