To reset the ECU (Engine Control Unit) on a 2001 Ford Expedition, disconnect the negative battery cable and wait for about 15 minutes to allow any residual power to drain. Reconnect the negative battery cable and turn the ignition key to the "On" position without starting the engine for about 10 seconds, then turn it off. This process helps the ECU to reinitialize and clear any stored error codes. Always ensure you have any necessary radio codes or settings saved before performing this reset, as they may be lost during the process.
