Replacing the CAN Bus-Based Multiplexed System Joystick
Should the CAN bus-based multiplexed system joystick need to be replaced for any reason, it will
have to be replaced with a new joystick with the same part number in order to insure continued
proper operation of the multiplexed 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 Labrie

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 multiplexed system monitors all safety and operating functions to insure they work at their
best. This system transfers data to and from Allison transmission ECU and Cummins engine ECM.
In order for this to be possible, proper parameters must be put into these ECU and ECM. In the next
section you will find tables that contain such parameters.
Allison Transmission Parameters
In Allison transmissions used on automated vehicles, the electronic control unit (ECU) manages
several functions:
It prevents the pump from overspeeding (2,000
rpm,
maximum).
It prevents the pump from engaging if the engine speed is higher than 900
rpm.
It shuts off the arm joystick if the vehicle is moving faster than 2
mph
(3.2
km/h).
It also controls the auto-neutral system (if present).
The ECU is programmed using the Allison Doc software installed on a laptop computer. Allison Doc
is also necessary to verify if signals are properly reaching the ECU, and to verify the fault code.
