twrheuark Posted March 21, 2010 Share Posted March 21, 2010 I have a 1996 ES 300. A couple of weeks ago I disconnected the battery cable to reset the ECM. after doing that the ECM now gives a loud beep everytime you start the car. The car operates fine and there are no fualt codes. Can anyone tell me how to get rid of this beep? Thanks Tim Quote Link to comment Share on other sites More sharing options...
