B2008 Mercury Code - Wipers On Signal Circuit Short To Ground
Quick Answer
The Smart Junction Box (SJB) sends a voltage signal to the headlamp switch and the light sensor. Common causes include Faulty Wiper Motor, Wiper Motor harness is open or shorted, Wiper Motor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code B2008 Mercury Description
When the headlamp switch is placed in the AUTOLAMPS ON position, the voltage signal is routed to ground. When the SJB detects the headlamp switch in the AUTOLAMPS ON position, the SJB monitors the light sensor input. The light sensor determines the amount of light based on the input received from the ambient lighting conditions. When the ambient level has reached a point (determined by the internal programming of the SJB ), the SJB provides voltage to the headlamps, parking and license plate lamps. The Diagnostic Trouble Code (DTC) sets when the SJB detects a short to ground from the wipers on input circuit.
What are the Possible Causes of the DTC B2008 Mercury?
- Faulty Wiper Motor
- Wiper Motor harness is open or shorted
- Wiper Motor circuit poor electrical connection
- Faulty Headlamp Switch
- Faulty Smart Junction Box (SJB)
