Normal Operation
When the smart junction box (SJB) detects a request for the LH or RH turn signal, the SJB provides voltage, through the bussed electrical center (BEC), to the front turn lamps through circuit 1342 (GY/BK) (LH front turn lamp) or circuit 1341 (DB/OG) (RH front turn lamp). The turn lamps are grounded through circuit 1205 (BK) through the BEC.

Possible Causes
- Circuit 1341 (DB/OG) open, short to ground or voltage
- Circuit 1342 (GY/BK) open, short to ground or voltage
- Circuit 1205 (BK) open
- BEC
- SJB
