Toyota RAV4 (XA40) 2013-2018 Service Manual: Freeze frame data
- Description
Freeze frame data records the engine conditions (fuel system, calculated load, engine coolant temperature, fuel trim, engine speed, vehicle speed, etc.) When a malfunction is detected. When troubleshooting, it can help determine if the vehicle was running or stopped, the engine was warmed up or not, the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.
Hint:
If it is impossible to duplicate the problem even though a dtc is detected, confirm the freeze frame data.
The ecm records engine conditions in the form of freeze frame data every 0.5 Seconds. Using the intelligent tester, 5 separate sets of freeze frame data can be checked.
- 3 Data sets before the dtc was set.
- 1 Data set when the dtc was set.
- 1 Data set after the dtc was set.
These data sets can be used to simulate the condition of the vehicle around the time of the occurrence of the malfunction. The data may assist in identifying the cause of the malfunction, and in judging whether it was temporary or not.

Check mode procedure
Hint:
Intelligent tester only:
compared to normal mode, check mode is more sensitive to
malfunctions. Therefore, check mode can detect the
malfunctions that cannot be detected by normal mode.

Cold and hot mean the temperature of the coils
themselves. Cold is from -10 to 50°c (14 to 122
°f) and hot is from 50 to 100°c (122 to 212°f).

When any dtc for the can communication system is output, first measure the
resistance between the
terminals of the dlc3 to specify the trouble area, and check that there is not a
short in the can main wire,
between the main wire, to +b, or to gnd.
