Normal Operation
The smart junction box (SJB) provides voltage to the puddle lamps through circuit CLN25 (VT). The puddle lamps have separate ground circuits. The LH exterior mirror is grounded through circuit GD133 (BK), and the RH exterior mirror is grounded through circuit GD140 (BK/GN).

DTC B2A39 - sets when the SJB detects an open on the puddle lamp output circuit.

DTC B2A3A - sets when the SJB detects a short to ground on the puddle lamp output circuit.

Possible Causes
- Fuse
- Circuitry
- Exterior mirror
- SJB
