Installation Notes
Physical replacement is straightforward for qualified mechanics or experienced DIYers: disconnect the battery, remove trim and ECU mounting screws, unplug the wiring harness and fit the unit in reverse order. After fitting most vehicles require ECU coding/programming and immobiliser synchronization using a professional diagnostic tool (for example DiagBox, Lexia or PP2000). If coding is not completed the engine may not start or fault codes may persist. Always verify that product codes match your vehicle before installation.
