Can Communication System (For Lhd) -- Terminals Of Ecu


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

CAN J/C (CAN LH J/C, CAN RH J/C)
HINT:
  1. The connectors connected to the CAN J/C can be distinguished by the colors of the bus lines and the connecting side of the junction connector.
  2. The connectors can be connected to any terminals on the same side.
