O5 CHECK THE MS-CAN (MEDIUM SPEED-CONTROLLER AREA NETWORK) CIRCUITS BETWEEN THE APIM (SYNC MODULE) AND THE GWM (GATEWAY MODULE A) FOR AN OPEN

Measure:

Click to display connectors

Positive Lead	Measurement / Action	Negative Lead
C2342-16		C2431-23
C2342-17		C2431-22

Are the resistances less than 3 ohms?

Yes	GO to O6
No	REPAIR the circuit in question.

O6 CHECK FOR CORRECT APIM (SYNC MODULE) OPERATION

Ignition OFF. Disconnect and inspect the APIM connector and related in-line connectors. Repair:

corrosion (install new connector or terminals - clean module pins) damaged or bent pins - install new terminals/pins pushed-out pins - install new pins as necessary

Reconnect the APIM connector 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, Click here to access Guided Routine (APIM).
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.
