Radio Code & CANCHECK Repair Service

Alfa Romeo 940
Bosch

As originally fitted to the :

Alfa Romeo Giulietta


If you are trying to fit this radio to a different vehicle, then you may find yourself with the Error message of "CANCHECK". As well as having a conventional Radio Security Code number, this stereo is also electronically paired, or "Married" to the engine management system of the vehicle it came out of using very sophisticated CAN-BUS system technology.

When it is first powered up, it will communicate with the vehicle, and a message of "WAIT" will appear on the display whilst this process is in operation. If communication has been successful, it will prompt for the Code number to be entered in the normal way.

However, if removed and refitted into a different vehicle other than the original one, it will not recognize the encrypted CANBUS identification of the new car, and will instead display an error message of "CANCHECK" or "BLOCKED/WAIT" or "CODE ERROR".

This Radio cannot therefore be transferred from one car to another, unless it has first been reset back into its original "Delivery Mode" with the CAN-BUS data memory reprogrammed for use with the new vehicle.

Alfa Romeo Dealers may tell you that this stereo cannot be reprogrammed to go into another vehicle, but then thats what they said about other models, before we managed to reset the CAN-BUS system !!

We can reset the CANCHECK Error message for this radio, and return it with a Code number allowing it to be used in a different vehicle, but you will need to send the unit to our workshop for this work to be carried out. Approx turnaround time is 48 hours from receipt to dispatch.

Removal of the radio is fairly complex. Please consult your service manual for details on how to remove this.
