What should I do if my brake controller is not working?
If you have a time-delay brake controller and there is no power on the blue wire with the brake pedal pressed, check the connection of the red (stop light switch) wire from the brake controller. This wire should be connected to the wire from the brake light switch that only has power when the brake pedal is pressed.
What causes trailer not connected message on Ford F150?
If this message is observed without a trailer connected, the concern is with the vehicle wiring from the TBC module to the 7-pin trailer connector. TBC FAULT — This message is displayed if the Instrument Panel Cluster (IPC) is receiving communications from the TBC module, but has not been configured for a trailer brake system.
How many wires does a trailer brake controller have?
Most brake controllers have 4 wires, blue (brake output to trailer brakes), white (ground), black (12 Volt power from vehicle battery), and red (stop light switch). If your brake controller is not on, make sure the black power wire is connected to the vehicle battery via a 20 or 30 amp circuit breaker.
What does it mean when your trailer is not connected?
WIRING FAULT ON TRAILER — This message is displayed when the trailer brake output circuit is shorted to ground or shorted to voltage. A DTC sets in the TBC module indicating which circuit fault was observed. It is important to determine if a trailer was connected when this message was displayed.
If this message is observed without a trailer connected, the concern is with the vehicle wiring from the TBC module to the 7-pin trailer connector. TBC FAULT — This message is displayed if the Instrument Panel Cluster (IPC) is receiving communications from the TBC module, but has not been configured for a trailer brake system.
How does the trailer brake module work on a Ford PowerStroke?
Every 4 seconds (when not braking) the TBC module sends a voltage pulse to pin 3 of the 7-pin trailer tow connector to determine whether or not a trailer is connected. DTC C2806 (Trailer Brake Output Circuit Short to Vbatt) – sets when the TBC module detects that the battery voltage is greater than 9 volts while not braking.
Why is my 7 way trailer not connected?
It can sense when a trailer is connected based on the voltage draw so it won’t sent a signal for 12V when using some testers, especially LED testers because there isn’t enough of a power draw. The system requires a power draw on the 7-way and then holding the brake pedal for about 3 seconds until your dash registers “trailer connected”.
What should I do about my trailer brake controller?
Just for giggles, unplug the harness from the back of the bumper plug socket and inspect. Also, follow that wiring forward to at least the fuel tank to look for integrity, or previous owner patches in the wiring. Click to expand… Showed 13V from F on the harness grounded to chassis.
