Freeze Frame Data (FFD)

The following vehicle status is recorded when DTC is detected and is displayed on CONSULT.

Freeze Frame Data Item Unit Display item
Original Odometer Value km Display the odometer value stored when the respective DTC is detected for the first time.
Most Recent Odometer Value km Display the odometer value stored when the respective DTC is detected for the last time.
Frequency Counter 0 - 255 Display the frequency counter defined as the total number of times the DTC status has changed from "stored - not active" to "active".
Ignition cycle counter 0 - 255 Display the number of consecutive operation cycles recorded since a DTC first became stored -not active and is no longer an active DTC. This information is needed for Self-healing functionality.
MELCO code first occurrence Refer to the following table. Display the MELCO code stored when the respective DTC is detected for the first time.
BATTERY VOLTAGE-FIRST OCCURRENCE V Display the battery voltage value stored when the respective DTC is detected for the first time.
TSM first occurrence V Display the torque sensor main signal value stored when the respective DTC is detected for the first time.
TSS first occurrence V Display the torque sensor sub signal value stored when the respective DTC is detected for the first time.
Target current first occurrence A Display the target current value stored when the respective DTC is detected for the first time.
Measured current first occurrence A Display the measured current value stored when the respective DTC is detected for the first time.
Vehicle speed first occurrence km/h Display the vehicle speed stored when the respective DTC is detected for the first time.
