FREEZE FRAME DATA

1. FREEZE FRAME DATA

NOTICE:

Freeze frame data values will vary depending on the measurement conditions, surroundings, or vehicle conditions. For this reason, there may be a problem even when the values are within specifications.
Turn the ignition switch to ON and park the vehicle on level ground. Check the freeze frame data by using the Techstream.

(a) Turn the ignition switch off.

(b) Connect the Techstream to the DLC3.

(d) Turn the Techstream on.

(e) Check the freeze frame data on the Techstream.
