3.5 LED Indication
The Tow-Pro
™
Classic will indicate both Mode and Fault Condition through colour and
fl ash sequences of the LED indicator. The table below shows how the Tow-Pro
™
Classic
will indicate Normal Operation of the unit.
NOTE: LEDs will glow full brightness when gain control is adjusted or manual
override is pressed. After release of the gain control knob the LED brightness
will reduce. This is designed to be less intrusive on driver’s vision at night.

1 Sleep Mode occurs when there is no trailer connected to the vehicle.
2 Breathing, as opposed to fl ashing, is the LED gradually getting brighter until its
brightest point and then gradually dimming until off.
3 The LED will vary between Green and Red depending on the braking force.
3.6 Troubleshooting
The Tow-Pro
™
Classic features sophisticated diagnostics to warn the operator of faults
in the vehicle and trailer brake wiring. Wiring faults are indicated by a series of colour
coded fl ash patterns on the Tow-Pro
™
Classic LED. Even intermittent faults are detected
and may be indicated until cleared. The warning code can be cleared by unplugging the
trailer for 1 minute then reconnecting. A fault indication should not be ignored though,
as it is a warning & if left unattended, such wiring faults can become worse and may
lead to deterioration or loss of trailer braking.
Please refer to the table on pages 14 & 15 for the list of fl ash patterns, showing the
cause & recommended course of action for each of the conditions that may be detected.
