PINPOINT TEST A: THE COURTESY LAMPS DO NOT ILLUMINATE WITH A DOOR OPEN
A1 CHECK FOR VOLTAGE TO THE AMBIENT LIGHTING MODULE |
-
Use the courtesy lamp switch on the front interior lamp to activate the overhead courtesy lamps.
Do the overhead courtesy lamps illuminate?
|
A2 CHECK THE DOOR AJAR SWITCH OPERATION |
-
Deactivate the overhead courtesy lamps from the front interior lamp.
-
Disconnect: Suspect door latch.
Do the courtesy lamps illuminate?
Yes |
For a front door, INSTALL a new front door latch. REFER to: Front Door Latch (501-14 Handles, Locks, Latches and Entry Systems, Removal and Installation).
For a rear door, INSTALL a new rear door latch. REFER to: Rear Door Latch (501-14 Handles, Locks, Latches and Entry Systems, Removal and Installation).
|
|
A3 CHECK THE DOOR AJAR SWITCH INPUT CIRCUIT FOR A SHORT TO GROUND |
Is the resistance greater than 10,000 ohms?
|
A4 CHECK FOR CORRECT BCM (BODY CONTROL MODULE)
OPERATION |
-
Disconnect and inspect all BCM 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 BCM 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 BCM . REFER to: Body Control Module (BCM) (419-10 Multifunction Electronic Modules, 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. CLEAR the Diagnostic Trouble Codes
(DTCs).

F2 CHECK FOR CORRECT BCM (BODY CONTROL MODULE)
OPERATION |
-
Disconnect and inspect all BCM connectors.
-
Repair:
-
corrosion (install new connector or terminals – clean module pins)
-

-
pushed-out pins – install new pins as necessary
-
Reconnect the BCM 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 BCM . REFER to: Body Control Module (BCM) (419-10 Multifunction Electronic Modules, Removal and Installation).
