Labrie does not archive previous revisions of programs; this will ensure if there is any issue with
the new program the original may be installed back into the module. Failing to upload the original
program will result in it being lost when the revised program is installed.
• Connect a PC with the CoDeSys program installed, to the Labrie control console.
• Turn the vehicle ignition to the on/run position
• Open the IFM Download program on the PC.
• Select the Identity tab to ensure that the PC is communicating with the Labrie IFM system.
• Select the Upload tab. A prompt will appear to name the program; typically, the original
program and revision number is used.
• Save the program on the PC (This will take several minutes).
• Once the IFM program uploads an “UPLOAD COMPLETE” message will appear; select “OK”.
After completing these steps, the new program may be downloaded. After download is complete,
check to ensure that the baud rate setting matches the original setting noted earlier to avoid chassis/
Labrie system communication issues.
Once the updated program is loaded and verified to be working correctly the original uploaded file
should be deleted from the PC to avoid future confusion.
Checking Control Module (Node) Supply Voltage
A benefit to the IFM multiplex control systems used on MINIMAX™ products 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:
