IGN counter indicates the number of times that ignition switch is turned ON after DTC is detected.
The number is 0 when a malfunction is detected now.
The number increases like 1 → 2 → 3...38 → 39 after returning to the normal condition whenever ignition
switch OFF → ON.
The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.

BCM : DescriptionINFOID:0000000003794769
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detectability. Modern vehi-
cles are equipped with many electronic control units, 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.
