    What does this fault code mean?

    The code is event-based and is used as information. It therefore does not mean that the control module where it is active has a fault. The ECM checks the battery voltage, and the code is set when the conditions for the test are met.

    Possible causes

    • Damaged charging system

    What you can do

    1. 1Check that the fuses are intact
    2. 2If you suspect the charging system is damaged, have a workshop check it
    3. 3If you have diagnostic equipment: read the battery voltage in live data with the engine running and see whether it changes when high-consumption functions are switched on
    4. 4Clear the code and road test the car to see whether it returns

    Symptoms you may notice3

    • The engine does not start and the starter motor cranks
    • The engine stalls while driving, hard to tell when it happens
    • The engine does not start, hard to tell when it happens

    General guidance for car owners. Diagnosis on the car can point to a different cause.
