I replaced my compressor and rear shocks in August and that fixed my SRC message on the dash. The system also uses wheel displacement sensors to determine the position of the wheel and calculate ride height. As weight is added to the rear of the vehicle, the position sensors signal voltage inputs change. A great read. 1000 dollars later and it works like a charm!! Help. you'll see they have a rubber boot around them. This allows for the fail-soft actions to be taken whenever a malfunction condition is current, but requires the malfunction to be current for a certain number of ignition cycles before the corresponding malfunction code and message will be stored or displayed. step 20). 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. I just found out that I have this system in my 2001 Suburban 8.1L 4x4. If a ball joint fails, the driver loses control of the vehicle.

I have an '01 suburban 2500 with auto ride (ride dampening), i have replaced the shocks with standard shocks and installed the 22ohm resistors in their place, but i also have a bad ride height sensor. On Thursday, Nov. 1, nearly 5,000 Auto Value and Bumper to Bumper automotive professionals wearing matching yellow shirts will begin their festive walk from the Mirage hotel to AAPEX 2018 at the Sands Expo, temporarily shutting down the busy Las Vegas Boulevard along the way. Either way, moisture or a leaking shock, you'll probably need new ones. To my surprise the screws that hold the compressor to the bracket have a rubber type spacer with a metal inside that fits around the screw to i guess seperate the compressor from actually rested metal on metal.(in case you havent realized already..i am not really at my best when it comes to working on cars)so..my compressor, every time it kicked on, actually was vibrating loosely which made it sound loud..so..pressed for time i ran to parts store to look for said spacer with the metal inside which noone carries except for i was told the dealer..welllong story shortmade a make shift spacer myselftightend down as much as i couldstill can hear it when it kicks onbut not so much.i guess it would be impossible to not hear it at all when it kicks onsooh wellgot cold..havent been to dealer for correct spacer jim334, by bypassed the compressor, (I don't recall your particular model year - if the autoride is only for the rear suspension or all 4 corners) all shocks are operating without air-pressure which potentially can damage them. All engines have a mark on the crankshaft pulley for TDC, and a pointer or marker on the engine block where that pulley mark should line up. The Shop Squad is assembling to advance the automotive repair industry through ediucation, resources and dialoge. I was referencing the sensor that measures the frame to suspension height. 5. 4.
