ABS / Traction control issue...Help! 2011 Mazda3i 2.0L

[Sme92]

I have a 2011 mazda3i 2.0l. The abs/traction control flickered on then went off now is back on and won’t go out. The scanner pulled codes U0415:92-8A Invalid data received from ABS control module. C0031:01-2B left from wheel speed sensor.

I replaced:

Front left wheel bearing
Front left abs sensor
Front left abs harness
I also followed the abs wire to the end and there’s no visible cuts/damage.
I also checked the abs/traction control fuses

I’m stumped and frustrated. Help is much appreciated.

Well, it could be the ABS Control module itself.

Always check all your grounds though. All engine grounds and body grounds. Bad grounds will cause very goofy situations.
