Code result
P25FF
Electrical System Voltage Stabilizer Control Module Performance
Moderate severity
What it means
The voltage stabiliser module (DC/DC converter for stop-start engine cranking events) does not maintain the regulated 12 V output during high transient loads. Sensitive electronics may reset during cranking.
Is it safe to drive?
Use caution
The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
