ABS help - Toyota 4Runner Forum

I need some help fixing the ABS on a 2000 4Runner.
When I stick the paper clip into the diagnostic port, I get codes 31,32,and 33. All wheel sensor codes. I replaced one of the sensors and that code still flashes when I re test. Could something else be causing it to code for 3 wheel sensors or is it more likely 3 sensors crapped out?

Abs code 31 is for the right front sensor, abs code 33 is for the right rear sensor. (right = passenger). Are you sure the system is blinking 31 twice because it shouldn't. If its abs code 21. It could be the relay on the passenger fender side. if you can access the fsm go to the abs, Trac vsc system. Often times just cleaning the sensors help since they are magnetic and attract metals.

That's great that you fixed it. Change the title of your thread to solved abs code 31, 32 and 33. Also post how you fixed it. It will help others.

Edit: your post I fixed it threw me off.

I think he meant he fixed his post, not his ABS.
