Electrical System 319
If the engine RPM value on the Labrie system is not changing and synchronized with the chassis
tachometer, the baud rate most likely needs to be reset to 500 Kbps. Effective early 2016, The Labrie
system has been modified to allow changes to this value. Using the directional pad, select the
SETTINGS option in the main menu and press OK. Then, highlight the J1939 BAUDRATE and
press OK.
The baud rate may be changed by depressing either the left or right arrow on the directional pad, to
select 500 Kbps. After any modification to the baud rate, the ignition switch must be turned off for at
least 10 seconds to reset the system. Go back into the Settings option and verify the baud rate value.
Ensure that the Labrie system and the chassis system are communicating correctly by checking the
engine RPM as explained earlier.
Checking Control Module (Node) Supply Voltage
A benefit to the IFM multiplex control systems used on EXPERT™ units is the ability to verify inputs
and outputs through the display screen quickly, without the need to connect a diagnostic reader or
laptop PC. However, prior to checking the status of these outputs, the supply power voltage for each
control module (Node) must be checked to ensure that it is at least 12 volts.
Effective on production models manufactured in early 2017, the diagnostic features of the IFM
multiplex control system have been further enhanced; supply voltages for the control modules
(Nodes) may now be checked through the on-board display, as follows:
