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 intelligent tester.
- Connect the intelligent tester (with CAN VIM) to the DLC3.
- Turn the power switch ON (IG) and check the freeze frame data by following the prompts on the display of the intelligent tester.
