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
* 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
瀚慖f not the specified value, replace the seat adjuster switch.
3. Test for less than 1 ohm between each seat direction signal terminal listed below and the B+ terminal E with the switch in the closed position.
* 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
瀚慖f greater than the specified range, replace the adjuster switch switch.
