Locks, Latches and Entry Systems — 2016 workshop reference 1416

V3 CHECK THE LIN (LOCAL INTERCONNECT NETWORK) CIRCUIT FOR A SHORT TO GROUND

Connect BCM C2280B. Ignition OFF. Disconnect BCM C2280B. Measure:

Click to display connectors

Positive Lead	Measurement / Action	Negative Lead
C4458-2		Ground

Is the resistance greater than 10,000 ohms?

Yes	GO to V4
No	REPAIR the circuit.

V4 CHECK THE LIN (LOCAL INTERCONNECT NETWORK) CIRCUIT FOR AN OPEN

Measure:

Click to display connectors

Positive Lead	Measurement / Action	Negative Lead
C4458-2		C2280B-26

Is the resistance less than 3 ohms?

Yes	GO to V5
No	REPAIR the circuit.

V5 CHECK FOR CORRECT RTM (RADIO TRANSCEIVER MODULE) OPERATION

Disconnect and inspect the RTM connector. Repair:

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

Reconnect the RTM connector and make sure it seats and latches 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 RTM. REFER to: Radio Transceiver Module (RTM) (419-10 Multifunction Electronic Modules, Removal and Installation). TEST the system for normal operation. If the concern is still present, GO to V6
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.

V6 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

Disconnect and inspect all the BCM connectors. Repair:

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

Reconnect the BCM connectors and make sure they seat and latch correctly. Operate the system and determine if the concern is still present.
