Terminals Of Ecu

WARNING: This page is about a different variant/trim than selected.
NOTE:
  • Turn the power switch off before measuring the resistances between CAN main bus wires and between CAN main bus branch wires.
  • Turn the power switch off before inspecting CAN bus wires for a ground short.
  • After the power switch is turned off, check that the key reminder warning system and light reminder warning system are not operating.
  • Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the power 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.
  • This information describes the standard CAN values for all CAN related components.
