Toyota Avalon Service & Repair Manual: Freeze Frame Data

FREEZE FRAME DATA

FREEZE FRAME DATA

HINT:

  • When a DTC is stored, the freeze frame data stores the current vehicle (sensor) state as.
  • The freeze frame data cannot be cleared or updated until the recorded DTCs are cleared.

(a) Using the Techstream, the state of the vehicle (sensors) when the system is operating or when a DTC was stored can be checked.
