Question about 2004 Chevrolet TrailBlazer
There are no codes because as far as the system is concerned it is working properly. What's happening is this:
One of the abs speed sensors is detecting no movement on the wheel even though the wheel is still moving, a-bit very slowly. The other sensor(s) is detecting wheel movement properly. The system determines you are in a skid and engages the ABS/TC system. Crisis avoided as far as the PCM is concerned.
You'll need to get a scan tool that can read the ABS system and monitor the individual readings of the abs sensors as you are coming to a stop to identify which sensor needs to be replaced.
Or take it to your local automotive technician and they can diagnose and repair it for you.
