Memory Switch

  1. Disconnect the X4 harness connector at the DDM.
  2. Test for infinite resistance between the memory switch signal circuit terminal 5 and the switch supply voltage circuit terminal 14.
    • If not infinite, replace the memory seat adjuster switch.
  3. Test the resistance between terminal 5 and terminal 14 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 memory seat adjuster switch.
