DESCRIPTION OF “CAN DIAG SUPPORT MNTR” SCREEN FOR FRONT AIR CONTROL
Display Results (Present)
lOK: Normal
lUNKWN: The diagnosed unit does not transmit or receive the applicable data normally.
l–: There is no received unit or the unit is not in the condition that reception diagnosis is performed.
Display Results (Past)
lOK: Normal
l0: There is malfunction now.
l1 ~ 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.
l–: Undiagnosed

System DescriptionEKS00PDP
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.
