Memory Switch
- Disconnect the X4 harness connector at driver door switch.
- Test for infinite resistance between the signal circuit terminal 5 and the 12 V reference circuit terminal 14 with the switch in the open position.
- If not the specified value, replace the memory switch.
- 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 switch.
