Freeze Frame Data
NOTE:
- It is difficult to show the specified values (judgment values) clearly because freeze frame data values significantly change due to differences in measurement conditions, surroundings or vehicle conditions. Because of this reason, there may be a problem even when the values are within specifications.
- Turn the power switch ON (IG) and park the vehicle on level ground to check the freeze frame data using the Techstream.
- Connect the Techstream (with CAN VIM) to the DLC3.
- Turn the power switch ON (IG).
- Turn the Techstream on.
- Check the freeze frame data. Enter the following menus: Chassis / EMPS / Utility / Freeze Frame Data.
