tuner-automotive Posted December 15, 2006 Share Posted December 15, 2006 I did a search but found nothing. Anyway to reset the ECU on a 92 Legacy NA 2.2L 5spd? Quote Link to comment Share on other sites More sharing options...
Manarius Posted December 15, 2006 Share Posted December 15, 2006 Pull the battery cable for 45 minutes or pull the ECU fuse for 45 minutes. Put the car in neutral, put the ebrake on, put the fuse or cable back on, and start the car. Let it get to running temp or 10 minutes - whatever comes first. Then shut the car off. Do not touch the gas or anything. Quote Link to comment Share on other sites More sharing options...
Setright Posted December 15, 2006 Share Posted December 15, 2006 Or the factory manual method: Igniton - OFF Connect the black and green connectors under the steering column. Both are single wire, normal-state is disconnected. Igntion - ON Press the throttle to the floor. Lift it back to approx. half-way, hold it there for 2 seconds. Release throttle fully. Ignition - START! Let the engine run for a few seconds, the CEL will be off if there are no present faults. Start driving....sooner or later, within minutes, the CEL will flash at a steady rate, indicating the ECU is reset. Igntion -OFF Disconnect both green and black wires. DONE!

Manarius Posted December 15, 2006 Share Posted December 15, 2006 SetRight, that method only clears the codes, it does not reset the entire ECU. Quote Link to comment Share on other sites More sharing options...
Setright Posted December 15, 2006 Share Posted December 15, 2006 That is the method stated in the Factory Service Manual. Quote Link to comment Share on other sites More sharing options...
