Thread: Is there a way to test the Key receiver in roof?

Does the light come on on the key fob? I bought a wide range signal detector to check, but experience suggests to me now that if the light comes on it is transmitting.

I had this problem when I bought my D2 and it was the receiver. I bought another one from a member of the forum and it worked.

I would think that there would be a momentary voltage from the sender wire of the receiver to the BCEM when the fob button is pressed.

Maybe find the input wire on the BCEM from the wiring diagram and check for a voltage while someone presses the fob or if you are a contortionist check at the receiver.

Hey mate yeah the signal detector is what I checked the keys with at M and R.
I will go looking for power at the receiver next and then like you said a signal leaving the unit when pressed.
Thanks

The Nanocom RF test will detect unpaired keys. Perhaps the issue is in the wiring to the receiver?
