  1. Unknown #10 Dave & Wendy Schonhardt in front of a rental motor home.
  2. https://www.scangauge.com/products/scangauge-d/ Reads most codes and can also be customized. This is what the plug looks like on a Volvo. Plug is located facing downward on the lower left side dash panel adjacent to the hood release handle. This is referred to a 9 pin deutsch connector. It is the test plug for both the J1939 and J1708 network protocols used. This is what is used on most HDT's in place of OBD II.

    AIR LEAKS-I give up!

    Look at the check valves on your front and rear tanks. Sometimes shaving cream in place of soapy water will “show” smaller leaks. Lots of valves will leak internally and make it hard to find. Cummins ISX check the turbo actuator control valve... sliver box, drivers side below the air compressor. Follow braided line over to turbo and check for leaks. Engine fan hub and associated lines and connections. Parking brake valves and lines are bad apples for leaking. Above the air tanks located on the inboard side of the frame rail is a “brake control valve”. Looks like a junction box of lines. Gen 1 Volvo’s have 6 lines going in and out and Gen 2 have 8. Leaks internally all the time. Some airtank fittings have a protective boot to keep out crud. These sometimes will mask a leak. Sometimes you need to “wiggle” the air lines a bit to hear the leaks. Temperature changes will also reveal new leaks. If you do find a PTC fitting leaking you can usually repair it by replacing the o-ring inside instead of buying a new fitting. As mentioned air bags and leveling valves can leak and drive you crazy! You can inflate your bags to “reveal” the bottom edge and check for weather cracking. Lots of bags look ok but need replacing. If you can “isolate” your front and rear tanks you can get a better picture of what may be causing your leaks. Front system includes a lot of your accessories, such as seats. Rear is mainly rear brake system and such. Do you have an air ride hitch? Check it out. Just thinking out load....
  4. Gen 2 Truck. Did not remove door panel. Switch panel just snaps into its mounting cavity. I just gently pried it out from the top starting at the end closest to the door opening lever.
  5. The switch panel mounted on the drivers door is the “controller” for the power windows, power door locks, and the power mirrors. It is easy to change out. It just “snaps” out from the top of the door panel. Pop it out and get the part number off of it and order a replacement. It’s an easy part to get on-line I replaced one for a passenger window that stopped working.
  6. Something else that works out pretty good for those of us that have our HDT equipped as an RV is the ability to just use just the HDT for shorter trips. Our family uses our HDT “ camper” lots of weekends chasing my son’s travel baseball team around the Southwest. The HDT makes the longer drives more pleasurable and we can camp out at Wally World while enjoying some fine baseball!

    Air dryer

    What model of air dryer do you have? Filter price seems in the ball park. Complete assembly price seems like a steal!
  8. You can use either one. I believe Lippert recommends no more than two quarts of the CAT additive.
