Seat Memory Switch

Ignition OFF, disconnect the harness connector at the S47 Seat Memory Switch.
Test for infinite resistance between each signal terminal listed below and the low reference terminal 1 with the switch in the open position.
- Terminal 5
- Terminal 6
- If less than infinite resistance
  Replace the S47 Seat Memory Switch.
- Go to next step: If infinite resistance
Test for less than 4 Ω between the signal terminal 5 and the low reference terminal 1 while pressing the memory SET button.
- If 4 Ω or greater
  Replace the S47 Seat Memory Switch.
- Go to next step: If less than 4 Ω
Test for 573 - 701 Ω between the signal terminal 6 and the low reference terminal 1 while pressing the memory 1 button.
- If not between 573 - 701 Ω
  Replace the S47 Seat Memory Switch.
- Go to next step: If between 573 - 701 Ω
Test for 1800 - 2201 Ω between the signal terminal 6 and the low reference terminal 1 while pressing the memory 2 button.
- If not between 1800 - 2201 Ω
  Replace the S47 Seat Memory Switch.
- Go to next step: If between 1800 - 2201 Ω
Test for 5.52k - 6.73 kΩ between the signal terminal 6 and the low reference terminal 1 while pressing the Exit button.
- If not between 5.52k - 6.73 kΩ
  Replace the S47 Seat Memory Switch.
- Go to next step: If between 5.52k - 6.73 kΩ
All OK.
