Replacing CDR23

code in the instrument cluster. If the codes correspond, the device is operational.
As soon as a match is found, the device is operational. No further checks are carried out as long as the device is not disconnected from the vehicle
electrical system.
If no match is found, the device switches off after 30 seconds and the 'PROTECTED' message appears in the display. The device is not operational. The
