General Description

The HECU interchanges requirement data with the 4WD ECU through CAN bus line for normal ABS control.
For example the HECU sends a control inhibition signal to 4WD ECU for normal ABS control in case of the ABS and 4WD control requested at the same time because wheel speed difference between front and rear wheel occurs.

DTC Description

The HECU checks absence of the 4WD message from the 4WD ECU for normal ABS control and sets this code if an 4WD ECU message is not received within predefined time.
The HECU checks the presence and specific contents of the 4WD1 message from the 4WD ECU and sets this code if there is an error in 4WD ECU message1.
