7.2.3
Troubleshooting
Problem

LED is off.
The system status LED
is flashing yellow.
The system status LED
is flashing red. Both
tab position indicators
are solid.
EN
Cause
The ignition is not
on.
Circuit breaker or
fuse has tripped.
The controller is not
receiving a wakeup
signal.
If one or both tab
position indicators
are off, the tab(s)
have failed to home
correctly.
Battery voltage is
too low or too high.
Remedy
Turn on the ignition.
Reset breaker or replace fuse.
Optimus Adaptive Trim Tab System:
if the CANtrak is on, check the
connections in the CAN2 network.
If the CANtrak is not on, check the
Optimus EPS ignition sensing wire.
Adaptive trim tab system: check
the ignition sensing wire.
Try pressing the Home button again.
Check that nothing is physically
preventing the tabs from moving to
the home position.
Switch off power and swap the
connectors between the two
actuators. Turn the power back on
and try homing again. If the actuator
still does not home correctly it will
need to be replaced. If it does
home correctly, then there is a
problem in the communication or
power harness.
Check battery voltage.
