securely connected to the vehicle's DLC.
3. Turn the ignition off and wait for about 10 seconds.

is too slow to respond to requests, you need to reset the Scan Tool:
1. Press and hold the POWER button for at least 2 seconds.
2. Turn the ignition off and wait for about 10 seconds.
Turn the ignition back to on and continue the testing.
