Can I drive with 12-volt system problem?
Driving risk with 12-volt system problem depends on the warning state, loss of control or performance, heat, smoke, leakage, and whether the condition is worsening. Use the stop conditions below before moving the vehicle.
Plausible causes
- Electrified-vehicle charging, low-voltage, thermal, or propulsion concern
- 12-volt supply or wake-up path
- EVSE, port, charge-control, thermal, or high-voltage path
Useful next checks
- Capture the exact READY state, warning and charger LEDs, AC/DC source, SOC, temperature, schedule, and visible port condition. Never touch orange cables or a service disconnect.
- After crash, flood, underbody/pack impact, exposed orange cable, pack leak, smoke/flame, increasing heat, hissing/popping, or chemical odor: exit, move away and upwind, call emergency services, and do not touch, charge, or store indoors.
- Stabilize/test 12-volt supply and complete full-module scan
