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”.
