Make sure you are grounded out so you don't create an electrostatic discharge while handling the ECM as this can damage it. Make sure the battery is disconnected before you unplug or plug in the ECM to prevent electrostatic discharge or power surge that might damage the ECM. Make sure the ECM gets properly grounded when you reinstall it. The ECM will need to relearn when you reconnect it, just go for a drive of varying speed over 35 MPH and highway speed for about 1/2 hour.
