Family: Battery Charger Fuse
Code P2E39: Battery Charger B Fuse
Diagnostic & Technical Explanation
Code P2E39 (Battery Charger B Fuse) sets when the control module detects that the fuse protecting the onboard charger's HV feed has opened, cutting power to the charger circuit. The most common physical causes are an overcurrent or short-circuit event inside the charger or its HV feed harness, a fuse that fatigued and opened from age or vibration without an underlying fault, and a corroded connection at the charger-side fuse holder.
