See step  5

1. Check that the acceleration sensor (yaw rate sensor) has been installed properly.

   Refer to INSTALLATION [09/2018 - 10/2020] , or refer to INSTALLATION [10/2020 - 11/2021] , or refer to INSTALLATION [11/2021 - 10/2023]

   OK

   The sensor should be tightened to the specified torque.

   The sensor is not installed in a tilted position.
