test results.
-
Disconnect: SJB Fuse 13 (5A).
-
Enter the following diagnostic mode on the scan tool: Network Test.
-
Repeat the network test.
-
Do all other modules pass the network test?
Yes
INSTALL the removed fuse. Go To Pinpoint Test F. See: Pinpoint Test F: The Accessory Protocol Interface Module (APIM) Does Not Respond To
The Scan Tool
No
INSTALL the removed fuse. An intermittent fault is not present. Go To Pinpoint Test O. See: Pinpoint Test O: No High Speed Controller Area Network
(HS-CAN) Communication, All Modules Are Not Responding

Normal Operation
The High Speed Controller Area Network (HS-CAN) uses an unshielded twisted pair cable, circuits VDB04 (WH/BU) and VDB05 (WH).
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
ABS module
-
Accessory Protocol Interface Module (APIM) (if equipped)
-
Instrument Cluster (IC)
-
Restraints Control Module (RCM)
-
Occupant Classification System Module (OCSM)
-
PCM
PINPOINT TEST O: NO HS-CAN COMMUNICATION, ALL MODULES ARE NOT RESPONDING
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint
test. See: Initial Inspection and Diagnostic Overview/Communications Network/Inspection and Verification
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
