What does this fault code mean?

Although the code is named battery monitor module, it concerns the 12-volt supply to the engine control module (ECM). The supply is checked at ignition switch-on, and the code is set if the supply voltage is missing.

Possible causes

Damaged fuse for the voltage supply
Open circuit in the voltage wire

What you can do

1Check that the fuse for the voltage supply to the engine control module is intact
2Check the battery terminals and connections for contact resistance and oxidation
3Use a multimeter to check that the voltage wire to the engine control module has voltage when the ignition is on
4Check the wire running from the ECM to the battery for breaks, contact resistance and oxidation
5Clear the code and road test the car to see whether it returns
6If the fault remains, have a workshop check the wiring and the supply to the engine control module

Symptoms you may notice3

The check engine lamp lights or behaves abnormally
The battery shows low voltage
