If it will not reconnect after multiple attempts, turn off
the key, remove the USB cable, turn on the key, and
reinsert the USB cable to the laptop, and click the
“Connect” button in the IRIS window.
•
If it still will not reconnect, the ECU is corrupted. The
throttle body assembly must be removed and
replaced with a new functioning unit.
