TROUBLESHOOTING PRECAUTIONS
(a) When inspecting the rear brakes, disconnect the connector or disconnect the cable from the negative (-) battery terminal in order to shut off the supply of electrical power.
CAUTION:
- Do not perform the rear brake inspection while either the connector or the negative (-) battery terminal are connected.
- The rear disc brake piston could operate, resulting in an accident such as hands being caught.
(b) The electric parking brake may still operate for 20 seconds* after the ignition switch is turned off.
- *: 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) When any parts have been removed or installed, check for DTCs after completion of installation to confirm that the system is operating correctly.
HINT:
After performing work procedures such as installation, if the parking brake indicator light (red) is blinking, the parking brake must be released.
HANDLING PRECAUTIONS
(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 operate the electric parking brake switch to the lock side 2 times.
HINT:
- When the parking brake indicator light is illuminated after the electric parking brake switch has been operated to the lock side (first time), the maximum amount of braking force is applied if the electric parking brake switch is operated to the lock side one more time (second time).
- The electric parking brake system determines the amount of force used to operate the parking brake according to the tilt angle detected by the acceleration sensor (airbag sensor assembly).
(b) After replacing the skid control ECU (brake actuator assembly), the parking brake indicator light blinks when the ignition switch is turned to ON for the first time. To turn off the parking brake indicator light after replacing the skid control ECU (brake actuator assembly), operate the electric parking brake switch to the lock side then to the release side.
