Another self level inactive question
 

I have a 04 4.8is with this famous sel level inactive on the dash. I have checked the 30 amp fuse and it was fine and I replaced it anyway also I replaced the relay.
So my truck is level no air leaks but the compressor has not come on in 2 weeks and it is starting to look like its getting lower in the back after 2 weeks. Can I actuate the relay to fill the airbags up to buy more time to troubleshoot. What is the best way to tested the level sensors. I dont have any water or any signs of moisture in the battery compartment and everything looks brand new like the compressor and control module.
Thanks
Craig

Ur control module is behind glovebox

My front bags leak a little bit, compressor kiks in 1 time in a month and my sls light is on

I thought the control module was right beside the battery ?

It depends on how your X is optioned. If you have the rear "single axle" (EHC I) suspension...then it is near the battery. If you have the "dual axle" (EHC II) suspension...then it is up front behind the glove box.

Which system do you have?

He has a 4.8is it only came with 2axle front n back air springs/bags

I have the dual axle so I will check out my connections behind the glove box today. Is there anyway to bypass the controller and run the compressor to fill the system up. maybe by the relay to the compressor. Also, what is the best way to test the level sensors to find out which one is bad.
Thanks again
Craig

Help us help you better by creating a signature that includes your model/model year/build date (or add it to the info that appears in the upper right). :)

There are multiple models, engines, transmissions, & other changes that occurred during the production run from the 2000-2006 model years that helps us respond with better answers (correct ones etc) as well as if we need to look up info/diagrams/part nbrs etc....which all require info/details. By not having this info, your posts may either get ignored, skipped over, or may take longer by having to ask for the info needed to respond...which again, can add time to getting the info you needed.

Sorry about that I thought I had that in there must have been E46 fanatics.

I believe you normally check the sensor(s) voltage.

If you have access to a GT1, here are diagnostic steps on SLS Inactive:

If you have a leak (my guess), don't put off repairs too long or you will need to replace your compressor too.
