FREEZE FRAME DATA
DESCRIPTION
The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was moving or stationary, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
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 the Techstream, 5 separate sets of freeze frame data can be checked.
- 3 data sets before the DTC was stored.
- 1 data set when the DTC was stored.
- 1 data set after the DTC was stored.
These data sets can be used to simulate the condition of the vehicle around the time of the occurrence the malfunction. The data may assist in identifying the cause of the malfunction, and judging whether it was temporary or not.
