3. Unplug the machine wire harness electrical connector from the seat switch
(Figure 124).
4. Connect a multimeter (ohms setting) across the seat switch harness
connector terminals to check the continuity of the seat switch.
A. With no pressure on the seat, ensure that there is no continuity between
the harness terminals of the seat switch.
B. Press directly onto the seat switch through the seat cushion. Ensure that
there is continuity between the harness terminals of the seat switch as
the seat cushion approaches the bottom of its travel indicating that the
seat switch is functioning.
5. Replace the seat switch if testing determines that the switch is damaged.
6. If the seat switch testing is correct and the circuit problem still exists, check
the machine wire harness; refer to the Electrical Schematics and Wire
Harness Drawings/Diagrams in
7. After you complete the seat switch testing, connect the machine wire harness
