# INFO. HEADLAMPS/PARKING LAMPS REMAIN ON

#### SUBJECT: INFORMATION - HEADLAMPS/PARKLAMPS REMAIN ON WHEN THE TWILIGHT SENTINAL (T82) OR DAYTIME RUNNING LAMPS (T61) ARE ENABLED, THE IGNITION SWITCH IS TURNED OFF AND THE VEHICLE IS NOT IN PARK

#### MODELS: 1995 BUICK LESABRE, PARK AVENUE 1995 OLDSMOBILE EIGHTY EIGHT, NINETY EIGHT 1995 PONTIAC BONNEVILLE

SOME OWNERS MAY COMMENT THAT THE HEADLAMPS/PARKLAMPS DO NOT GO OUT WHEN THE TWILIGHT SENTINEL IS ENABLED AND THE IGNITION SWITCH IS TURNED "OFF" BEFORE PLACING VEHICLE IN "PARK". THIS IS A NORMAL FUNCTION OF THE LAMP CONTROL MODULE AND DOES NOT REPRESENT A FAILURE WITH THE MODULE.

TO VERIFY THAT THE LAMP CONTROL MODULE IS OPERATING PROPERLY, PERFORM THE FOLLOWING STEPS:

1. ENGAGE PARKING BRAKE.

2. TURN IGNITION SWITCH TO "RUN".

3. ACTIVATE THE TWILIGHT SENTINEL.

4. COVER PHOTOCELL.

5. VERIFY THAT THE HEADLAMPS/PARKLAMPS ARE ON.

6. WITH THE ENGINE RUNNING, PLACE GEAR SELECTOR OUT OF "PARK".

7. TURN IGNITION SWITCH TO "OFF" (THE HEADLAMPS/PARKLAMPS SHOULD STILL BE ON).

8. PLACE VEHICLE IN "PARK".

9. TURN OFF THE TWILIGHT SENTINEL.

THE HEADLAMPS/PARKLAMPS SHOULD GO OUT. IF THE HEADLAMPS/PARKLAMPS REMAIN ON, REFER TO THE FOLLOWING BULLETINS:

OLDSMOBILE AND PONTIAC: SAFETY RECALL BULLETIN - CAMPAIGN #95-C-04 (GM OF CANADA CAMPAIGN #4D48)
