To reset the computer on a 1997 Concorde with a 3.5L V6 engine, you can disconnect the negative battery cable for about 15 minutes. This will clear the stored trouble codes and reset the engine control module (ECM). After reconnecting the battery, start the engine and allow it to idle for a few minutes to let the ECM recalibrate.
