  3. TROUBLESHOOTING PRECAUTIONS


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

      CAUTION:


      • B006ZQF

        Do not perform the rear brake inspection while either the skid control ECU (brake actuator assembly) connector or the negative (-) battery terminal are connected.

      • The rear disc brake piston could operate, resulting in an accident such as hands being caught.

    2. 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.

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

  4. HANDLING PRECAUTIONS


    1. 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 (electric parking brake switch assembly) to the lock side 2 times (2 lock operations).

      Tech Tips


      • 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 sensor assembly).

      • When the parking brake indicator (red) is illuminated after the electric parking brake switch (electric parking brake switch assembly) has been pulled to the lock side, the maximum amount of braking force is applied if the electric parking brake switch (electric parking brake switch assembly) is pulled to the lock side one more time.

    2. The parking brake indicator light blinks (red) when the ignition switch is turned to ON after replacing the skid control ECU (brake actuator assembly). Operate the electric parking brake switch (electric parking brake switch assembly) to turn off the parking brake indicator light.
