IGN Counter
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.
