Test T: Door Ajar Warning Never/Always On

Turn ignition on. Wait until prove-out cycle is completed. If door ajar warning indicator is always on, go to next step. If door ajar warning indicator is never on, turn ignition off. Remove indicator bulb. Check for continuity between indicator bulb terminals. If continuity is not present, replace bulb. If continuity is present, go to next step.
With ignition off, open and close each door individually while observing courtest lights. If courtesy lights do not come on, repair as necessary before continuing. If courtesy lights comes on, go to next step.
Close all doors. Leave ignition off. Remove instrument cluster. See REMOVAL & INSTALLATION . With instrument cluster connector C274 connected, measure voltage between ground and instrument cluster connector C274, pin No. 11 (Brown/White wire). See Figure . Open door and measure voltage again. If voltage is greater than 10 volts with all doors closed and less than one volt with any door open, replace instrument cluster. If voltage is not as specified, go to next step.
Turn ignition off. Disconnect instrument cluster connector C274. Disconnect diode junction box 2 connector C2010. See Figure and Figure . Measure resistance of Brown/White wire between instrument cluster connector C274, pin No. 11 and diode junction box 2 connector C2010, pin No. 19. Measure resistance of Brown/White wire between ground and instrument cluster connector C274, pin No. 11. If resistance between instrument cluster connector and diode junction box 2 connector is less than 5 ohms, and greater than 10,000 ohms between instrument cluster connector and ground, go to next step. If resistances are not as specified, repair open or short in Brown/White wire.
Turn ignition off. Disconnect 12-pin timer module connector located behind left side of instrument panel. Measure resistance of Brown/White wire between diode junction box 2 connector C2010, pin No. 20 and 12-pin timer module connector. Measure resistance of Brown/White wire between ground and 12-pin timer module connector. If resistance between diode junction box 2 connector C2010, pin No. 20 and 12-pin timer module connector is less than 5 ohms, and greater than 10,000 ohms between 12-pin timer module connector and ground, replace Green diode strip. If resistances are not as specified, repair open or short in Brown/White wire.
