• Ignition off

  Check the connectors and yaw rate sensors 1 and 2 for damage. Check that yaw rate sensors 1 and 2 are correctly installed and that the bracket is secured.

  HINT: Check the yaw rate sensors by measuring the signal to the sensors with the ignition switched on: 

  For yaw rate sensor 1 between: 

  • terminals #27 and #42 on the breakout box. The voltage must be 2.5 V.
  • terminals #11 and #27 on the breakout box. The voltage must be approximately 5 V.

  For yaw rate sensor 2 between: 

  • terminals #14 and #45 on the breakout box. The voltage must be approx. 2.5 V.
  • terminals #30 and #45 on the breakout box. The voltage must be approximately 5 V.

  Remedy as necessary.
