You need to have the vehicle put on a dignostic machine , find out what DTC diagnostic trouble code is stored in the computer that controls traction control . Your best bet would be to take to a qualified repair shop , because it sounds like your not up on these thing's

Transfcase motor not shifting


Have you had it check for DTC's - diagnostic trouble codes . frustrating because you don't know what your doing. Rookies ! I'd tell you have to test but you don't have tool or knowledge .
What transfer case does your tahoe have ?
Do you know what DTC'S are ? Your vehicle 4X4 can set a bunch .

DTC B0770
DTC B0775
DTC B0780
DTC B0785
DTC B0790
DTC B2725
DTC C0300
DTC C0305
DTC C0306
DTC C0321
DTC C0326
DTC C0327
DTC C0359
DTC C0374
DTC C0378
DTC C0379
DTC C0550
DTC C0558

DTC B0775 Four Wheel Drive High Range (4HI) Indicator Circuit Malfunction

DTC B0780 Four Wheel Drive Low Range (4LO) Indicator Circuit Malfunction
DTC B0785 Two Wheel Drive High Range (2HI) Indicator Circuit Malfunction
DTC B0790 Transfer Case Neutral Indicator Circuit Malfunction

DTC B2725 ATC Mode Switch Circuit Malfunction

DTC C0300 Rear Speed Sensor Malfunction
DTC C0305 Front Speed Sensor Malfunction
Just show a few DTC'S and for everyone of these DTC'S is a diagnostic flow chart . Do you know what that is ? It's fustrating and hard to fix something when you don't have a clue as to what your doing . Do you know how to do basic automotive electrical testing ?

This would sound about what the problem could be , but with out testing id be guessing just like you .

DTC C0306 05: Motor A or B Circuit Short to Battery or Open
DTC C0306 02: Motor A or B Circuit Short to Ground
DTC C0321 01: Transfer Case Lock Short to Battery
DTC C0321 06: Transfer Case Lock Short to Ground or Open

Do yourself a favor and save some aggravation an take it to a qualified repair shop . You do know a computer controls the 4X4 system ? transfer case shift control module .

Abslight stays on. How to fix? This is a2007trailblazer?


First you need to have EBCM - electronic brake control module check for DTC'S - diagnostic trouble code's . If the light is on there is a code stored . I think most part stores can do this and for free . After you find out what code is stored , looking up that code in service repair information for diagnostic trouble shooting chart would be next step . There are a few codes too.
DTC C0035 or C0040
DTC C0045 or C0050
DTC C0110
DTC C0131
DTC C0161
DTC C0186
DTC C0196
DTC C0201
DTC C0240
DTC C0241 or P0856
DTC C0244 or P1689
DTC C0245
DTC C0283
DTC C0287
DTC C0290 or C0292
DTC C0455
DTC C0550
DTC C0558

Find the code do the diagnostic's , fix the problem , wiring issue's , a sensor , bad module ,what ever it is . The light will go out then . Here is a sample of code discription .
• DTC C0035 Left Front Wheel Speed Sensor Circuit
• DTC C0040 Right Front Wheel Speed Sensor Circuit

2009 chevy tahoe fuel pump wont shut off


The fuel pump control module is controlled by the ECM - engine control module , Possibility of DTC'S stored ! You need to take to Chevy Dealer !
The engine control module (ECM) supplies voltage to the fuel pump control module (FPCM) when the ECM detects that the ignition is ON. The voltage from the ECM to the FPCM remains active for 2 seconds, unless the engine is in Crank or Run. While this voltage is being received, the FPCM closes the ground switch of the fuel pump and also supplies a varying voltage to the fuel tank pump module in order to maintain the desired fuel rail pressure.

I have the P0049 on my 2005 Chevrolet Tahoe. Point me in the right direction


This Diagnostic Trouble Code (DTC) means that your turbocharger/supercharger is spinning too fast. Since your vehicle is not equipped with either of those, you should check the Mass Air Flow Sensor (attached to the intake) and the O2 Sensor (attached to the exhaust manifold/header)
