Viper Competition coupe to ADL3

[MartijnV]

Our ADL3 functioned fine in our VCC. But since last weekend it had no connection between the ecu and the ADL3.
We can make a readout of the ecu with an OBD2, but I can't see anything on the dash.

Now I've read in the VCC manual that before you make a readout with OBD you should remove the CIM.
Now I think that we damaged the CIM, because that's how the ADL get's its communication.

Is there a way I can check the CIM?
