Pinpoint Test S: No High Speed Controller Area Network (HS-CAN) Communication, All Modules Are Not Responding
Refer to Wiring Diagram Set 14, Module Communications Network for schematic and connector information. See: Diagrams/Electrical
Diagrams/Diagrams By Number
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:
-
Wiring, terminals or connectors
-
4X4 control module (if equipped)
-
ABS module
-
Accessory Protocol Interface Module (APIM) (if equipped)
-
Instrument Cluster (IC)
-
Occupant Classification System Module (OCSM)
-
PCM
-
Restraints Control Module (RCM)
-
Transmission Control Module (TCM) (if equipped)
PINPOINT TEST S: 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.

S1 CHECK THE DLC PINS FOR DAMAGE
-
Ignition OFF.
-
Disconnect the scan tool cable from the Data Link Connector (DLC).
-
Inspect DLC pins 6 and 14 for damage.
-
Are DLC pins 6 and 14 OK?
Yes
GO to S2.
No
REPAIR the DLC as necessary. CLEAR the DTCs. REPEAT the network test with the scan tool.
