• Last five cancel (system cancel) causes are displayed.
• “CAUSE OF AUTO-CANCEL” displays times of ignition switch ON/OFF up to 254 maximum. 254 is kept though the number exceeds 254. The num ber returns to 0 when detecting the same cancellation causes.
SELF DIAGNOSTIC RESULT
For details, refer to CCS-56, "Diagnostic Trouble Code (DTC) Chart".
NOTE:
“DTC RESULTS” and “TIME” are indicated on “Self Diagnostic Result”. “TIME” is used as a reference data of
diagnosis. It shows when malfunction is detected.
“TIME” shows the following.
• 0: malfunction is detected at present (from malfunction detection to ignition switch OFF).
CAN communication ([U1000], [U1010])
• 1 ~ 39: Displays when it is normal at present and finds malfunction in the past. It increases like
0→ 1→ 2...38→ 39 after returning to the normal condition whenever IGN OFF→ ON. If it is over 39, it is fixed to
39 until the self-diagnostic results are erased. It retu rns to 0 when malfunction is detected again in the pro-
cess.
Other than CAN communication (other than [U1000], [U1010])
• 1 ~ 49: Displays when it is normal at present and finds malfunction in the past. It increases like 0→ 1→ 2...48→ 49 after returning to the normal condition whenever IGN OFF→ ON. If it is over 49, it is fixed to
49 until the self-diagnostic results are erased. It retu rns to 0 when malfunction is detected again in the pro-
cess.
