SELF-DIAGNOSIS RESULTS

DISPLAY ITEM LIST

NOTE:

If detection switch error is detected, manual adjustable pedal operation cannot be performed when igni-
tion switch turns ON.

The displays of CAN communication and detection switch display error detecting condition from memory
erase to the present on “TIME”.

If error is detected in the past and present error is detected, “CRNT” is displayed.

If error is detected in the past and present error is not detected, “PAST” is displayed.

If error has never been detected, nothing is displayed on “TIME”.

Any items other than CAN communication and detection switch count error detection frequency occurred
after erase history to “1-127”.

If error was detected in the past, error detection frequency from memory erase to the present is displayed
on “TIME”.

If error has never been detected, nothing is displayed on “TIME”.

Can clear the detected memory.
Normal: Clear memory in normal condition, history is erased and nothing is displayed on “TIME”.
Error: Clear memory in error condition, error is detected again and “1” is displayed on “TIME”.
