Charging system

The exact symbol can vary between makes and models. Also check the message displayed by the vehicle.

How urgent is it?

Stop somewhere safe and arrange checks; the engine may stop as the battery runs down.

How to recognise it

Battery with plus and minus signs.

What it can mean

With the engine running, it indicates a charging problem, not necessarily a battery that needs replacement.

What to do

Switch off non-essential electrical loads and find a safe place. Arrange prompt checks; stop the engine for overheating or other serious warnings.

Before clearing the light or codes

Photograph the dashboard message and save all codes, the reporting module, fault status and freeze-frame data. Clearing can remove useful evidence without repairing the cause.

From warning light to inspection

A warning light can have many causes. The example codes below have NOT been scanned from your vehicle.
