ABS code C045 and C0550

[72chevs]

The vehicle I have is a 2004 Suburban. There were other codes. When I cleared them, these 2 still remained. I believe C045 is for the Left rear wheel sensor and the C0550 has something to do with the ECBM. If I am not correct, please correct me.

 

I checked voltage from the harness that connected to the sensor and it was 3.6 volts. Check the right side (no codes on that wheel) and the voltage was the same. Figured it might be the sensor. Replaced and still has the same code set.

 

Wondering if anyone had the same issue and where I can get info to repair.

 

Thanks
