NEED HELP AIR SUSPENSION SWITCH OFF
Ok guys forgive me if there's been a thread on this but I have been searching for a week and have not found any info on it. I recently got my 03 navigators air ride switched over to coils. After I got it back the dashboard says the air suspension switch is off. I went to the back hit it on (since it controls part of the power steering as well). But the dashboard still says it is off. It's driving me nuts. Can it be a fuse? I have looked at the diagram and there is no fuse that controls that switch. I am going to try fuse 20 for the air ride module and pray it works. If anyone has any idea what it can be please hold me out.

24. Unplug the Air Pump Connector C1179 located behind the
right hand head light near the air suspension pump.
25. Remove the Air Suspension Relay C1198, located on the
right hand side below the head light on the radiator support.
26. No additional items are to be completed with the Control
Module, as this is required to maintain steering inputs to the
EVO Steering Module and ride information.

I changed to coil overs on my 06 Navvy and I pulled 2 fuses to avoid that message per the instructions for the Monroe's I installed. See below. You can download the entire instructions at the link too.

The fuses that power up the ASM (Air Suspension Module) are located in the CJB (Central Junction Box). The CJB is behind the right kick panel and you are looking for fuse #120 (30 Amp) and #127 (5 Amp).
Fuse #127 is hot in start and run while fuse #120 is hot at ALL times, so you can see that the Air Suspension Switch doesn’t “turn on” the ASM. The ASM has power all the time, so it can activate itself at any time.
The Air Suspension Switch is on the ground side of the circuit so it is only used to tell the ASM not to raise or lower the vehicle when you have it in the off position.
When the ASM is off, it makes the steering feel weird (trademark) because the ASM no longer functions as a beefed up sway bar while navigating turns.

Works the other way around.
The EVO (actually its the SAS (Steering Angle Sensor) ) is an input to the ASM.
The SAS measures how quickly you turn the steering wheel.
The VSS (Vehicle Speed Sensor) measures how fast the vehicle is moving.
If you turn quickly while at speed the ASM closes the air solenoid valves between the left and right rear air springs and between the left and right front air shocks. This has the effect of stiffening up the sway bars, which makes the steering feel heavy.
If the air suspension switch is turned off and you swerve quickly, the air valves stay open, and the vehicle leans over toward the outside of the turn (think big old Grayhound bus), which makes the steering feel like is super boosted.
