СИСТЕМА ECD ДАННЫЕ ФИКСИРОВАННОГО НАБОРА ПАРАМЕТРОВ


  1. 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, as well as other data recorded at the time of a malfunction.

      Tech Tips

      If it is impossible to duplicate the problem even though a DTC is stored, confirm the freeze frame data.


    • B0025ZPE12
      *1 DTC is stored
      *2 0.5 seconds
      *3 Freeze frame data recorded

      The ECM records engine conditions in the form of freeze frame data every 0.5 seconds. Using an 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.
