PARKING BRAKE: ELECTRIC PARKING BRAKE SYSTEM (w/o Vacuum Brake Booster): PRECAUTION; 2022 - 2024 MY RAV4 RAV4 HV [12/2021

(a) When inspecting the rear brakes, disconnect the connector of the parking brake actuator assembly or disconnect the cable from the negative (-) auxiliary battery terminal.

CAUTION:

Do not perform the rear brake inspection while either the No. 2 skid control ECU (brake actuator assembly) connector or the negative (-) auxiliary battery terminal are connected.
The rear disc brake piston could operate, resulting in an accident such as hands being caught.

(b) When disconnecting a connector or removing a fuse or relay, make sure that the ignition switch has been off, the brake pedal has not been depressed, and the driver door has been closed for 4 minutes or more*.

*: The electric parking brake may still operate up to 60 minutes depending on the state of the vehicle after the ignition switch is turned off, so be sure to perform the work procedures with the vehicle on a level surface.

(c) If a component has been removed and installed, confirm that the system operates normally by checking for DTCs after installation has been completed.

(a) When tilting the vehicle to perform work after parking the vehicle on a level surface, the braking force may not be sufficient. Make sure to pull the electric parking brake switch (integration control and panel assembly) to the lock side 2 times (2 lock operations).

HINT:

The electric parking brake system determines the amount of force used to operate the parking brake according to the tilt angle detected by the deceleration sensor (airbag ECU assembly).
When the parking brake indicator is illuminated after the electric parking brake switch (integration control and panel assembly) has been pulled to the lock side, the maximum amount of braking force is applied if the electric parking brake switch (integration control and panel assembly) is pulled to the lock side one more time.

(b) The parking brake indicator light blinks when the ignition switch is turned to ON after replacing the No. 2 skid control ECU (brake actuator assembly). Operate the electric parking brake switch (integration control and panel assembly) to turn off the parking brake indicator light.
