Replacing the CAN Bus-Based Multiplex Joystick
Should the CAN bus-based multiplex joystick need to be replaced for any reason, it will have to be
replaced with a new joystick of the same kind and same part number in order to insure continued
proper operation of the multiplex system. Do not use other kind of joysticks even if they bear
similarities to the CAN bus-based joystick. For more information on CAN bus-based joystick
replacement, contact LabriePlus.

NOTE: The PTO can only be turned on when the engine speed is lower than 900 RPM and the air
pressure higher than 90 PSI. It is recommended to raise the engine speed only after the
hydraulic system is engaged.
Labrie’s multiplex system monitors all safety and operating functions to insure they work at their best.
This system transfers data to and from the Allison TCM and the Cummins engine ECU. In order for
this to be possible, proper parameters must be put into the TCM and the ECU. In the next section
you will find tables that contain such parameters.
