This function is used to read the version information of system mode, vehicle
VIN, software and ECU.
B. Read Fault Code
This function displays the detailed information of DTC records retrieved from the
vehicle’s control system.
*Note: Retrieving and using DTCs for troubleshooting vehicle operation is only one
part of an overall diagnostic strategy. Never replace a part based only on the DTC

must be followed to confirm the location of the problem. This information can be found
in the vehicle’s service manual.
On the diagnostic function selection screen, tap “Read Fault Code”, the screen
will display the diagnostic result.
