I've replaced the RF receiver (the one located in the headliner, just in front of the rear sun roof) and still do not have any response to the key fobs. All other functions of the BCU are perfect and I've checked the wiring between the BCU and the receiver and there are no problems.
Of the three wires going to the RF receiver:
1. The black (blue cable with a shroud) goes to the earth point in the rear boot space.
2. The purple/slate-gray wire carries the power to the receiver (mine is showing a healthy 12.36 volts).
3. The black/brown wire carries the RF signal to the BCU with Logic 1 when the voltage > 6V and Logic 0 when the voltage <2V. With the alarm disabled via the EKA my unit is showing 11.44V (Logic 1).
Can anyone confirm if this is the correct behaviour or do I have an isolated BCU fault? I've checked the service manual and the Rave CD but they do not seem to give the correct logic states for operation.
