Pinpoint Tests
Pinpoint Test X: Intermittent No High Speed Controller Area Network (HS-CAN) Communication, One Or More Modules Are Not
Responding During Network Test
Normal Operation
The High Speed Controller Area Network (HS-CAN) uses an unshielded twisted pair cable, circuits VDB04 (WH/BU) and VDB05 (WH). In the event
that 1 of the 2 network circuits (HS-CAN + or HS-CAN -) becomes open to a module on the network, unreliable network communication to all modules
on the network may result.
The following modules communicate with the scan tool using the HS-CAN:
-
4X4 control module
-
ABS module
-
Accessory Protocol Interface Module (APIM)
-
Trailer Brake Control (TBC) module
-
Instrument Cluster (IC)
-
Occupant Classification System Module (OCSM)
-
PCM
-
Restraints Control Module (RCM)
-
Transmission Control Module (TCM)
-
Telematics module
This pinpoint test is intended to diagnose the following:
-
Wiring, terminals or connectors
PINPOINT TEST X: INTERMITTENT NO HS-CAN COMMUNICATION, ONE OR MORE MODULES ARE NOT RESPONDING
