Brake Actuator: Installation

WARNING: This page is about a different car, the 2008 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: In case of replacing the skid control ECU, perform the zero point calibration of the steering angle sensor, master cylinder pressure sensor, and yaw rate and deceleration sensor (see CALIBRATION ).

INSTALL VSC ACTUATOR WITH ACTUATOR BRACKET ASSEMBLY
1. Install the VSC actuator with actuator bracket with the 3 nuts.
  NOTE: Do not drop the actuator. If dropped, replace it.
2. Tighten the 3 nuts uniformly in alphabetical order.
  Torque: 22 N*m (224 kgf*cm, 16 ft.*lbf)
