DESCRIPTION OF “CAN DIAG SUPPORT MNTR” SCREEN FOR ECM
Display Results (Present)

OK: Normal

UNKWN: The diagnosed unit does not transmit or receive the applicable data normally.

–: There is no received unit or the unit is not in the condition that reception diagnosis is performed.
Display Results (Past)

OK: Normal

0: There is malfunction now.

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 returns to 0
when malfunction is detected again in the process.
