Circuit/System Verification

Ignition ON, observe all scan tool Driver Position Module seat switch parameters while pressing and releasing the each seat directional switch. The

reading should change between Inactive and Active.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the seat adjuster switch.

2. Verify the scan tool seat switch parameters listed below are Inactive.

* Front Vertical Upward Switch

* Front Vertical Downward Switch

* Rear Vertical Upward Switch

* Rear Vertical Downward Switch

* Recline Forward Switch

* Recline Rearward Switch

瀚慖f not the specified value, test the appropriate signal circuit listed below for a short to voltage. If the circuit tests normal, replace the

MSM.

* 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

* Horizontal rearward switch terminal C

* Recline forward switch terminal H

* Recline rearward switch terminal G

3. If all circuits test normal, test or replace the seat adjuster switch.

Component Testing

1. Ignition OFF, disconnect the harness connector at the seat adjuster switch.

2. Test for infinite resistance between each seat direction signal terminal listed below and the B+ terminal E with the switch in the open

position.

* Front vertical upward switch terminal A

* Front vertical downward switch terminal K

* Rear vertical upward switch terminal F
