I need to replace the engine control unit, ECU, of my Honda Civic 2000, my car doesn't have an immobilizer, it starts with a basic metal key, so, do I need to program the used ECU replacement?
Unless its actually a 1999 then it should be equipped with a immobilizer. 2000+ Honda Civics all use transponders so if its actually a 2000 and one is starting with an all metal key then 1 of 2 things have happened.
- The ecu was modified and the immobilizer was tuned out or emulated inside the ecu.
- Someone has taped a key or transponder under the dash inside the antenna.
A proper ecu replacement will need to have the immobilizer tuned out again or either the ecu will need matching with the immobilizer system AND key with properly coded transponder inside. I usually prefer HDS (honda diagnostics software) or Autel's 908 but many tools can do these older Honda immo systems.
