It is the suspension system... I had that problem when I had my vehicle worked on at a hobby shop...

LOOK TO SEE IF THERE ARE METAL RODS HANGING UNDERNEATH YOUR VEHICLE MAYBE THESE ARE SENSORS AS WAS TOLD TO ME...WOW, BUT YEAH ONCE THEY RECONNECTED EM EVERYTHING WAS FINE...I DONT EVEN THINK IT NEEDED TOOLS JUST PRECISE "ELBOW GREASING!"

How do i get the on bored compressor to work on my 2003 Hummer H2


There is a lot involved in is air ride suspension system ! A 60a Fuse in the under hood fuse block Marked VSES / ECAS .This is the power for the compressor . There is a air suspension control module , Ride height switch , Fuse in the I / P fuse block 4 WD 15a supply's B+ to ride height switch . There is a electronically controlled air suspension relay that the control module energizes to send power to turn on the compressor.

This system can an will store DTC"S in the control module !
Diagnostic Starting Point - Air Suspension
Begin the system diagnosis with the Diagnostic System Check - Air Suspension . The Diagnostic System Check will provide the following information:
?€¢
The identification of the control module(s) which command the system.


?€¢
The identification of any stored diagnostic trouble codes (DTCs) and their status.

The use of the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located.
If you don't know about this stuff , I strongly suggest you take it to a repair shop ! Do you know about electrical circuits , relay's fuse's ? Do you know how to use a volt meter, read a wiring diagram. The first thing to do would be hook up a scan tool ,not a code reader. This system can set several DTC'S -diagnostic trouble codes.
DTC B2795 DTC C0563 DTC C0569 DTC C0626 DTC C0631 DTC C0660 DTC C0696 DTC C0702 DTC C0707 DTC C0711 DTC C0712 DTC C0713 DTC C0716 DTC C0717
You need to be able to test for B+ at different points in the wiring !

How Do I Fix Service Ride Control warning on Dash, And what is it?


  • The magnetic ride control system senses speed and oscillation of suspension and adjusts shock dampening for a comfortable ride. If a shock is bad or the suspension sensors are damaged in anyway the system deactivates and does to a default setting, and the warning comes on. Did you hit any real bad potholes? or probably just wear and tear.. You need to have your suspension system checked.. shocks, control arms, alignment, etc.

Service ride control 05


No. This is basically telling you that the electronic portion of the suspension system has a fault. All the basic mechanical items will still work as normal. It is common on those truck to have the Auto Ride pump go bad for the air suspension in the rear.

Suspension issue with my RR


The system has a ride control module (computer) you must take it to the Rolls dealer service dept and have the systems control and monitoring computer memory read to see what fault code or codes are stored for the light you say you see on come on while driving. Once the code is read a technician using special equipment will perform the appropriate diagnostics and repair the cause of the problem.

2003 Yukon Denali has Service ride Control Warning..wat to do?


Hi Jose:
The first place to start is to have Ride Control Module scanned for trouble codes, this requires a high end scan tool. Most common problem is the air compressor in the rear or a height sensor. Here is how the system works.

Automatic Level Control Description and Operation
The RTD system is bi-state real time damping system. The Suspension Control module controls the suspension damper solenoids and suspension position sensors, along with parts of the automatic level control (ALC) system and electronic variable orifice (EVO) power steering system.

The Automatic Level Control system consists of the following:
• Suspension Control Module
• Compressor/Leveling Module
- Air Pressure Sensor
- Exhaust Solenoid
• Compressor Motor Relay

The objective of the Automatic Level Control System is to provide constant ride height at all load conditions. The Suspension Control module monitors body-to-wheel height, and vehicle speed.

The Suspension Control module will use the rear body-to-wheel displacements and vehicle speed inputs to keep the rear trim height of the vehicle at its desired level.

The electronic suspension control (ESC) system is bi-state real time damping system. The ESC module controls the suspension damper solenoids and suspension position sensors, along with parts of the automatic level control (ALC) system, if 1500 series.

The ESC system consists of the following:
• The ESC module
• The compressor/leveling module, if 1500 series
- The air pressure sensor, if 1500 series
- The exhaust solenoid, if 1500 series
• The compressor motor relay, if 1500 series
• The steering handwheel speed/position sensor
• The suspension damper solenoids
• The suspension position sensors

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

Where are the leveling sensors located on a 2003 Navigator?


There is one at each wheel. here is some info

Vehicle Dynamic Suspension The four wheel air suspension system is comprised of the following components:
  • service switch
  • control module
  • two front height sensors
  • one rear height sensor
  • compressor and drier assembly (includes vent solenoid)
  • air lines
  • front and rear air spring and shock absorber assemblies
  • four air spring solenoids
s3j~us~en~file=ani_caut.gif~gen~ref.gif WARNING: The service switch for the air suspension system must be shut off prior to hoisting, jacking or towing an air suspension vehicle. This can be accomplished by turning off the air suspension switch located in the jack storage area in the rear of the passenger compartment. Failure to do so may result in unexpected inflation or deflation of the air springs which may result in shifting of the vehicle during these operations.
s3j~us~en~file=ani_caut.gif~gen~ref.gif WARNING: Do not remove an air spring under any circumstances when there is pressure in the air spring. Do not remove any components supporting an air spring without either exhausting the air or providing support for the air spring to prevent vehicle damage or personal injury.

Cadillac part rss module


ok this is the module to control the electronic suspension
jusk ask for the suspension module to any yonk yard
or pick up part, but i have to tell you something a had a cadillac
giving me false codes information for the suspension and also i did had a message on the digital dash, since is been a few yrs since i fix it, i tough it said service ride control, any way the problem was a ground problem the thick ground wire going to the module was having a high resistance problem meaning the ground was poor, the solution i took was adding another grond from the car budy to the suspension computer ground i weld an extra wire and had to drive the car for a little while and that took care of the problem, and actually that computer was behind the rear seat but on the lugage compartment,
and if you want some wiring diagrams go the public library or
go to autozone.com and buy the repair information from alldata for this specific car, it will cost you something but nothing similAR to the 1200 good luck and any more questions? feel free to ask
