Diagnostic
ISO11898 - DIN plug only !
The Haldex Can Bus uses 4 wires, 2 are for power supply, 2 for the communication (CAN High and CAN Low)
It can be used for ECU extensions, diagnostic or telematic.
The main use with 3rd party devices, is communication purpose. Only communication wires and B- may be used in this case : you can check if ECU CAN High/Low average voltage is Ok, and also B- on the DIN connector.
Some other devices may only use B+/B- on this connector.
