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 !

The Hummer 2005 H2 sut shows service air bag Now I will check with dealer but could this be expensive


Why would you bother with a dealer after the warrantee runs out ?

Never heard of the 200,000 repair shops available,with better
results & cheaper than a dealer.

You can't ask what something costs
You do not have any idea what ,if any problems you may have

The reduce engine power message keeps coming on, giving limited power when driving does anyone know what the proble could be with my 2007 hummer H2 SUT.


The Powertrain Control Module (PCM) is shutting down your throttle body control for some reason and limiting how much throttle you can apply. The only way to find out why it is doing this is to scan the PCM for Diagnostic Test Codes (DTCs) and diagnose any existing codes accordingly. It is very likely to be caused by a fault in your throttle position sensor or accelerator pedal position sensor circuits.

There is a Technical Service Bulletin (TSB) for your vehicle which covers a known problem with reduced engine power and sets DTC P2138. The known problem is that the Accelerator Pedal Position (APP) sensor circuits are being infiltrated by water intrusion into a connector and causing erratic voltage readings at the PCM. It is TSB reference # 07-06-04-019D

Is there a reset button for the compressor-air suspension


When I replaced my air suspension bag it reinflated upon starting the Hummer. I did not have to reset anything. You may check the fuses in the event it ran so much to blow one and prevent the compressor from burning up.

DTC P0420


first, code b0100 is a fault in the restraint system. front end sensor, restraint sensing diagnostic module or communication between the 2 are suspect problems po420 is an efficiency problem with catalytic converter. most likely would need new converter, but exhaust leaks and oxygen sensor malfuctions can also set code. if this vehicle is under 80,000 miles and does need converter, dealer should repair for free under warranty. that is federally mandated.
