SELF-DIAGNOSIS RESULTS
DISPLAY ITEM LIST
NOTE:
●
If park position switch error is detected, manual adjustable pedal operation cannot be performed when
ignition switch turns ON.
●
The displays of CAN communication and park position switch display error detecting condition from mem-
ory 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 park position 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”.
