So I have the dreaded ABS lights on. ABS BAS ESP ETC
I bought a Scanner and these were the codes:
The signal from component N49 (Steering angle Sensor) is faulty
C1100 Left Front Speed Sensor
There was also left front speed sensor implausible speed, another SAS error, and a right front speed sensor error.

I didn't think it reasonable that all 3 of those sensors would go bad at the same time.

I've done some searching and did the steering wheel left and right to reset the Steering angle Sensor, I've checked the battery and charging, I checked fuses, I tried to see if any sensor wires had rubbed against the body or wheel wells.
I watched a video where somebody just cleaned off plugs with CRC electrical cleaner so I tried doing that. Well, a couple errors went away but several more popped up.
So the left front speed sensor implausible speed went away, and the right front speed sensor error went away, but now I'm left with:
C1120 -- N64 (ESP Yaw Rate Sensor)
C1035 -- The signal from component N49 (Steering angle Sensor) is faulty
C1038 -- Engine Control Modul Not Identified or Incorrect Control Module
C1027 -- Fault in CAN communication with control unit N15/3 (ETC[EGS] Control Unit)
C1045 -- Fault in CAN Communication with Control Unit N78 (transfer case control module)
C1046 -- Fault or Defect in CAN Communication
C1022 -- CAN Bus Fault
C1037 -- Fault in CAN Communication with componen B24/15 (Rotary Speed and Lateral aceleration sensor)
C1174 -- Steering Angle Sensor is Not initialized
C1100 -- L6/1 (Left Front Speed Sensor)

I also have 4 OEM Enhanced codes:
P20CB-008 -- No CAN message 'Vehicle Speed Signal Left Front Wheel' from control moduel N47-5 ...
P20CC-008 -- Rough Road detection (by comparing wheel speeds) ...
P2403 -- Teh left front wheel rpm signal sent from the traction system via the CAN bus is implausible
P2310 -- CAN Communication with the Traction system is faulty ....

So, one thing I haven't had a chance to do yet is to make sure I got everything plugged back in together securely, which might be an issue with all of the CAN issues?

Ideas?

I started down this path because I didn't want to just start replacing this sensor and that sensor, and as I stated previously it didn't seem like it was actually a sensor issue since all the lights came on at the same time and 3 or more sensor failures at the same time didn't seem as realistic as a signal interruption or something else going to the unit that reads and interprets the sensors.

If you've made it this far, thank you very much and I welcome any suggestions.

If it's important, I used the Zurich Z13 scanner and erased the codes several times during all of the trouble shooting and they came back.

have you ever solved this particular problem? if yes, what was the diagnosis and what did you do to fix the problem?

The brushes on the abs motor need to be replaced. It’s a few dollars for the brushes.

are you answering for bubbleman, the OP, or just guessing what the solution to bubbleman's issue might be...?
