2006 Chevy Trailblazer 4200 Straight Si Cylinder. Service Stability , TRAC.
Computer codes  C0455 and c0244.

Question = Why is my service stability light on the dash as well as the
Traction warning on 2006 chevy Trailblazer.
The repair shop i took it to scanned and said code C0455 , c0244, but they dont know what is
wrong with it. Any help appreciated and donation to follow, thank you.

2004 chevy trailblazer.
Question = what should i be looking for when code p0455 comes up....evaporative emission control  
system leak detected (gross leak).

Code p0455 is a large EVAP leak.
A common cause for this is a loose or faulty gas cap. Or if the truck was running when you were filling
it with gas, this can also cause this code.
Another common cause is a faulty / sticking
EVAP vent solenoid / valve. If the vent  valve does not
operate, the system will not seal when it needs to, thus causing a large leak. A simple test with a test
light and a scanner that can turn the vent solenoid on and off would need to be done to test the valve.
A common cause for this warning light and the codes you are getting is a failed Steering Wheel
Position Sensor.
This code is very intermittent and hard to diagnose. Even with the proper scanner to view
stability system data, the sensor is usually operating correctly at the time of diagnosis. There is
also a service bulletin that refers to a wiring harness that may cause these codes, but most all
of the time it is the sensor. The sensor is not hard to replace. Takes just 15 minutes or so. If you
would like, i can send you instructions on how to do it.

Yes, please send those instructions. I have made a tip / donation just a few minutes ago, thanks.

Thank you very much. I will send that info right out.....

Question: Would the ABS module not working throw a u1000 communications code causing my service engine soon light to come?

Answer: Yes, it can. A u1000 is a general communication error. It could be the ABS module is bad or a wiring problem.

How can i track the wiring problem to the abs system because the scanner threw all 4 abs sensors and the pump.

First check the fuses and then disconnect the module and look for broken or damaged terminals.

I've checked all the fuses they look good my problem is i don't know where the abs module is at on my 2002 Chevy Trailblazer.

On the chevy trailblazer, it is located under the truck, drivers side, sort of behind the drivers seat.

Thank you one more question. The code reader said that i have 4 incomplete modules can this abs module cause that because theirs
no other codes popping up other than the abs codes.

Yes, it can. When one module is having a communication problem, it can effect other modules on the data line circuit.

Thanks, you have been great !
