Keep the trip reset switch for 1 seconds or more.
Press the trip reset switch at least 3 times. (Within 7 seconds after the ignition switch is turned ON.)
"Work instruction code" is indicated in the top portion of information display and self - diagnosis is started.
The mode switches in the order shown below each time the trip reset switch is pressed.

NOTE:

If the trip reset switch is not operated for 20 seconds or more, the self - diagnosis mode is automatically cancelled.
