FREEZE FRAME DATA

NOTICE:
  1. It is difficult to show the specified values (judgment values) clearly because freeze frame data values change significantly due to differences in measurement conditions, surroundings, or vehicle conditions. For this reason, there may be a problem even when the values are within specifications.
  2. Turn the ignition switch to ON and park the vehicle on level ground. Check the freeze frame data by using the intelligent tester.

  1. Turn the ignition switch off.

  2. Connect the intelligent tester to the DLC3.

  3. Turn the ignition switch to ON.

  4. Turn the tester on.

  5. Check the freeze frame data by following the prompts on the intelligent tester display.
