Hello, I have a 1996 318TI that I just serviced with some new brake lines, calipers, pads and rotors.

I bled the brakes a couple of times after the service and I have maybe 80% pedal.

Since the brake service, My ABS and ASC lights are on.

I scanned the codes at the 20 pin connector and received 3 codes.

21 - Speed Signal, Front Right (electrical fault)
11 - Speed Signal, Front Left (electrical fault)
93 - Engine intervention via CAN.

I tested both wheel speed sensors and they are working properly. I'm not sure what the third code is and how to troubleshoot it. Does anybody have any advice on how I should go about troubleshooting the ABS/ASC system? Also can air in my ABS pump trip these codes? If so, how can i jump the relay? Thanks -Mike
