Circuit/System Verification
Ignition ON, observe the scan tool Seat Memory Control Module seat switch parameters listed below while pressing and releasing the appropriate
seat directional switch. The readings should change between Inactive and Forward/Rearward or UP/Down.
* Driver Seat Cushion Front Vertical Switch
* Driver Seat Cushion Rear Vertical Switch

Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the S64D driver seat adjuster switch.
2. Verify that all scan tool driver seat switch parameters listed below are Inactive:
* Driver Seat Cushion Front Vertical Switch
* Driver Seat Cushion Rear Vertical Switch
* Driver Seat Horizontal Switch
* Driver Seat Back Switch
瀚慖f not the specified value, test the appropriate signal circuit listed below for a short to ground. If the circuit tests normal, replace the K40
seat memory control module.
* Front vertical upward switch terminal A
* Front vertical downward switch terminal K
* Rear vertical upward switch terminal F
* Rear vertical downward switch terminal J
* Horizontal forward switch terminal D

3. If all circuits test normal, test or replace the S64D driver seat adjuster switch.
Component Testing
1. Ignition OFF, disconnect the harness connector at the S64D driver seat adjuster switch.
2. Test for infinite resistance between the ground terminal E and each seat direction signal terminal with the switch in the open position.
瀚慖f not the specified value, replace the S64D driver seat adjuster switch.
3. Test for less than 2 Ohms between the ground terminal E and each signal terminal with the appropriate switch in the closed position.
瀚慖f greater than the specified value, replace the S64D driver seat adjuster switch.
