Principles of Operation
The autolamp system provides light-sensitive automatic on-off control of the exterior lamps normally controlled by the regular headlamp switch. The autolamp system keeps the lamps on for a preselected period of time (20 seconds) after the ignition switch is turned off. The preselected time lapse is not adjustable.
Inspection and Verification
Verify the customer concern by operating the autolamps.
Visually inspect for the following obvious signs of mechanical and electrical damage.
Visual Inspection Chart Mechanical Electrical
Headlamp switch
Central junction box (CJB) Fuse:
29 (5A)
BJB Fuse 3 (30A)
Wiring harness
Loose or corroded connections
Headlamp bulb

DRL jumper (if equipped)
RAP module (if equipped)
Light sensor amplifier
Correct mounting of light sensor amplifier
