How to disable the anti-theft system on an old Elysee?
1 Answers
Old Elysee's transponder-based electronic anti-theft system is an additional security feature built upon the BOSCH MP5.2 fuel injection system, designed to lock and unlock the engine control unit (ECU) for vehicle anti-theft purposes. When inserting a correct key with transponder and turning to "M" position, the system automatically completes code matching to unlock the ECU, otherwise it cuts off ignition and fuel injection control to prevent engine starting. Extended information: Notes: The ECU compares the received ECM code with its stored ECM code. If codes mismatch, the ECU remains locked and transmits "locked" status to the electronic control box via CE line, triggering warning light flashes and buzzer alarms. Only with matching codes will the ECU unlock to enable engine start.
