Normal Operation
Under normal operation, ground for the ajar switches is provided through circuit 1205 (BK). When any door is ajar, ground to the smart junction box (SJB) is interrupted. The SJB provides voltage to the lamps through circuit 53 (BK/LB). When the dimmer control is rotated to the interior lamp detent position, ground is provided to the smart junction box (SJB) through circuit 2085 (VT/YE). When any door is closed, ground is provided to the SJB through the circuits.
- Driver door ajar switch, circuit 1312 (LG/BK).
- Passenger door ajar switch, circuit 1314 (YE/LG).

Possible Causes
- An open in circuit 1205 (BK), 1312 (LG/BK) or 1314 (YE/LG)
- A short to ground in circuit 2085 (VT/YE) or 54 (LG/YE)
- A short to voltage in circuit 53 (BK/LB), 1312 (LG/BK) or 1314 (YE/LG)
- Door ajar switch
- Dimmer control switch
- Smart junction box (SJB)
