The HS-CAN is used for communication between the PCM, the ABS module and the instrument cluster (IC). An open circuit VDB04 (WH/BU)
(HS-CAN +) or VDB05 (WH) (HS-CAN -) may cause intermittent or unreliable communication to all modules on the HS-CAN.
In the event that either circuit VDB04 (WH/BU) (HS-CAN +) or VDB05 (WH) (HS-CAN -) becomes open to any module on the network, unreliable
network communication to all modules on the network may result.
This pinpoint test is intended to diagnose the following:
