Diagnose
ISO11898
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.
Before to check on one of the wire, be sure you know the CANbus layout of the vehicle. Depending on the ECUs mounted, you could find splitters and extension cables to link all the network together.
In practice, always start to check the CANbus from one end to main ECU (EB+ or U-ABS), then check again the different cable or splitters separately.
