Check Of Freeze Frame Data
To detect fault and set the DTC, the gateway-ECU (for BSW) obtains data before the confirmation of the DTC and data when the DTC is confirmed, and then stores the current condition of the gateway-ECU (for BSW). By analyzing each data from scan tool (M.U.T.-IIISE), the troubleshooting can be performed more efficiently. Display items of the freeze frame data are as follows.
