Disabling Rear SLS
 

Hello everyone. I finally have time to work on the D2 again so I am tackling something I have wanted in a 4WD for a long time. I am installing an air compressor and tank from Viair. My D2 has a 2" lift and had rear SLS so no more air bags. However, everything else is still there (height sensors, air lines, air compressor). I want to put in my new air compressor where the SLS one lives right now, but I removed it and now there is an air suspension fault (obviously). I could live with the light on the dash, but it constantly beeps when you go over 20mph.

Any way that I can disable this? Maybe clip specific wires for SLS going to the SLABS or do I have to get it reprogrammed? Could I replace the SLABS with one from a non SLS truck and have it work? Would be a good excuse to get an 04 SLABS as I have added a CDL.

If none of those would work, I do have to get it reprogrammed right?

Thanks in advance.

Edit: I also think that the air compressor might be killing my batteries. Truck had a year old battery when I bought it and PO said it was on its way out. I replaced it because it died a week later and now that battery died two weeks ago.

The SLABS needs to be reprogrammed when you switch to coils. That will get rid of the errors and then you can just unplug/remove everything.

X1 .............. yep.

Looks like a pretty definitive answer. Alright then, I'll take it to my indy mechanic for reprogramming. Thanks everyone

Reprograming or another SLABS with SLS disabled. Then remove the SLS relay.
