Remote Set Switch Failure
Possible failure modes:
1. Remote set switch failed.
2. Bad connection between the armrest controller and the second panel.
3. Armrest controller failure.
Solution:
The remote set switch is mounted on the second panel and wired to the armrest controller. The switch position
information is broadcast over the Data Bus and can be monitored in the monitor screen of the service tool.
The remote set switch is built in as an integrated part with the second panel. If it fails, the whole second panel must
be replaced.
The remote set switch with the power supply and ground is connected to the armrest controller through connector
J2.
Always check the connection between the second panel and the armrest controller first. Make sure there is no
damaged wires, loose connections, or bent pins.
It is hard, but possible to test the remote set switch and the wiring circuit.
1. Open the armrest controller housing and disconnect connector J2 of the second panel from the armrest
controller.
2. Check the remote set switch function:
a. When the switch is in EXTEND LIMIT SET position, there should be continuity between pin 11 and pin 14
and no continuity between pin 12 and pin 14.
b. When the switch is in RETRACT LIMIT SET position, there should be continuity between pin 12 and pin 14
and no continuity between pin 11 and pin 14.
c. When the switch is in OFF position, there should be no continuity between any two of pin 11, pin 12 and pin
14.
If the switch is not functioning as specified above, replace the second panel (panel with hitch or panel without
hitch).
3. Check controller function:
a. Turn tractor key switch to the ACC position.
b. Check the power supply from the armrest controller at pin 14 of J2. It should be approximately 12 volts.
c. Short wire pin 11 to pin 14 to simulate the EXTEND LIMIT SET function. Short wire pin 12 to pin 14 to
simulate the RETRACT LIMIT SET function.
Monitor the switch status on the monitor screen of the service tool.
If the controller does not function properly, replace the armrest controller.
4. If none of above, clean the connectors and reconnect the second panel to the armrest controller.
Calibrate the armrest controller and check for fault codes again.
If no fault code is recorded, the fault is fixed.
If the fault code is recorded again, replace the armrest controller.
When the switch is in OFF position, there should be no continuity between J2-11, J2-12 and J2-14.
If the switch does not function as specified, replace the switch.
NOTE: See schematic sections 47 and 48 on schematic poster.
