You can expect the EIS module to be supported and installed on the following Chassis list: The EIS module is factory fitted to almost all models and we’re getting units sent in right across the board from C-Class C220 Mercedes to ML’s and E350 Mercedes. – Then and only then, when all three control units agree it is the correct authorised key being used, will it allow the “Turn & Start” function to be activated. The ESL system will then look to see if the Engine ECU (Electronic Control Unit) agrees that this is the authorised key being used. Each time the key is inserted, the EIS system will check the key and then ask the ESL (Electronic Steering Lock) system for verification that it accepts the correct key is being used. The vehicle will instantaneously carry out a sequence of test handshakes to ensure the correct key has been inserted. The key has a sequential code to ensure the vehicle is not stolen. It is more like a plastic lego-brick with what looks like an infra-red panel at the face of it which is inserted into the EIS socket on the dash. Under the steering wheel to find KESSY computer, dismantle the KESSY Module.
