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 !

2004 chevy express van codes p0894


P0894 Transmission Slipping
P1258 Engine got Hot
P1516 Throttle Actuator Control (TAC)

Chevrolet Tahoe vehicles may experience a performance issue where they will not go over 15MPH. The vehicle may appear to be in "limp-in" mode, giving just enough power to get you to a shop. over-hood-250x300.gifThe codes indicate a problem with the throttle position sensor circuits and throttle actuator performance. Do NOT start replacing parts. Shops report a pattern failure in the electrical harness to these sensors. Chevrolet has issued a revised replacement harness to correct the problem. The original connector was prone to vibration and broken wires that disrupted the signal to the PCM and put the vehicle into reduced power mode.

The reduce engine light comes on at 50 mph what could the problem be


DTC P0120 P0220 P1516 P2135 these should be the problem codes.
2003-2006 Chevrolet Avalanche, Corvette, Express, Monte Carlo, Silverado, SSR, Suburban, Tahoe, Trailblazer. for reduced engine power. p0120 is throttle position sensor, ( tps ). p0220 is relates to tps, p1516 tps is out of range. p2135 is a throttle body code, the throttle body needs replaced. but before you do it replace tps first to see if it takes care of the other codes. have a good day !!
