• Ignition off.

  Check the connectors and the side acceleration sensor for damage. Check also that the side acceleration sensor is correctly fitted and that the bracket is attached properly.

  HINT: With the ignition on, check the side acceleration sensor by testing the side acceleration sensor signal between: 

  • #9 and #40 on the test box. The voltage should be approximately 2.5 V.
  • #9 and #25 on the test box. The voltage should be approximately 5 V.

  Do the necessary corrective action.

  Additional information: 

  • To connect the test box, see Connecting the ABS/DSTC breakout box .
  • To replace the side acceleration sensor, see Replacing the yaw rate sensor (1) and the lateral acceleration sensor in the center console (DSTC) .
  • For information on signals, see Signal specification, ABS/DSTC (dynamic stability and traction control) control module .
