- 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 engine switch is turned off.
- *: The electric parking brake may still operate up to 60 minutes depending on the state of the vehicle after the engine 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.
