DESCRIPTION
The skid control ECU (brake actuator assembly) receives shift position signals from the ECM via CAN communication to control the electric parking brake system AUTO function (IG-OFF linked function).

Then, if the shift lever is moved to P, the AUTO function (IG-OFF linked function) automatically operates to apply the electric parking brake.
