Was bedeutet der Fehlercode?
The engine control module (ECM) compares its configuration ID with the one the central electronics control module (CEM) sends out on the CAN network. The code is set when the IDs do not match, and also when communication with the CEM is or has been interrupted. Although the code is titled invalid data received, it concerns the configuration ID and the communication with the CEM.
Mögliche Ursachen
- Wrong CAN configuration ID because the module is not intended for the car, for example a used module with different software or hardware
- Break in the CAN wires between the engine control module and the CEM
Was Sie tun können
- 1Read the codes in the central electronics control module and other control modules on the CAN network, and fix communication faults first
- 2Check the CAN connectors between the engine control module and the central electronics control module for oxidation and loose contacts
- 3Use a multimeter to check that the CAN wires have no break or short to ground or supply voltage
- 4Clear the code, start the engine and check whether it is stored again
- 5If the engine control module has been replaced recently: have a workshop check that it is intended for this car and has the right configuration
