SOURCE: wont complete scan to pass emission test

When you rest your codes there is a series of tests your ECU has to go through before you can pass emissions. this is done some people can reset the code and go before its sets the code again. on the 96 you can have 2 tests not complete for it to pass. basicly you have to drive the car a couple days for the tests to pass.

check the readiness tests wait until only 2 have not passed. then you should be good.so drive and check.

SOURCE: Did not pass state inspection (vehicle)

First the fault codes,
U110C is No Fuel Level Bus Message
U0155 is No Cluster Bus Message.
Unfortunatly you have to be able to communicate with the instrument cluster with your scanner to diagnoise and I do not think an aftermarket scanner can do this.

SOURCE: I FAIL THE EMISSIONS CODE# P0410- SECONDARY AIR INJECTION

I have a 2001 STS that had the same problem - Service Engine light and returned the P0410 code. It ended up being a small rubber hose that had pulled off one of the plastic lines in the secondary air system. In fact, I just fixed this last night.

Pull off the top engine shield (the one covering the motor and the fuel injectors, not the plastic one at the front of the car) and look for loose lines, hoses or wiring.

Also - if you remove the shroud under the engine (you just have to pull out a bunch of plastic retaining plugs) you can get at the lower elements of the SAS. Look for loose lines, hoses or wiring.

You could be fortunate and just have a loose line. Does the caddie run OK?

Cadillac escalade transmission problem TFP switch trouble code and how to fix the delay shifting my car is cadillac escalde 2008


Transmission fluid pressure switches, i would say you have internal transmission problems, weak pump or internal leakage but to have four bad pressure switches is very very unheard off, i would have a transmission shop check it and maybe do a pressure test and leak test. it sounds like it may be time for a rebuild on that transmission.

Cadillac escalade ext will not start dic message says service battery charging system i'm reading 12 volts on battery but it act like a dead battery not charging system


A battery can read 12 volts yet be weak in cold cranking amps, try a jumpstart and if that works have your battery load tested. Im betting your gonna find the battery fails the load test, meaning it needs to be replaced..

WHEN I START MY ESCALADE IT JUST CRANKS BUT WILL NOT START, BUT WHEN I TRY THE SECOND START IT STARTS NO PROBLEM. WHEN STARTED IT SEAMS LIKE IT HAS LOW POWER


Get in the car and turn the key on, but do not start the engine. Do you hear the fuel pump running? After it runs for a few seconds, try to start the car. If it starts every time, then the symptoms you describe combined with the test indicate a failing fuel pump. Sometimes you can get codes from the cars computer which also provide some indication of what's failing. It could also be the fuel pressure regulator on the injector fuel rail

2002 cadillac escalade driver side back window stuck.


If you cannot operate the window from either switch, I'd first test switch continuity and operation, both front and rear. If they both pass muster , I'd have to say the fault lies behind the door trim, probably the motor, which also be tested once reaching that point..
