Component Testing

Memory Switch

  1. Disconnect the harness connector X4 at driver door switch.
  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 switch.
  3. Test the resistance between terminal 14 and terminal 5 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 switch.
Memory Switch Values

Switch Position Resistance
Idle Infinite
Memory 1 2.03K-2.49K ohms
Memory 2 3.83K-4.69K ohms
Exit 9.32K-10.18K ohms
