Installation [12/2023 - ]: Procedure

HINT: 

• Perform this procedure only when replacement of the shift control actuator seal is necessary.
• As a new shift control actuator assembly has the shift control actuator seal already installed, it is not necessary to install a shift control actuator seal if a new shift control actuator assembly is used.

   1. Clean and degrease the installation surface of the shift control actuator seal and contact surface of the hybrid vehicle transaxle assembly.
      NOTE:

      Do not use a sharp tool such as a scraper.

   2. Install a new shift control actuator seal to the shift control actuator assembly.

NOTE: When disconnecting a wire harness of any component connected to the supply power of the integrated capacitor (integration control supply) or when removing the integrated capacitor (integration control supply), make sure to wait 5 minutes or more after turning the ignition switch off for self-diagnosis to complete and the voltage of the integrated capacitor (integration control supply) to discharge. Do not rotate the spline part (*a) of the shift control actuator assembly. Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002 Make sure to engage the parking lock before performing this procedure. Make sure that the wheels of the vehicle are unable to rotate with the parking brake released.

   *a	Spline Portion of Shift Control Actuator Assembly	*b	Not P Position
   *c	P Position	*d	20.6°
   *e	2-flats Portion of Parking Lock Shaft	*f	Spline Portion of Parking Lock Shaft
   *g	Rotate Approximately 20°	-	-

   1. Check the spline portion (*a) of the shift control actuator assembly.
      • If the spline portion is not in the P position, perform step (ii).
      • If the spline portion is in the P position, perform step (iii).
   2. Using a pair of pliers, grip the spline portion (*f) of the parking lock shaft that has been wrapped with a cloth or other material and rotate it approximately 20° in the direction shown by the arrow in the illustration to release the parking lock.
      NOTE:

      • Do not rotate the wheels of the vehicle.
      • Do not grip the 2-flats portion (*e) of the parking lock shaft.
      • Make sure to use a cloth or other material to prevent damage to the spline portion (*f) of the parking lock shaft.
   3. Temporarily install the shift control actuator assembly to the hybrid vehicle transaxle assembly with the 3 bolts.
   4. Fully tighten the 3 bolts.

      Torque: 17.5 N.m (178 kgf/cm, 13 ft.lbf) 

   5. Connect the 2 shift control actuator assembly connectors.
      NOTE:

      Make sure to perform actuator position learning after removing and installing the shift control actuator assembly.

Torque: 19.5 N.m (199 kgf/cm, 14 ft.lbf)
