Steering Column Tilt/Telescope Switch Test

Ignition OFF, disconnect the harness connector at the S71 Steering Column Tilt Wheel and Telescope Switch.
Test for infinite resistance between the ground terminal 1 and each signal terminal with the S71 Steering Column Tilt Wheel and Telescope Switch in the released position.
- If less than infinite resistance
  Replace the S71 Steering Column Tilt Wheel and Telescope Switch.
- Go to next step: If infinite resistance
Test for less than 2 Ω between the ground terminal 1 and each signal terminal with the S71 Steering Column Tilt Wheel and Telescope Switch in the pressed position.
- If 2 Ω or greater
  Replace the S71 Steering Column Tilt Wheel and Telescope Switch.
- Go to next step: If less than 2 Ω
All OK.
