Lost Central locking and window washers

[Bash]

The other day I tryed to use my windscreen washers however they did not work. When I got out my car to lock it the central locking did not work, I checked all the fuses but nothing had blown and everything was ok. The button on the RCL doesnt work neither does the one inside the car, the lights flash but no locking. I tryed holding down the internal central locking button till i herd the pips but still nothing. It is really starting to confuse me now, anyone got any ideas?

UCH


The UCH (Universal Car Harness) is an electronic control module that is fitted to many late model Renaults (early 2000's onwards.) It is responsible for controlling many of the non-engine related functions of the car, such as central locking, electric windows, and even some of the lights (e.g. indicators.)

A brand new UCH is supplied with a blank memory. This must be coded (using the Renault Clip computer) to match the serial number of the ECU and key/card before it will work with the car. The memory can only be written once, so a used UCH cannot be taken from a donor vehicle to be used in another unless the ECU and keyfobs/cards are also transferred.
