OBD II 291
FREEZE DATA
Press 4 to select <FREEZE DATA> from the <OBD II FUNCTIONS> menu. The
vehicle's ECU typically saves information about the state of the vehicle when a Diagnostic
Trouble Code (DTC) occurs. Freeze data is also referred to as Freeze Frame Data and can
be read by the Tester using the <FREEZE DATA> mode. You can select this mode from
the <OBD II FUNCTIONS> menu or you can select it from the DTC display mode. (Refer
to the <DTCs> description.) Freeze Data is also referred to as OBD II Mode 2.
If the vehicle contains more than one OBD II ECU, select the primary ECU for the display
of diagnostic information. Refer to Section 5.0: Displaying Data For Multiple ECUs for
more information.
FREEZE DATA DISPLAY
Freeze Data is only available for the first DTC which was detected by the vehicle. The
first parameter in the list is the DTC which caused the Freeze Data to be saved. The Freeze
Data is displayed in the same format as the All Data List format described in the <DATA
LIST> mode.
