Right forgot. If Depo's or DLA buy the kits I am sure they issue a number but it is too early yet.

This is a good question. The selling entity would need to have an account set up with Dana Crossville Aftermarket the same as a truck parts distributer. I do know that every hand that touches a part increases the cost so maybe someone on this site has access to an account.

No they do not sell separate sub-components What is an NSN?

There is now a CTIS Wheel valve rebuild kit that will be sold through Dana Aftermarket but they will need to see orders before they will build and stock them. Unfortunately I do not have the SRP yet. The kit includes a new diaphragm that will not fail in the cold or cause corrosion. It also...

The kit is now in the Dana Aftermarket system but they will need to see orders before they will build and stock them. Unfortunately I do not have the SRP yet. The kit includes a new diaphragm that will not fail in the cold or cause corrosion. This includes a vented cover and protective bracket...

Yes it started on the A1P2

They are threaded. I did not want to include the seat as the kit without the seat would service 10 or so part number wheel valves, with the seat it would only be specific to one or two valves. I can check about making the seat available for LMTV/FMTV

Hello Everyone, I have run into a holdup on the updated wheel valve release so I am perusing a rebuild kit instead. This kit would include a vented cover and protective bracket, new diaphragm good for -30F operation, and screws. The seat and spring would be your responsibility to clean and...

Please keep in mind that software configurations set by the ECU pins M and Z also set fault tolerances for a specific chassis. Selecting an incorrect config could cause pressure reading to be inaccurate, over inflations, or even a flashing light fault to occur. S&S and later models are all wired...

AXTS0015 Troubleshooting Guide

You can disable the ECU by interrupting the PS Pressure Switch signal or put a 5 amp switch in line with the 24v power wire. The ECU had protections against power surges and very robust. Welding on the chassis with the vehicle power on can cause issues but not jump starting.

The only light for CTIS on the dash is the overspeed warning light. It should flash if the truck speed is exceeding the limit for the tire pressures and be on solid if the speed signal is no longer present after 50 key cycles. It will turn off as soon as the ECU sees a speed signal. Attaching a...

Most Trucks that have a CTIS disable switch for an arctic kit use the pressure switch wire. This way is can be disabled before start up and easily engaged after running down the road and the seals are warmed up. Take either with at the the switch, cut and splice two wires, then run them up to a...

Old wheel valves can be a problem and they will perform worse when it is colder out. Just take it apart and clean everything good. Remove any corrosion from the stainless seat and use a lightweight oil to soften the rubber diaphragm.

The PCU will handle 140 PSI so it is not a problem. When using switched you have inflating is easy, just turn on "Control" then "Supply" and air will flow into the tires if the supply is higher than the tires. NOTE* If the supply is lower than the tires, the tires will deflate down to the...

You do not need the ECU to control the system. There is a switch box diagram on one of the other posts. The PCU has the deflation relief valve that controls the line pressure at 8psi allowing the wheel valves to dump. You also do not want to turn on "supply" without turning on the "control"...

Sounds like the switch is bad. You could take the metal bezel off and use a razor knife to cut around 3 sides of the button then peel the cover back and see if you can clean the contacts. The metal dome will come out and you could use a metal clip to short the contact and make sure they work. If...

Great to hear, we hope to have some better wheel valve parts coming soon that will solve the old cold temperature issues.

Some green modules after 1998 can communicate with the tool on a J1587 link. All black modules should be able to use a CAN link.
