Chapter 5: Maintaining and Servicing the INTEGRITY

Integrity Lightbar
Removing a PCB
To remove a PCB:
1
. Disconnect all power to the lightbar.
2.
Use a T27 Torx driver to remove the 1/4"-20 Torx-head barrel nuts securing the lens (Figure 5.2 on
page 38). Carefully remove the lens and cover as a unit. Avoid damaging the lip seal.
3.
Verify that an O-ring is under the head of each barrel nut and not stuck to the lens. Use a wooden or
plastic pick to carefully remove the O-rings from the lens to prevent damaging them.
4.
Inspect the O-rings and the lip seal for deformation, brittleness, cuts, or tears. To maintain
watertightness, replace a questionable O-ring or seal.
5.
Note and record the connection to the PCB, then lift it and disconnect the harnesses.
6.
Remove the PCB from the lightbar.
Reinstalling a ROC PCB
To reinstall a PCB:
1.
Place the new PCB in the same position as the old PCB and reconnect the harnesses.
2.
Reinstall the lens with the cover. To prevent cross-threading the barrel nuts, back them counter-
clockwise until you hear the click of the threads engaging, then tighten them to 16-24 in-lb in the
sequence shown in Figure 5.2 on page 38.
3.
Reconnect power to the lightbar.
Resetting the Controller
These instructions explain how to reset the Valor lightbar controller after you install a service replacement
board or if the lightheads operate erratically. For the Valor lightbar to operate correctly, the controller stores
information about which LED colors it controls. Resetting the lightbar controller may be necessary if you
replace the controller board or if the LEDs flash erratically. To scan which colors are available at the end of
the reset cycle, the controller briefly flashes all LEDs simultaneously.
Be sure to perform the reset cycle on a vehicle with a well-charged battery. Failure to do so may cause the
lightbar to flash or operate incorrectly.
To reset the controller:
1.
Remove the barrel nuts and lens from the lightbar. (See Removing and Reinstalling the Lightbar Lens on
page 37).
NOTE:
If you are replacing the controller, ensure that power to the lightbar is off, then disconnect all
connectors to the controller. Install the new controller and re-connect all cables to the controller board.
2.
Connecting the main power and ground wires from the lightbar to the battery.
3.
Apply ignition power to lightbar control head. Verify that the “POWER ON” LED is lit on the Valor
controller board.
