Normal Operation
Under normal operation, when a RH or LH turn is selected, the smart junction box (SJB) sends voltage to the front turn lamps through (LH) circuit 1342 (GY/BK) or (RH) circuit 1341 (DB/OG). The turn lamps are grounded through circuit 1205 (BK).

Possible Causes
- An open in circuit 1205 (BK), 1341 (DB/OG) or 1342 (GY/BK)
- A short to ground in circuit 1341 (DB/OG) or 1342 (GY/BK)
