Normal Operation
Under normal operation, when park lamps are selected, the headlamp switch sends a ground signal to the smart junction box (SJB) through circuit 1401 (BK/LG). The SJB then sends voltage to the front parking and side marker lamps through circuit 1057 (OG/BK). The SJB sends voltage to the rear parking and license lamps through circuit 1058 (BN/WH). The lamps are grounded through circuit 1205 (BK).

Under normal operation, when park lamps are selected the headlamp switch sends a ground signal to the smart junction box (SJB) through circuit 1401 (BK/LG).

Possible Causes
- A short to ground in circuit 1401 (BK/LG)
- A short to voltage in circuit 1057 (OG/BK) or 1058 (BN/WH)
- Lamp
- Smart junction box (SJB)
