Toyota Yaris: Stop And Start System / Diagnosis System
DIAGNOSIS SYSTEM
DESCRIPTION
When troubleshooting a vehicle with a diagnosis system, the only difference from the usual troubleshooting procedure is connecting the GTS to the vehicle and reading various data output from the engine stop and start ECU.
The engine stop and start ECU records DTCs when it detects a malfunction in itself or in its circuits.
To check for DTCs, connect the GTS to the DLC3 on the vehicle. The GTS can be used to clear the DTCs, activate various actuators, and check the Freeze Frame Data and Data List.

FREEZE FRAME DATA
The ECU 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, as well as other data recorded at the time of a malfunction.
