Air bags to coils and keeping a battery for the night.

I swapped my D2 from airbags to coils today and pulled the fuse under the hood for the sls. While driving a few miles, I noticed the light for sls never came on. However, when parked the truck, I noticed a clicking noise from where the compressor is. I pulled the 2 plugs from the compressor and started the truck up. Now the light is on. No clicking. Have I properly shut off the system for the day so it won't kill my battery trying to deflate bags that don't exist? I will have a shop set the computer to coils monday, but don't want to have my battery go flat overnight.

Looks like the battery is unaffected from sitting overnight. I drove the truck after unhooking the compressor connectors and height sensors last night, then drove a couple miles. The sls alarm was chiming constantly when the truck reached 20+ m.p.h. This morning, the light is till on, but no chime. Onward.

The best solution is to use an appropriate computer to change the setting in the SLABS from air to coil. That disables all the sensors, chimes, etc.

I did the same conversion back in 2004...it will kill the battery eventually if you don't start it up every day or two. Reprogramming the SLABS fixed it for me.

I got it all sorted. Took the truck in to a shop with the expensive computer to program it to coils. They also programmed my key fob. For the first time in my life, I own a vehicle with keyless entry (that works, anyway).
