It’s probably your best way. With the proper diagnostic equipment the garage will scan the various modules (eg the EBCM and the Body Control Module) for any historical fault codes logged. Any historical fault codes in the modules will need to be cleared otherwise they will keep re-appearing on your hand-held EOBD scan tool.

I already scanned and cleared the codes, but they come back instantly.

Deleting the fault codes with your hand-held scan tool does not delete them at module level.
From my post: Any historical fault codes in the modules will need to be cleared otherwise they will keep re-appearing on your hand-held EOBD scan tool.

What do you  mean by "scan tool does not delete them at module level."?
Erasing the codes delete all of them, active, pending and historical.

The codes re-appear because the fault still exists, the codes will always come back if the cause of the codes is not solved.

Whats so good with the ABS system is that if you replace a faulty abs sensor, the abs light will  turn it self of ones wheel get in to motion.

If i only could get the panel of wish is above the feet then i could check the connection to the steering angle sensor to ensure that it has a good connection.
Maybe the cover round the steering column must be removed first?

I've been through page after page of body trim removal data but that is the only item I cant find.
Steering column, radio, gearbox, instrument cluster ..... but not the lower drivers side knee trim.
They do show some kind of metal plate behind (called knee bolster) but not instructions or diagram of the outer trim.  Sorry, did try.

An update took it to the chevrolet deal today.
Left the car in with the information that abs tc and steering angle is illuminated on the dash, did not inform them that i replaced the sensor.

And of course they called me in less then an hour saying that the sensor must be replaced.
I realized they only checked the code and not the sensor itself or anything else.
told them that i already replaced it but told them to do so if they where sure that its the problem.

They called me back in 3 hours, "Hi good that you told us that you replaced it it was a bad cable above the sensor"
So they are going to replace the cable harness.
I assume  it this one.

They grey connector is for the wheels, i wonder where the black connector is attached, if the must dismount alot of stuff in the trunk, or if its located inside the wheel housing.

Defective cable, vibration breaks, corroded connectors and the like are I think a primary cause of many an (erroneous)  diagnostic code reading. The problem is that the codes shown relate to the senor or component the cable services. A good example of this is the recently diagnosed turbo failure (different post) yet full testing of the turbo gets a clean bill of health.  All along it is probably just the cable or a connector. How many people pay for a new part when all it is is the cable/connector !

That my point, they should scan the codes but also perform a trouble shooting not just replacing parts.
If i never told them that i replaced the sensor, they would have done so i the problem still would remain, but bill me anyway.
Just to perform a new troubleshooting to find out that the wiring is bad, and bill me again.
