I have been hard at work for the past few weeks at development on a series of Tools for the MKIII Range Rover. Progress has been surprisingly quick. I have been able to establish communications with every possible ECU contained in the MKIII. I have even been talking to some modules that are completely unknown to me. I hope to have a product for the MKIII EAS subsystem by the end of 2009.
Currently I am in the process of systematically triggering as many of the EAS faults as possible. When a fault condition is know, then I can compare the responses from the EAS computer. Over time, I will be able to piece together all of the EAS faults and the respective response from the EAS computer. It is a tedious process but the pace of discovery speeds up as I move along. Once the protocol is understood, I will build the system into a microprocessor.
