I have a 2003 Chevy TrailBlazer with 84,000 miles on it. I bought it from a used car dealer 2 months ago. Changed O2 sensor, battery, and cleaned the throttle body.
Last night the check engine light came on. This morning I took it to Autozone and they read off 29 trouble codes. I was told there were ABS codes and about 25 of the codes were communication codes.
The technician said it was possible the ECU needed to be flashed and I could take it to the Chevy dealer to see if they could do that.
Does anyone have any information on this type of issue? Are there any recalls on this vehicle dealing with this issue?
Any help would be great!
Thanks,
Josh
