1) Disconnect the negative battery cable.
2) Turn the headlight switch on.
3) Wait 10 minutes.
4) Turn the headlight switch off.
5) Reconnect the battery cable.

Your ECM is now reset.

Take care,

After you finish setting them, you then reset your ECM. You should also do the following relearn procedure:

After resetting the ECM,

1) Start the engine, and allow it to idle for 1 minute.
2) Shut it off, and wait 10 seconds.
3) Start the engine, and turn on the headlights on high, and your a/c, with the fan on high, and let it idle for 1 minute.
4) Turn all the accessories off, and turn the engine off, and wait 10 seconds.
5) Start the engine, and make it idle @ 2000 rpm for 1 minute.
6) Shut it off, and wait 10 seconds.
7) Start the engine, and turn on the headlights on high, and your a/c, with the fan on high, and make it idle @ 2000 rpm for 1 minute.
8) Turn all the accessories off, and turn the engine off, and wait 10 seconds.

This is the best way to relearn the ECM, but you should take a 10 minute test drive afterwards to make sure all is well.

Take care,
~Chris
