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 moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
Tech Tips
If it is impossible to duplicate the problem even though a DTC is output, confirm the freeze frame data.
| *1 | DTC stored |
| *2 | 0.5 seconds |
| *3 | Freeze frame data which can be read |
The ECM records engine conditions in the form of freeze frame data every 0.5 seconds. Using the GTS, 5 separate sets of freeze frame data can be checked.
3 data sets from before the DTC was stored
1 data set from when the DTC was stored
1 data set from after the DTC was stored
These data sets can be used to simulate the condition of the vehicle from 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.
