2 INSTALLATION
2.4 Active Calibration
When the unit is first powered, Active Calibration must first become confident in
the vehicle direction of travel. Until this time the LED will flash Blue/Green.
Time Time
During Calibration: Once Calibrated:
Active Calibration constantly monitors the vehicle’s direction of travel and allows the
Tow-Pro™ Elite to ‘learn’ and continuously confirm its mounting orientation. This process
occurs whilst the vehicle is moving and the brake is applied and will occur with or without
a trailer connected.
When the Tow-Pro™ Elite is first installed it will begin learning its mounting orientation
through Active Calibration as soon as you start driving, at this point Proportional Mode is
selected but not yet fully operational.
Until the Tow-Pro™ Elite has determined its mounting orientation the unit will function as
if in User-Controlled mode, this is indicated by the LED glowing green with blue flashes.
As the Tow-Pro™ Elite becomes more confident of its direction of travel the length of the
Blue flash will increase, to the point that the LED is solid Blue which indicates it is now
operating completely in Proportional mode.
Under normal driving conditions the Tow-Pro™ Elite will learn its mounting orientation
within 20 brake applications. Note that the braking must be perceptible (applying the
brake while stopped will not assist calibration).
If power is disconnected (for example, if the vehicle battery is changed) calibration
memory will be lost and the unit will recalibrate itself using active calibration. This is
similar to a radio losing its clock or preset station memory.
If no trailer is connected, Active Calibration will occur as normal without any indication
from the LED. The LED will already be Blue when the trailer is connected. Essentially,
whether a trailer is connected or not, just drive normally and Active Calibration will ensure
the Tow-Pro™ Elite learns the correct direction of travel.
