Hello,calling any old school Merc boys that may be familier with this one!! Alarm fob locks and unlocks car fine but wont unlock ECM(Mirror head LED's flashing alternatley). Merc HHTwin wont communicate with any systems other than ABS.Pulling me hair out as wisnet wont tell me(or at least i cant find)what gives the ECM a release code.Am guessing its the Infrared control mod(IR) behind the dash clocks. Also the millage stays illuminated perminantly on the speedo. Could it be a CAN fault stopping all these systems communicating?
