< FUNCTION DIAGNOSIS >
DIAGNOSIS SYSTEM (BCM)
FREEZE FRAME DATA (FFD) AND IGN COUNTER
Freeze Frame Data
The BCM records the following condition at the moment a particular DTC is detected.
 Vehicle Speed
 Odo/Trip Meter
 Vehicle Condition (BCM detected condition)
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.
