Seat Switch Stuck Closed
Cause:
The switch is located in the seat cushion. The seat switch closes when the seat is sat in and opens when the
operator gets up. If the switch is closed for over 24 engine hours, this fault code will be recorded.
Possible failure mode:
1. Seat switch stuck closed.
2. Seat switch wiring circuit problems.
Solution:
Check the seat switch function.
Check the wiring from the instrumentation controller to the seat switch.
1. Check the seat switch function with the service tool. The seat switch status can be monitored through the
monitor screen of the service tool.
Click the button 'CHANGE PARAMETER SELECTIONS.'
When the 'PARAMETER LIST' screen shows up, select 'SEAT OPERATOR PRESENT SW' and add it to the
'VIEW LIST.'
Now you can monitor the function of the seat switch.
Sit down and then stand up a few times.
The seat switch should close when the seat is sat in and open when the operator gets up.
If the status on the screen changes with the operators position, the seat switch is functioning OK. The fault
code might be recorded for intermittent seat problems.
If the status on the screen does not change with the operator's position, there is a problem with the seat switch
or their wiring.
Go to the next Step.
