Pinpoint Test J: Intermittent No High Speed Controller Area Network (HS-CAN) Communication, Communication Can Be Intermittently
Established
Normal Operation
The High Speed Controller Area Network (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:
-
Wiring, terminals or connectors
PINPOINT TEST J: INTERMITTENT NO HS-CAN COMMUNICATION, COMMUNICATION CAN BE INTERMITTENTLY
ESTABLISHED
NOTE: Various modules will set network DTCs during this test procedure. Clear DTCs from all modules after the diagnostic procedure is completed.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
