Title: HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM (for LITHIUM-ION BATTERY with PA10): FREEZE FRAME DATA; 2023 - 2025 MY Corolla HV [09/2022 -        ]

FREEZE FRAME DATA

FREEZE FRAME DATA

HINT:

The hybrid vehicle control ECU records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. It can be used for estimating or duplicating the vehicle conditions that were present when the malfunction occurred.

(a) Select a DTC in order to display its Freeze Frame Data.

Powertrain > Hybrid Control > Trouble Codes

(b) Check the freeze frame information recorded with the DTC.
