Memory Switch

  1. Disconnect the harness connector at the heated/cooled seat switch.
  2. Test for infinite resistance between the memory switch signal circuit terminal 9 and the switch supply voltage circuit terminal 1.
    • If not infinite, replace the heated/cooled seat switch.
  3. Test the resistance between terminal 1 and terminal 9 while pressing the memory 1, memory 2 and EXIT buttons. Compare the resistance readings to the values in the Memory Switch Values table below.
    • If the resistance is not within the specified range, replace the heated/cooled seat switch.
