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.

—: Undiagnosed

CAN COMMUNICATIONPFP:23710
System DescriptionNKS0034C
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
