CautionSeverity: Caution - get it checked when you can
System Voltage Unstable
Key terms: SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions
1What it means in plain English
This range covers vehicle speed, idle and oil-pressure control, charging-system voltage, and brake-switch circuits.
2Common causes
- Carbon build-up in the throttle body
- Faulty idle air control valve
- Faulty vehicle speed sensor
- Faulty charging system or weak battery
- Wiring or connector fault
3Can I drive?
The electrical system may fail and the battery may go flat, risking a stall. If the battery or charging warning light is on, drive straight to a workshop.
