Warfighters, the semiannual PMCS instructions for inspecting the FMTV’s central tire inflation system (CTIS) wheel valve assembly have been updated.

Here’s how to properly inspect the CTIS on all FMTV wheel and tire assemblies:
  1. Start the truck and allow CTIS to build up air in the tires until the flashing light on the selector turns solid red.
  2. After CTIS has completed the inflation cycle, turn the vehicle’s engine switch to the OFF position.
  3. Spray the CTIS valve assembly, control hose assembly (large hose) and tire hose assembly (small hose) with water mixed with liquid soap to check for leaks. Where bubbles start to form, there’s likely a leak. If leaking, repair or replace the leaking part.
