how to test autoride compressor

Place the vehicle on a flat level surface. In my opinion, as long as you are within the allowed carrying weight of your vehicle they should be fine, which is true for any suspension system OEM or aftermarket. 2001 suburban with auto ride, rear shocks seem fine. When the ESCM detects a steady, substantial change in the position sensor signal voltages for at least 10 seconds, it responds by commanding the ELC relay ON, which activates the compressor, causing the air pressure in the shock absorber chambers to inflate. The Auto Level Control (ALC) air compressor should be on the driver-side behind the left rear wheel wall mounted on the outer side of the frame and can be accessed from under the vehicle. They work fine now. Pressure Test With a scan tool, perform the suspension Bumpstop setup procedure by following the screen prompts. Attach the air tube to the pressure gauge on the side opposite the toggle valve. if you had a link that would be great. The resistor your wiring in at the shock just sends a message to the ESC that the shock is receiving damper controls and the damper solenoid is working properly. Notes: On board air compressor kit. I never suggested that it was for the shock. The GM full-sized SUVs (Tahoe, Escalade and Avalanche) are the choice of soccer moms, diplomats and celebrities. The ESCM also limits the amount of compressor run time to 255 seconds to protect the compressor components from thermal damage. You may want to contact Bilstein to see if they can help. Any ideas? Disconnect the air tube from the air dryer. Its important to remember not to miss a worn joint. All was peachy for 5 months. However, if youre comfortable with the idea of doing it yourself, there are plenty of online resources that can help you through the process. Required fields are marked *. The compressed air is then run through a dryer containing a moisture- absorbing chemical that dries the compressed air before it is sent to the shock absorber chambers. When weight is removed from the vehicle, the ESCM responds by commanding ON the exhaust valve causing the air pressure in the shock absorber chambers to deflate. 9. then cover with shrink sleeve? Mine no longer works and want to know where to start. The system uses the Electronic Suspension Control Module (ESCM) and the serial data circuit to perform the system functions.

Lets take a closer look at adjustable shocks and struts, what they do, and how one should go about adjusting them. Air conditioning odors typically result from the uncontrolled growth of bacteria and other microorganisms in the evaporator. On racecars, mechanics in the pit lane will tune the settings of the shocks and springs for the track. Then, turn off the engine and open the hood. In case your's is a different year, the best thing is to look under the box cover for specific fuse location for the system. Close the toggle valve.
