Electric Parking Brake System AUTO Function Circuit |
DESCRIPTION
The No. 2 skid control ECU (brake actuator assembly) receives shift position signals from the hybrid vehicle control ECU via CAN communication to control the electric parking brake system AUTO function (shift-linked).
The electric parking brake system AUTO function (shift-linked) is automatically disabled when the ignition switch is ON, the brake pedal is depressed and the shift lever is moved out of P. Then, if the shift lever is moved to P, the AUTO function (shift-linked) automatically operates to apply the electric parking brake.
WIRING DIAGRAM
CAUTION / NOTICE / HINT
NOTICE:
- The AUTO function (shift-linked) will not be automatically disabled when the ignition switch is ON, the brake pedal is depressed and the shift lever is moved out from P if the integration control and panel assembly is moved to the engage side. The AUTO function (shift-linked) will not automatically operate to apply the electric parking brake when the shift lever is moved to P if the integration control and panel assembly is moved to the release side.
- To ensure that the electric parking brake does not operate, wait for 3 minutes or more with the ignition switch off, the driver door closed, and the brake pedal not depressed, then disconnect each connector, fuse and relay.
-
After replacing the No. 2 skid control ECU (brake actuator assembly), perform "Calibration".

- When replacing the No. 2 skid control ECU (brake actuator assembly), operate the electric parking brake switch (integration control and panel assembly) as the parking brake indicator light blinks when the ignition switch is first turned ON.
