Honda common ECU failure symptoms


ALL HONDA FUEL INJECTION MODELS (esp. Civic and Accord - all years)
- Intermittent poor or non start. REPLACE fuel injection system relay!

Honda Prelude fitted with electronic 4 wheel steering are coming to our attention for fail with the following symptoms;

SYMPTOMS


    1) 4 wheel steering check/warning light illuminates continuously and 4 wheel steering does not operate (rear wheels REMAIN STRAIGHT AHEAD under all vehicle operating conditions). Vehicle fails annual roadworthiness test. Initially this would be an intermittent fault condition. Sometimes has fault code 44.

DIAGNOSTIC CHECKLIST


    1) Check for failure to maintain a consistent steering wheel angle when driving straight ahead with steering sensor fault code 25. This is NOT an ECU fault if driver has to correct steering when driving straight ahead. This fault is most probably caused by steering or suspension bush collapse. Please email us if you have successfully diagnosed or repaired this condition.

For ECU repair and rebuild quotation please use form found on this page. Questions relating to electronic fuel injection/engine management can be left blank. (we are as surprised as owners that this ECU, built to engineering standards that would not be out of place on the Space Shuttle, should fail early!)
