Electric Parking Brake System AUTO Function Circuit [02/2017 - ]: Description

The skid control ECU (brake actuator assembly) receives shift position information from the ECM via CAN communication.

In addition, front seat inner belt information and driver seat door courtesy switch information is received from the main body ECU (multiplex network body ECU).

The electric parking brake system AUTO function (shift-linked function) automatically releases the parking brake when the following conditions are met: 1) Ignition switch to ON, 2) brake pedal is depressed, and 3) shift lever is moved out of P. When the shift lever is moved to P with these conditions met, the function automatically locks the parking brake.

The electric parking brake system AUTO (shift-linked function) automatically engages the parking brake when the shift lever is moved to P and disengages the parking brake when the shift lever is moved out of P when the ignition switch to ON and the brake pedal is depressed.
