Hybrid/Electric Vehicle Battery Voltage Shrinkage
Key terms: Control module: a small computer that runs one part of the car · Powertrain: engine, transmission and emissions
1What it means in plain English
The engine or powertrain control system has stored a fault that does not have specific guidance in this database yet.
2Common causes
- Sensor or actuator fault
- Wiring or connector fault
- Vacuum or intake leak
- Fuel or ignition problem
- Control module 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.
