Toyota Avalon (XX50) 2019-2022 Service & Repair Manual: Freeze Frame Data

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 reproduce the symptoms even though a DTC is stored, confirm the freeze frame data.
  • Freeze frame data is available in long and short forms.
