Section 06 STEERING AND PROPULSION
Subsection 02 (iBR AND VTS)
If battery voltage is not measured, check the fol-
lowing:
– 30 A iBR fuse in FB2
– Battery voltage at fuse contact D11 of FB2
– Wire continuity pin 2 iBR 3 pin connector to D12
of FB2
– Jumper continuity fuse contact FB2-D11 to
FB2-A6 of 12 Vdc bus-bar.
If voltage is good to the negative battery post but
not to pin 1 of the connector (ground wire to en-
gine), check for an open or bad ground wire (loose,
corroded, or pitted terminals, wire continuity, etc.)
If battery voltage measured is as specified, carry
out same test using a 12 Vdc test light. Test light
should be bright.
If test light is not bright to pin 1 only, look for a
bad contact on the ground circuit (loose, corroded,
pitted, etc.).
If test light is not bright to the negative battery
post, first check voltage at battery terminals to
ensure battery is not discharged. If battery volt-
age is good, look for a bad contact in the 12V iBR
unswitched power circuit (loose, corroded, pitted,
etc.).
If un-switched 12 Vdc power to the iBR actuator
is good, test for the switched 12 Vdc as per fol-
lowing steps.
4. Briefly press the START/STOP button to wake
the electrical system.

Step 1: Press START/STOP button
Step 2: Install D.E.S.S. key
5. Measure for the switched input voltage to the
iBR actuator as per following table.

NOTE: The 5 A switched power to the iBR actua-
tor is for the iBR electronic module and BRLS.
If battery voltage is not measured at all, check the
following:
– 5 A iBR control (CRTL) fuse in FB1
– Battery voltage at fuse contact A4 of FB1
– Wire continuity pin 1 iBR 12 pin connector to A3
of FB1
– Jumper continuity fuse contact FB1-A4 to
FB1-C2 of 12 Vdc accessory bus-bar.
If voltage is good to the negative battery post
but not to pin 1 of the connector (ground wire to
engine), check for an open or bad ground wire
(loose, corroded, or pitted terminals, wire conti-
nuity, etc.).
If battery voltage measured is as specified, carry
out same test using a 12 Vdc test light. Test light
should be bright.
If test light is not bright to pin 1 of the 3 pin con-
nector, look for a bad contact on the ground circuit
(loose, corroded, pitted, etc.).
If test light is not bright to battery negative ter-
minal, first check voltage at battery terminals to
ensure battery is not discharged. If battery volt-
age is good, look for a bad contact in the 12 V
iBR switched power circuit (loose, corroded, pit-
ted, etc.).
If the iBR actuator input voltages and ground cir-
cuit are good, and there is no CAN bus or BRLS
fault, replace the iBR actuator.
iBR Actuator Removal
1. Move the iBR gate to the forward position (full
up) using the iBR OVERRIDE function. Refer
to SYSTEM DESCRIPTION (iBR) in this subsec-
tion.
NOTICE
Do not try to move the iBR gate by
hand with the locking sleeve (iBR key) installed
or component damage will occur.
CAUTION Wait at least 5 minutes for wa-
tercraft electrical power system to shut down
before working in the iBR gate area.
