Communications Network — 2016 workshop reference 5937

Refer to Wiring Diagrams Cell 14 for schematic and connector information.

Normal Operation and Fault Conditions

The HS-CAN2 modules communicate with the diagnostic scan tool directly through the DLC circuits. REFER to: Communications Network (418-00 Module Communications Network) .

Possible Sources

Fuse Wiring, terminals or connectors ABS module CCM (if equipped) GWM HUD module (if equipped) OCSM PSCM SCCM RCM VDM

PINPOINT TEST AE : NO HIGH SPEED CONTROLLER AREA NETWORK 2 (HS-CAN2)

COMMUNICATION, ALL MODULES ARE NOT RESPONDING

NOTE: Various modules set network DTCs during this test procedure. Clear DTCs from all modules after completing the diagnostic procedure.

AE1 CHECK THE DLC (DATA LINK CONNECTOR) PINS FOR DAMAGE

Ignition OFF. Disconnect the diagnostic scan tool cable from the DLC. Inspect the DLC pins 3 and 11 for damage.

Are DLC pins 3 and 11 OK?

Yes	GO to AE2
No	REPAIR the DLC as necessary.

AE2 CHECK THE HS-CAN2 (HIGH SPEED-CONTROLLER AREA NETWORK 2) TERMINATION RESISTANCE

Disconnect negative battery cable. Measure:

Click to display connectors

Positive Lead	Measurement / Action	Negative Lead
C251-3		C251-11

Is the resistance between 54 and 66 ohms?

Yes	GO to AE3
No	GO to AE5

AE3 CHECK THE HS-CAN2 (HIGH SPEED-CONTROLLER AREA NETWORK 2) (+) AND HS-CAN2 (HIGH SPEED-CONTROLLER AREA NETWORK 2) (-) CIRCUITS FOR A SHORT TO GROUND
