• Ignition off
• Disconnect the contact reel from the steering wheel module (SWM)

  Measure the resistance between:

  • terminals #B1 and #B2
  • terminals #B1 and #B3
  • terminals #B2 and #B3.

  The resistance must be infinite.

  Check the cable between:

  • terminal #B1 and contact reel terminal #1
  • terminal #B2 and contact reel terminal #2
  • terminal #B3 and contact reel terminal #3.

  Check for an open-circuit.
