if you are programming the controller settings in the traction controllers both of them have to be set to the same identical settings (except for function 15 and 17).
here are the ones i show for this truck model with the SR/SP traction controller (standard settings).
-Columns- -First number is function number, second is function description, third is minimum suggested setting number for left and right controllers, fourth is factory default settings, (note: those that have different numbers ie:81/121), are a range that can be set on both controllers because remember, both have to be set identical unless it specifies differently),fifth is max settings.

NOTE: Left and right controller functions must be programmed to identical values, except for Function 15 and
Function 17.

There are 3 ways you can program these:
1-use the Yale Software and plug in to the DB9 connector behind the display
2-use the GE Handset and plug straight into the controller
3-use GE Sentry on a laptop w/correct cable and usb adapter and plug straight into the controller. (left is primary, right is secondary/slave).
Primary first, then secondary.
If you do it in the wrong order the settings will not save and revert back to previous ones.
ALWAYS recheck your settings after completing to insure they take, and are saved into controller memory.
When completing programming, shut off machine, press horn button to drain power from system, then power back on and recheck settings.
