Check Of Freeze Frame Data
The freeze frame data can be checked by using the scan tool (M.U.T.-IIISE).
When detecting fault and storing the DTC, the ECU connected to CAN bus line obtains the data before the determination of the DTC and the data when the DTC is determined, and then stores the ECU status of that time. By analyzing each data from scan tool (M.U.T.-IIISE), the troubleshooting can be performed more efficiently. The displayed items are as the table below.
DISPLAY ITEM LIST
| Item No. | Item name | Data item | Unit |
|---|---|---|---|
| 1 | Odometer | Total driving distance after the DTC is generated | km/mile |
| 2 | Ignition cycle | Number of times the ignition switch is turned "OFF (LOCK or ACC)" after the past failure transition | Number of counts. |
| 4 | Accumulated minute | Accumulative time for current malfunction of DTC | min |
