 Lucas / TRW 5AS Body control module

 

The above picture is a TRW 5AS Body control module. It is fitted to Rover Mini / 100 / 200 / 400 / 25 / 45 / MGF from May 1995 to present. Earlier parts were branded Lucas rather than TRW. This unit control the cars security and other body control functions. Common failings of these units include Key fobs no longer working, and immobliser not functioning correctly. All 5ASs carry a date code on the right hand white label. Its in the form XX/YY, i.e. week number/year. 5ASs pre 1996 had an earlier RF (Radio Frequency) receiver on board. This was far more susceptible to 'jamming' from interfering radio signals than the later design. The result of this is that owners can experience apparent remote control failure in one location, but when the car is moved away from the source of interference, the system functions correctly again.Please call BBA for more information regarding a repair of your module.
