Body Control Module: Scan Tool Testing and Procedures
Check of Freeze Frame Data
CHECK OF FREEZE FRAME DATA
The freeze frame data can be checked by using the scan tool (general (Body and Chassis), How to Cope with Intermittent Malfunction).
When detecting fault and storing the DTC, the ECU connected to CAN bus line obtains the data before the determination of the DTC and the data when
the DTC is determined, and then stores the ECU status of that time. By analyzing the data from scan tool, the troubleshooting can be performed more
efficiently. The displayed items are as shown in the table below.
