1-1. Diagnostic Speed Improvement
- Current: Increased time due to automatic retry of control units when fault code search fails
-
Improvement: User can choose whether to retry
There are two cases in which a communication failure pop-up may appear.
1) When the ECU that failed to communicate does not actually exist in the vehicle.
2) When performing a DTC search in 'Fast FCS', some ECUs do not support the 'Fast FCS' function, which may cause a communication failure pop-up as the image below. In this case, normal communication may be possible by running DTC Search in normal mode ━ select the checkbox shown in the image below and then click the OK button).
