FREEZE FRAME DATA

1.

DESCRIPTION
Freeze frame data record 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 replicate 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 an intelligent tester, 
five separate sets of freeze frame data, including the 
data values at the time when the DTC was set, 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 conditions 
of the vehicle around the time of the occurrence of the 
malfunction. The data may assist in identifying of the 
cause of the malfunction, and in judging whether it was 
temporary or not.
