Terminals Of Ecu

WARNING: This page is about a different car, the 2005 Toyota 4Runner. However, it is still accessible from the selected car via links, so may be relevant.

HINT:

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

CAN J/C

CAN J/C connectors.

HINT:

The connectors connected to the CAN J/C can be distinguished by the colors of the bus lines and the connecting side of the connector.
J48, J49, J50 and J51 are interchangeable.
