SELF-DIAGNOSIS RESULTS
HOW TO READ SELF-DIAG RESULTS
NOTE:
CAN communication malfunction and detention switch malfunction are displayed on “TIME”. (1)
–If error is detected in the present, “CRNT” is displayed.
–If error is detected in the past (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 malfunction and detention switch malfunction are counted. (2)
–If error is detected, error detection frequency is displayed from “1” to “127” 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”.
