Park/Side Marker and Tail Lamps

The park/side marker and tail lamps are split between the following 4 fuses:
- The FR PRK
- The LR PRK
- The RR PRK
- The TRL PRK

These fuses receive voltage from the park lamp relay. When the headlamp and panel dimmer switch is in the auto position, the body control module (BCM) controls the relay by grounding CKT 1080 based on the input of the ambient light sensor. The park LPS fuse supplies battery positive voltage (B+) to the relay at all times.

When the headlamp and panel dimmer switch is in the PARK position, the relay is by passed through the INT PRK fuse. Current flows from the PARK LPS fuse through the headlamp and panel dimmer switch to the INT PRK fuse in order to feed the following fuses:
- The FR PRK
- The LR PRK
- The RR PRK
- The TRL PRK
