PINPOINT TEST O : One Or More Demand Lamps Are Inoperative

O1 CHECK THE COURTESY LAMP OPERATION

Open the left front door and observe the interior courtesy lamps.

Do the interior courtesy lamps illuminate?

Yes	GO to O2.
No	GO to Pinpoint Test F .

O2 CHECK ALL THE DEMAND LAMPS

Check the operation of all the demand (map and vanity mirror) lamps.

Are all the demand lamps inoperative?

Yes	VERIFY the BCM fuse 4 (10A) is OK. If OK, GO to O3.
No	For a vanity mirror or glove compartment lamp, GO to O4. For a map/reading lamp, GO to O6. For a task lamp (police package only), GO to O8.

NOTE: If the jumper wire fails, refer to the OEM ELECTRICAL WIRING DIAGRAM INTRODUCTION to identify the possible causes of the circuit short.

O3 BYPASS THE BCM

Disconnect: BCM C2280D.

O10 CHECK FOR CORRECT BCM OPERATION

Disconnect the BCM connectors.

Repair:
- corrosion (install new connector or terminals - clean module pins)
- corrosion (install new connector or terminals - clean module 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.

Is the concern still present?

Yes	CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, discontinue this test and follow TSB instructions. If no TSBs address this concern, INSTALL a new BCM. REFER to Multifunction Electronic Modules - Without Intelligent Access or REFER to Multifunction Electronic Modules - With Intelligent Access .
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. CLEAR the DTCs.
