3360266 - K03 SPEEDOMETER NOT WORKING

During driving the rev counter does not work, or it works irregularly.
The speed signal is supplied at the C-CAN network by the 'brakes node' and via the gateway for the 'body compter node' is made available to the 'instrument panel node' via the B-CAN network. It should be remembered that in the case of a C-CAN network error the signal is supplied by the 'brakes node' to the 'body computer node' via the 'vso' line and from the 'body computer node' is made available to the B-CAN network
