Checking control module version

Caution! It is essential that control module software in the car correspond. The control module version depends on the software version that is programmed. If the version or control module do not correspond with the car specification, one or more control modules can register this fault. It is therefore important to check all control modules.

A permanent diagnostic trouble code (DTC) indicates that the car has been previously repaired using incorrect components or software. Find out if the car has been repaired. If so, has a component has been replaced or software downloaded.
Go into VIDA communication and read off all control module and software P/Ns. Check that they correspond to the car specification.
If a control module or software does not correspond, replace with the correct version.

Continue - DONE
