FREEZE FRAME DATA

FREEZE FRAME DATA

NOTICE:

  • 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 specification.
  • Turn the ignition switch on and park the vehicle on level ground. Check the freeze frame data by using the GTS.

(a) Check the freeze frame data on the GTS.
