Default No Voltage to SLS copressor, SLS light on, No code

What am I missing here guys. First time I have dove off into an SLS and could really use some help.

Removed the rear coils and put back to SLS with new bags. Everything else was there. Compressor, ride height sensors, hoses, etc. Just needed bags.

Turned on Key...Nothing

Pulled plug at compressor and have no voltage going to it.

Relay-Good
Fuse under hood-Good

Nanocom States this:
Left Sensor Value: 121
Right Sensor Value: 116
Left Sensor Supply: 4.95
Right Sensor Supply: 4.92
Left Valve: 0.0
Right Valve 0.0
Exhaust Valve 0.0
Compressor Relay .20 and it toggles between .13/.20/,27

I can activate the compresssor with the nanocom so I know it works

When i switch from the coils to air on the nanocom and hit write settings turn it off and then turn it back on it shows coils again. What am I doing wrong?

Need some help now

You have to change a setting using your Nanocom to tell the vehicle that it has bags instead of coils.

From memory, I think there may be a couple of fuses for the SLS. Maybe one in the fusebox under the dash? Check the D2 electrical library for a full description of the circuit paths and which relays/fuses are involved.

Thanks Mollusc, I will check that.

I was able to activate the compressor with the nanocom so I know it is good.

Problem is when i switch from coils to air and hit write settings and go back in later it reverts back to coils.

What am i missing now
