The Ford TBC has only been verified to be compatible with
trailers having electric-actuated drum brakes (one to four axles)
and not hydraulic surge or electric-over-hydraulic types. It is the
responsibility of the customer to ensure that the trailer brakes are
adjusted appropriately, functioning normally and all electric
connections are properly made.
The TBC user interface consists of
the following:
1.+/- (GAIN adjustment
buttons):Pressing these buttons
will adjust the TBC’s power output
to the trailer brakes (in 0.5
increments). The GAIN setting can
be increased to a maximum of 10.0
or decreased to a minimum of 0 (no
trailer braking). Pressing and
holding a button will raise or lower the setting continuously.
2.Trailer connection indicator:This lamp indicates trailer electrical
connection status.
•When a successful trailer connection is detected, the indicator will be
green.
•If the electrical connection is lost, the indicator will flash red. If the
connection is lost while the vehicle is stationary, the indicator will turn
off after 30 seconds. If the connection is lost while the vehicle is
moving, the indicator will flash until the ignition is turned off, then on
again or if there is a reconnection.
•If no electrical connection is detected after the ignition is turned on,
pressing a GAIN adjustment button will display the GAIN setting.
Sliding the manual control will display the GAIN setting, OUTPUT bar
graph and light the trailer indicator red.
3.GAIN setting display:Shows the current GAIN setting. This will
illuminate when a trailer is connected, flash if the trailer becomes
disconnected, or remain off if no trailer is connected.
4.OUTPUT bar graph:When the vehicle’s brake pedal is pushed, or
when the manual control is activated, green bar indicators will illuminate
to indicate the amount of power going to the trailer brakes relative to
the brake pedal or manual control input.

5.Manual control lever:Slide the control lever to the left to activate
power to the trailer’s electric brakes independent of the tow vehicle’s
brakes (see the followingProcedure for adjusting GAINsection for
instructions on proper use of this feature). If the manual control is
activated while the brake is also applied, the greater of the two inputs
determines the power sent to the trailer brakes.
•Stop Lamps:Activating the TBC manual control lever will illuminate
both the trailer brake lamps and the tow vehicle brake lamps except
the Center High-Mount Stop Lamp (presuming proper trailer electrical
connection). Pressing the vehicle brake pedal will also illuminate both
trailer and vehicle brake lamps.
GAIN:
The GAIN setting is used to set the TBC for the specific towing
condition and should be changed as towing conditions change. Changes
to towing conditions include trailer load, vehicle load, road conditions
and weather.
The GAIN should be set to provide the maximum trailer braking
assistance while ensuring the trailer wheels do not lock when braking.
Locked trailer wheels may lead to trailer instability.
Procedure for adjusting GAIN:
Note:This should only be performed in a traffic free environment at
speeds of approximately 20–25 mph (30–40 km/h).
1. Make sure the trailer brakes are in good working condition,
functioning normally, and properly adjusted. See your trailer dealer if
necessary.
2. Hook-up the trailer and make the electrical connections according to
the trailer manufacturer’s instructions.
3. When a trailer with electric brakes is plugged in, the trailer connection
indicator will illuminate green on the TBC and the GAIN setting display
will illuminate.
4. Use the GAIN adjustment (+/-) buttons to increase or decrease the
GAIN setting to the desired starting point. (A GAIN setting of 6.0 is a
good starting point for heavier loads.)
5. In a traffic-free environment, tow the trailer on a dry, level surface at
a speed of 20–25 mph (30–40 km/h) and squeeze the manual control
lever completely.
