Two Quick Question...

Ok, #1: Why when you are raising or lowering the car, and you only open one of the solenoids i.e. left/right, does the entire front or back change?

#2: How can I use (I think) Pin 11 to rig a computer bypass on/off switch? Does it need power? Ground?

Thanks! –J

What are you trying to accomplish?

According to the "solenoid mod", you disconnect power to the suspension computer via pin 21 while simultaneously disconnecting the message center feed via pin 12. This effectively disconnects power to the suspension computer and disables the input to the message center.

Pin 11(air suspension switch input) is a normally closed circuit to ground.

I cant help you with the electrical stuff but: If you are going to lower the car by adjusting the sensors, there is only one rear sensor that controls the height of the whole rear. (hence - load leveling). The front sensors control the height of the one side only. (side to side leveling).

Ok, here’s what I’ve got so far… I just put in a 6 switch setup (I know overkill I’m sure), so I have 1 switch for the compressor (UP), 1 for the compressor vent (DOWN), and one for each individual wheel solenoid (LF, RF, LR, RR).

Now, I don’t care about the air ride warning message “switch off” so really all I’d like to know is how to shut the computer down, without having to stop and go in the trunk. I was planning on a seventh switch anyway, and it would be convenient if I didn’t have to run wires from the trunk.

I was thinking Pin 11 would be a good bet since it would be just like flipping the switch in the trunk. This also seems to make sense as I wouldn't have to restart the car to get the computer to take over, I could just turn it back on.

Now the other thing, which is really more a point of curiosity then anything else is that because I have a switch for each wheel, I would seem to make sense that if I open for example the LF solenoid and turn the compressor on, only the LF should raise up, however both front bags will fill, even if the RF solenoid is closed.

So, how does that work?

Thanks! -J

Well then simply interupt circuit 425 at pin 11 with one of the switches. If you do it at the suspension computer in the RH kick panel, the message center lead will still be grounded via the switch in the trunk and you may not get the 'air ride switch off' message.

I think the sway bar has a lot to do with both sides coming up even though only one side is being lifted. I don't think both bags are filling.
