Toyota Yaris: Charging System / 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.
PENDING FREEZE FRAME DATA
HINT:
Pending freeze frame data is stored when a 2 trip DTC is first detected during the first trip.
(a) Connect the GTS to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the GTS on.
(d) Enter the following menus: Powertrain / Engine / Trouble Codes.
(e) Select a DTC in order to display its pending freeze frame data.
HINT:
-
Pending freeze frame data is cleared when any of the following occurs:
- Using the GTS, the DTCs are cleared.
- The cable is disconnected from the negative (-) battery terminal.
- 40 trips with the engine fully warmed up have been performed after the condition returns to normal. (Pending freeze frame data will not be cleared only by the system returning to normal.)
- With previous pending freeze frame data stored, if pending freeze frame data is newly stored when a 2 trip DTC is detected in the first trip, the old freeze frame data will be replaced with the new data of the newly detected DTC in the next trip.
LIST OF FREEZE FRAME DATA
(a) According to the display on the GTS, read the freeze frame data.

Toyota Yaris XP210 (2020-2025) Reapir and Service Manual: Brake Switch "A"/"B" Signal Cross Coupled (P05042B)
DESCRIPTION The stop light switch assembly is a duplex system that transmits two signals: STP and ST1-. These two signals are used by the ECM to monitor whether or not the brake system is working properly. If the signals, which indicate the brake pedal is being depressed and released, are detected simultaneously, the ECM interprets this as a malfunction in the stop light switch assembly and stores this DTC...
