Actuator Supply Voltage A Circuit/Open
Key terms: Control module: a small computer that runs one part of the car · SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions
1What it means in plain English
The engine computer or one of its output circuits has a fault.
2Common causes
- Engine control module fault
- Power or ground connection problem
- Low battery or charging voltage
- Wiring short or open circuit
- Software or memory fault
3Can I drive?
Serious · drive with care
If the engine runs normally, drive carefully to a workshop for diagnosis. If it runs badly, stalls, or will not restart, have the car towed.
This page gives general information. It is not professional advice. For a definite diagnosis and a repair quote, ask a qualified mechanic to inspect the car.
