Normal Operation
When the headlamp switch is placed in the parking lamps ON position, voltage is routed through circuit 14 (BN) to the parking lamps. The vehicle security module (VSM) also has an output spliced to circuit 14 (BN) to illuminate the parking lamps.

DTC B2252 - is a continuous and on-demand DTC that sets when the VSM detects a short to voltage from the parking lamps voltage supply circuit.

Possible Causes
- Circuit 14 (BN) short to voltage
- Headlamp switch
- VSM
