• Ignition off
• Connect the breakout box.

  Check the wiring between the connector for the active yaw control sensor

  • terminal #1 and control module terminal #25 (terminal #A25)
  • terminal #2 and control module terminal #29 (terminal #A29)
  • terminal #3 and control module terminal #6 (#A6)
  • terminal #5 and control module terminal #39 (terminal #A39).

  check for an open-circuit or short-circuit to ground and for a short-circuit to each other.

  Also check that the active yaw control sensor is correctly installed and that the bracket is secured.

  If the cables are OK, try a new active yaw control sensor.
