pushed-out pins - install new pins as necessary

Reconnect the VDM connectors and related in-line connectors. Make sure they seat and latch correctly. Operate the system and determine if the concern is still present.

Is the concern still present?

Yes		CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new VDM. REFER to: Vehicle Dynamics Control Module (VDM) (204-05 Vehicle Dynamic Suspension, Removal and Installation).
No		The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.

No High Speed Controller Area Network 3 (HS-CAN3) Communication, All Modules Are Not Responding

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

Normal Operation and Fault Conditions

Diagnostic messages sent/received between the diagnostic scan tool and the HS-CAN3 modules are accessed through the HS-CAN2 circuits on the DLC. REFER to: Communications Network (418-00 Module Communications Network) .

Possible Sources

Fuse Wiring, terminals or conectors ACM APIM (if equipped) DSP (if equipped) FCDIM (if equipped) IPC GWM

PINPOINT TEST AF : NO HIGH SPEED CONTROLLER AREA NETWORK 3 (HS-CAN3)

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.

AF1 CHECK THE DLC (DATA LINK CONNECTOR) PINS FOR DAMAGE

Igntion 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 AF2
No		REPAIR the DLC as necessary.

AF2 CHECK FOR HS-CAN2 (HIGH SPEED-CONTROLLER AREA NETWORK 2) COMMUNICATION

Using a diagnostic scan tool, perform a network test.

Does the RCM pass the network test?
