Battery Energy Control Module (BECM)
Volvo models this fault code applies to
Applies to the following models:
1 modelV60 (2011–)
Show models by year and engine (2)
What does this fault code mean?
The control module communicates on HS-CAN using a configuration ID that must match the one sent out by the central electronic module (CEM). The code is set when the ID does not match, which happens if a used control module with other software has been fitted.
Possible causes
- Incorrect configuration ID, for example a used control module not intended for this car
- Sporadic breaks on one of the CAN wires in the network
What you can do
- 1Read and note the fault code, clear it and road test to check whether it returns
- 2Have a workshop check the configuration ID and load the correct software into the control module
- 3The high voltage system should only be handled by qualified personnel, so have a workshop carry out all work on the battery and other high voltage parts
Symptoms you may notice3
- Red warning symbol and message in the display
- Drive modes PURE, SAVE and AWD disengage automatically or cannot be selected
- The combustion engine runs more often than normal in HYBRID mode
What the fault can affect2
- The control module stops sending messages on HS-CAN
- Electric propulsion is not possible
