Demco SBS Air Force One Replacement Parts for Poor Vacuum on 2018 Jeep JK Rubicon  

Question:

My Jeep Wrangler Rubicon is a 2018 jk model. It gives me traction control warning light about 50 per cent of the time I drive it The local Jeep dealer found the diagnostic fault analysis to indicate low vacuum pump data. They believe that that was a leak in the Air Force One control box. They disconnected the vacuum line and capped the tee in the Jeep vacuum line. Is there any more checks of the AF1 control box that I can perform? Can you supply a replacement if needed?

Expert Reply:

The Demco SBS Air Pressure Stop Light Switch Kit for Towed Vehicles - Air Force One # SM99629 will have that fitting you are referencing. You will also want to check any fittings like the Replacement 1/4" Female Pushlock Fitting for Demco SBS Supplemental Braking Systems - Qty 1 # SM99611 or check valves # SM99909.

If the controller is the issue then you will need the Demco SBS Second Vehicle Kit for Air Force One Supplemental Braking System # SM99209. The controller is not available separately.
