
If both light and board power up then connect all wires back to the circuit board and verify that
system powers up and blinks three times on a power up event both on the circuit board and at the
front light on the trailer.
If the lights on the circuit board blink but the light on the trailer does not then you have a
circuit board problem.

If both the light on the trailer and the light on the board blink 3 times next check that the blinking
stops or that the light on the front of the trailer goes to a solid on state or consistent blink state or
an off state. Those are all three valid states.
If the light on the trailer keeps blinking but in an inconsistent manner like two fast then one
slow this means that pressure has not reached the control box yet. Check that the air control
valve is in the on position.
If the control valve is in the on position then the brake system has not received enough air to
open the PPV valve yet. Wait for the airbrake tank to fill or check glad hands are connected to
the tractor.

If the light stays on solid or blinks consistently in timing then the system is taking air. If no hissing is
heard coming out of the air connections then the tires are low and simply taking air.
If hissing is coming from an air connection, fix the leak.

If the light goes out after the first 3 blinks then all is ok and tires are aired up.
