Service ride control

V8 all wheel drive automatic 98,000 miles.

My SUV has the service ride control message that keeps appearing. I hear that there may be some connection with the fact that I just recently put brand new tires on it.

What does service ride control mean and how do I fix it? Is it a serious problem or something I could continue with?

I went to two parts store's and both attempted to retrieve the codes through the service port under the dash. Neither of their instruments could read anything through that service control module or whatever it is called. They figured that I had a fuse that was out to that module but I checked every fuse in the fuse block and they were all good. Is there something special about that diagnostics port on this vehicle or is it common not to be able to get any information from it? Any recommendations on how to retrieve the codes otherwise?

Do you
have the same problem?

Does the scan tool that is trying to retrieve codes even power up? The connector is powered by the cigar lighter fuse(15a), and the lighter is a magnet for coins, gum wrappers, ear rings, etc, all of which blow fuses. It is in the under-hood fuse panel.

Okay, I finally got the code. Here it is:

C0660
Level control exhaust valve circuit malfunction.

Mine ended up needing a new auto ride compressor. Apparently there was water that got in and started to rust. I pull a boat once in a while with my vehicle and that may have been the contributing factor. They removed the auto ride compressor and tested the exhaust valve and found an open circuit in the valve.

The replaced kit was an auto ride compressor part number 15254590. The Diagnostic code was C066.

I would go to a mechanic you trust and have them pull the diagnostic code to see what that code is. Not an Autozone or the like because all they can do as I understand it is read the codes that are generated from the "check engine". My check engine light never came on, just the digital display that said service ride control.

The bad news:
$498.00 for the kit.
$144.00 Labor.

My 2003 Cadillac Escalade has the service ride control message that keeps appearing, and yesterday the Stability SYS disabled and the service brake system message appeared. I took it to the mechanic, and only the C0660 code was diagnosed.

Can the auto ride compressor be the cause of all the messages? The mechanic also said something about the cushions, but I changed them almost a year ago.

I have the same problem and same error code - and this is the second time!

I had the auto ride compressor replaced six months ago by the Cadillac dealer.

Hopefully there will not be additional charges to fix it again. When I start the engine there seems to be a vibration from the console and I noticed the compressor sound is no longer apparent.

I had also experienced the stability SYS problem (more money) soon after the compressor replacement.

It almost requires the use of a scan tool. For one to read the codes, check data, and perform system functions. If you can at least get a code, there may be some assistance available here.

2004 Cadillac Escalade V8 two wheel drive automatic 95,000 miles.

My service ride control on the DIC came on earlier. And I do not know what that means. Looked it up in the owners man and it said a problem with my suspension?

It would have a relevant fault code stored that would need to be extracted to establish a repair. A scan tool or code reader is necessary, but not all code readers will interface with most vehicle sub-systems.

Service ride control, code CO580 what is the part? Is it part of the shocks?

Test 10-12

Circuit Description
The suspension damper solenoid is driven ON and OFF by the Electronic Suspension Control (ESC) module. To activate the suspension damper solenoid it is initially subjected to full battery voltage for a short period of time. Once the suspension damper solenoid is pulled-in the supply voltage is Pulse Width Modulated (PWM). The amount the suspension damper solenoid valve is activated is based on inputs from the driver Tow/Haul Switch, road inputs, position sensor inputs and the Powertrain Control Module (PCM).

Conditions for Running the DTC
The ESC module performs a test on each suspension damper solenoid during both the ON and OFF states.

Conditions for Setting the DTC

A short to ground in the control circuit of the suspension damper solenoid.
A short to voltage in the control circuit of the suspension damper solenoid.
An open in the control circuit of the suspension damper solenoid.
An open in the solenoid low reference circuit of the suspension damper solenoid.
A short to voltage in the solenoid low reference circuit of the suspension damper solenoid.
Action Taken When the DTC Sets

The suspension damper solenoid will be disabled.
All suspension damper solenoids will be disabled.
The SERVICE RIDE CONTROL message will be displayed.
Stores a DTC C0575, C0580, C0585 or C0590 in the ESC module memory.
Conditions for Clearing the DTC

The ESC module no longer detects a problem in the low reference circuit or the control circuit of the suspension damper solenoid.
Using the scan tool.
A history DTC will clear after 100 consecutive ignition cycles if the condition for the malfunction is no longer present.
Diagnostic Aids

Important: Ignition cycle counting is used by the ESC module to detect faults in the system. The objective is to eliminate false/intermittent codes while maintaining an acceptable level of system performance. The operation of the ignition cycle counting requires that a fault condition be present for four consecutive ignition cycles before it will set the fault code and display the "SERVICE RIDE CONTROL" message. If a fault code is present (without a fault being current), the system will go into one or more degraded modes without displaying a message. Resetting the ignition cycle counter is done by clearing codes with a scan tool. Clearing codes will override ignition cycle counting for one ignition cycle. Therefore, a fault condition will set the fault code immediately if it occurs on the first ignition cycle after the codes are cleared.

If DTC C0870 or C0690 is present, repair the malfunction for these DTCs before diagnosing DTC C0575, C0580, C0585 or C0590.
It may be necessary to check Testing for Intermittent and Poor Connections.

Test Description
The numbers below refer to the step numbers on the diagnostic table.

Checks control circuit/control module.
Tests for low reference circuit of the suspension damper solenoid. The ESC module supplies ground of the suspension damper solenoid.
Verifies that the resistance of the suspension damper solenoid.
Tests the control circuit to the suspension damper solenoid for an open and short to voltage.
Tests the control circuit for a short to ground.
Replace and program the ESC module.

It is not as easy as a part. A code never identifies a bad part, just a failed system.

You need a shop to help you with this.

Roy,
Thanks for the response. I did see a shop-that is how I got the code, but he said the suspension damper "solenoid is inside the front shock absorber so the shocks need to be changed". He quoted $600.00 each so that is why I was investigating further, and thus the question if it is in the shock.

Yes it is. The price sounds about right if that includes the labor.

I also found some aftermarket shocks that are at least a little less than Cadillac direct. Would they work okay with the system?

I guess more specifically - they are electronic shocks, would you expect that they work with the ride control satisfactorily, not just fit mechanically (mounting)?

Usually my auto suspension in my 2006 Cadillac escalades hums when I'm on uneven ground. It was really loud today, more than usual. Any suggestions? It has been a little colder than usual. Not sure if that has anything to do with it or not. I would appreciate any feedback or suggestions about this issue. Also, if anyone has any questions for me, feel free to ask.

Yes, they may not give you the ride quality, but that is why the factory ones are a lot more money.

If the pump runs and it turns off like normal, most likely all that happened is the mounting bushings have gotten hard in the cold weather and are transmitting the normal noise better, or they are deteriorated and the metal bracket is rubbing on one of the mounting bolts. Other bushings will also be harder when they're cold and they will not isolate noises very well. That is why cars make as much noise in really cold weather as our bodies do. I would not be too concerned yet unless the noise gets loud on a warmer day.

Hello,
I have code co580 only.
Is this the right front air ride sensor?
Is the sensor the one with the arm connected to the suspension?
Are these repairable?
Thank you
