TROUBLESHOOTING
DIAGNOSTIC TIPS
Check the fault codes using the BRP diagnostic software (BUDS2) as a first troubleshooting step.
Make sure the m
odules are powered before testing CAN.
CAN Communication Problems
The followin
g chart gives some symptoms and behaviors relative to the CAN component in cause. The
list is not ex
haustive, only the most significant items are given to help in troubleshooting.

any electronic module.
"No vehicle detected" message
will be displayed in BUDS2.
Information center
(gauge)
Check engine light is ON.
iBR light is ON.
Some functions not displayed such
as: Engine hours, VTS and RPM.
2 modules instead of 3 will be active.
"Cluster" tab and its data will
not be available in BUDS2
ECM and iBR will report a cluster CAN
problem.
ECM (Engine Control
Module)
Engine is set to limp home mode.
Check engine light is ON.
iBR light is ON.
iBR gate w ill return to VTS position.
Some functions not displayed such as: Engine
hours and RPM.
2 modules instead of 3 will be active.
ECM tab and its data will
not be available in BUDS2
iBR will report an ECM CAN problem.
iBR (intelligent Brake
and Reverse )
Engine is set to limp home mode.
iBR gate w ill return to VTS position.
iBR light is ON.
Check engine light is ON.
Some functions not displayed such as: Lake
water temperature, no VTS, no F, N and R
indication.
2 modules instead of 3 will be active.
iBR tab and its data will
not be available in BUDS2
ECM will report an iBR CAN problem.
Depth sounder
The menu Depth Sounder
Indicator will not be visible.
The D epth menu will not be available.
Nothing will be observable.
Diagnostic connector Nothing will be observable.
BUDS2 will not be able
to communicate with
any electronic module.
"No vehicle detected" message
will be displayed in BUDS2.
If the gauge cannot communicate with an optional accessory (e.g.: depth sounder) during the initial power
up, the gauge will interpret this a s if the vehicle is not equipped with it. No further test of the system
occurs and no indication or fault message will be visible. If communication is interrupted after the gauge
has already detected them, then the gauge will indicate that there is a communication fault.
