What does this fault code mean?
The additive dosing module (ADM) has registered that its software does not match the car's configuration. It checks its configuration ID against what the CEM sends on the CAN network, and the code is set on a mismatch or when communication with the CEM is broken. Because the module cannot communicate while the fault is active, the code can only be read if it is intermittent.
Possible causes
- A wrongly matched configuration ID, for example from a second-hand module with other software or hardware
- Open circuit in the CAN wire between the module and the CEM
What you can do
- 1Check whether the ADM module has recently been replaced, especially if it is second-hand, and whether the correct software was downloaded
- 2Read the codes in the CEM and deal with any communication faults first
- 3Check that the wire between the module and the CEM has no breaks and that the connectors are secure
- 4Have a workshop download the correct software if it does not match the car
- 5Clear the code and check that it does not return
Symptoms you may notice1
- No clear symptoms for the driver
What the fault can affect1
- The module answers diagnostic commands, but normal CAN communication does not work
General guidance for car owners. Diagnosis on the car can point to a different cause.
