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. |
| MCU temperature first occurrence | °C | Display the temperature inside control unit stored when the respective DTC is detected for the first time. |
| Engine running first occurrence | Engine off Engine on |
Display the engine status stored when the respective DTC is detected for the first time. |
| Ignition status first occurrence | IGN OFF IGNITION ON |
Display the ignition switch status stored when the respective DTC is detected for the first time. |
| EPS assistance state first occurrence | Assistance off Assistance on |
Display the EPS assistance status stored when the respective DTC is detected for the first time. |
| Derating mode first occurrence | Derating off Derating on |
Display the derating mode stored when the respective DTC is detected for the first time. |
| APC control state first occurrence | APC control off APC control on |
Display the APC control status stored when the respective DTC is detected for the first time. |
| Add on control state first occurrence | Add-on control off Add-on control on |
Display the Add on control status stored when the respective DTC is detected for the first time. |
