Title: PARKING BRAKE: ELECTRIC PARKING BRAKE SYSTEM (w/ Vacuum Brake Booster): Electric Parking Brake System AUTO Function Circuit; 2021 - 2024 MY RAV4 RAV4 HV [08/2020 -        ]

Electric Parking Brake System AUTO Function Circuit

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).

The electric parking brake system AUTO function (IG-OFF linked function) 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 (IG-OFF linked function) automatically operates to apply the electric parking brake.

CAUTION / NOTICE / HINT

NOTICE:

  • The AUTO function (IG-OFF linked function) 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 electric parking brake switch (integration control and panel assembly) is moved to the engage side. The AUTO function (IG-OFF linked function) will not automatically operate to apply the electric parking brake when the shift lever is moved to P if the electric parking brake switch (integration control and panel assembly) is moved to the release side.
  • The electric parking brake may still operate up to 20 seconds after the ignition switch is turned off. Before disconnecting connectors or fuses, turn the ignition switch off and wait 20 seconds or more.
  • After replacing the skid control ECU (brake actuator assembly), perform acceleration sensor zero point calibration and store system information memorization.

  • When replacing the 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 to ON.
