Functional Test Procedure

Testing the DSC for Correct Wiring

Before proceeding with the following test procedure,
it is important to have the DSC unit powered on with
a green status light. Failure to power the DSC before
proceeding may result in a permanent failure or
malfunction of the unit.
In order to verify that the DSC is wired correctly, follow the test
process listed below:
1. Ensure that the trailer battery is fully charged or that a
charging device is connected to the trailer.
2. Connect the +12V to the black wire on the DSC and ground
the white wire from the DSC.
3. Connect a brake controller to the brake signal (blue) wire of
the trailer harness.
4. Turn on the brake controller and apply the manual override
until the DSC status light comes on.
5. Verify that the light is GREEN and that it is "flickering". This
indicates no faults with the DSC. If the light is not GREEN,
refer to the troubleshooting section to correct the detected
fault(s).
6 Refer to Figure 1 and Figure 2 on the following page to
verify correct wiring on the left and right sides of the trailer.
After the trailer passes the left side test, reconnect the left
side brake as normal before repeating for the right side test.
Note: It is very important for the wire test connection to
be made back near the left and right side trailer brakes.
Do not perform this test up front near the DSC since
that will not verify correct wiring back at the brakes.
7. If the DSC status light does not flash the correct number of
times as indicated in Figures 1 and 2, make the necessary
wiring changes so that the flashes match the correct side.
