    Service ride control message

    Hello,
    My 2004 Escalade ESV has completely bottomed out in the back and the air compressor runs a lot.
    The ride is getting worse and it now bottoms out over most all bumps.
    I went to my local auto parts store and they said that two types of air shocks are available, how do I find out which one I need?

    Are there any other things I should look into before I replace the shocks?

    Thank you in advance for your thoughts.

    It depends on how you like the stock auto ride system
    Some members swap the stock shocks for gas shocks
    Others(like me) replace the stock shocks and compressor and keep the stock auto ride system

    Or get passive air shocks like those from Arnott and keep the air ride without the OEM cost.

    Re: Service ride control message

    Mine has this up, ive just replaced all 4 TPMS senders on the wheels (IPM i think they where), $290 (Canada) for all parts and wheels, removed, balanced and put back on (and programmed).

    I only have the Ride Control message now. My compressor works, i need to look at the codes, but i want someone else who knows where there doing.

    I know the compressor was replaced, but the message has been on since then, so i might just get another compressor.... will look in to it, the message drives me nuts!

    Along the same topic, do the Arnott rear shocks function exactly the same as OEM? It looks like the Arnott FRONT SHOCKS have a gadget that plugs in to fool the ride control system.

    The new (not rebuilt) Arnott REAR SHOCKS look like they have the same air inlet plug in and the same wiring pigtail plug in built into the shocks (ie,they appear to be just like OEM). So do the rears work the same, because the fronts seem to use some electronic tom foolery. Just what does the two wire electrical plug on each rear shock do?

    Arnotts website isn't really clear on if their rear shocks function the same as OEM.

    Re: Service ride control message

    Ive had a look at the wiring....

    There is a controller (under rear HVAC), each damper has a sensor (front and rear), each wheel has a suspension height sensor (front and rear, mopunting on the chassis with a link to the arm / axle) then a pump with a pressure sensor.

    So this means for the complete unit to work, all 4 shocks need to be plugged in and the positoins sensors need to work, need to pull codes, and check if cables are in i would think.

    Re: Service ride control message

    Ok, that makes sense. From what I can see reading further on Arnotts site, the new and rebuilt rears do interface with the electronic dampening but their fronts do not. I am thinking of going with new rears from Arnott and probably OEM for fronts which I assume are AC Delco.. I just put in a new compressor assembly made by Dorman.

    TCM,

    AC Delco lists several different part numbers for my 2003 EXT. Any idea on where I can find the right number? I might just try to call them on Monday. It looks like I can probably get them online through Amazon for about $225 for the OEM fronts compared to $214 for the Arnott fronts.

    I read somewhere that some make (on Amazon) was trash, however i cant remember which, i do remember it needs to have the OEM plug, they seem to be ok, its the ones with loose wires you "tap" in to the truck harness tend to fail after about 6 months.

    I go to the dealer, talking about how good the truck is then ask for a quote for parts with my VIN number, i walk out 10 mins later with a written quote AND PART NUMBERS

    Good idea. The dorman part is a complete replacement just like the OEM part. It also had a lifetime warranty. No wires to splice. Here's a pic of what I got.

    Re: Service ride control message

    Do you have a dorman part number?
    Mine was done 3 years ago, however i am hoping he didnt cut any wires off, also i will be making a "protection" cover as i am sure when i looked at this its right next to the rear left wheel, about the distance it takes to cover it every bit of water the wheel flicks off (including salt).

    I think my problem are the shocks, i notice the front ones are yellow, they cant be OEM!

    Here's the part number for my truck (2003). 2007 and later used a different plug and use a different part number. I know this one will at least fit 2003-2006.

    Re: Service ride control message

    Ok, to follow up with anybody wondering, I just got off the phone with Arnott. Their web site reads like their shocks use the factory electronic connector to interface with the shock but they do not. The guy I spoke with said the plug on the rear shocks are basically a resistor to fool the vehicle into thinking the factory shocks are installed. He did say they have heard good feedback of their product.

    It looks like the only way to maintain the factory speed dampening is to go with the OEM parts front and rear. I don't know how much of a difference a guy could feel between the two but there is the answer anyway.
