   -4. Use a torque wrench (C) and the socket (D) to rotate the detent shaft, and check that the detent shaft moves smoothly. Move it back and forth between the P position (E) and the P released position (F) several times.

   • -

     Operation angle: approx. 21 deg.

   • -

     Operation torque: approx. 4.0 N.m (0.41 kgf.m, 3.0 lbf.ft)

   -5. Check that the wheels are locked when putting the detent shaft in the P position. Additionally, check that the wheels rotate when putting the detent shaft in the P released position.

   Is the transmission park mechanism OK?

   YES 

   The transmission park mechanism is OK. Put the detent shaft in the P position, and replace the park pawl actuator .

   NO 

   Faulty transmission park mechanism. Replace the transmission (e-CVT) .
