Toyota Yaris: Dynamic Radar Cruise Control System / Freeze Frame Data

Toyota Yaris XP210 (2020-2024) Reapir and Service Manual / Engine & Hybrid System / Cruise Control / Dynamic Radar Cruise Control System / Freeze Frame Data

FREEZE FRAME DATA

CHECK FREEZE FRAME DATA

HINT:

The ECU records vehicle and driving condition information as freeze frame data the moment a DTC is stored.

(a) Enter the following menus: Powertrain / Radar Cruise 1*1 or Radar Cruise 2*2 / Trouble Codes.

*1: Output from the ECM
*2: Output from the millimeter wave radar sensor assembly

(b) Select the DTCs (with snow icon) for which freeze frame data is recorded.

Powertrain > Radar Cruise1 > Trouble Codes Powertrain > Radar Cruise2 > Trouble Codes

NOTICE:

The operating conditions the moment a DTC is stored are recorded as freeze frame data. Furthermore, only the latest 3 DTCs can be stored by the millimeter wave radar sensor assembly.
