BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS  ELECTRONICALLY CONTROLLED BRAKE SYSTEM(for HEV Model)  DTC CHECK / CLEAR  


HINT:
·

DTCs which are stored in the skid control ECU can be displayed on the GTS. The GTS can display the confirmed and permanent DTCs.

·

If a malfunction is detected during the current driving cycle, confirmed and permanent DTCs are stored.

·

Confirmed DTCs can be cleared by using the GTS. However, permanent DTCs cannot be cleared using the GTS.

·

After clearing confirmed DTCs using the GTS, permanent DTCs can be cleared when the system is determined to be normal for the relevant DTCs and then the universal trip is performed. The driving pattern to obtain a normal judgment is described under the "Confirmation Driving Pattern" for the respective DTC.

To clear permanent DTCs, all of the following conditions must be are met:

-

There is a history that universal trip driving was performed.

-

The vehicle has been judged as normal for 1 trip.

-

No malfunctions are detected.
