ABS Failure

Hello, my car passed quickly through 2004 model 307 puddle and my car gave abs malfunction. I stopped the car when I wanted to move again The steering did not turn and the electricity coming to the indicators goes and goes. I would like your help on the subject.

I recently came to my head, gave the malfunction, stopped the engine, started it again, looked, did not go, obviously did not care, looked at the abs circuit, there was no problem. Then I went to the usual master, connected it to the computer, we deleted the error, and when we went to the test, it burned again. We connected it to the computer again and found the right rear abs sensor error. the right rear tire was removed and went down to the sensor. My master did it if you got into the mud, he said sometimes, whatever he said, we cleared the error, we did not do it again.

Could the alternator belt be broken? When you lift the hood, take a look at the belt seen from the open next to the engine.

If there is abs error, airbag error, if there is stiffness in the steering wheel, it may be related to the alternator. In the service, this piece is very expensive.
