Hi My name is ***** ***** code is telling you the abs pump motor has failed. i believe the first thing to do is check the fuses for the abs system.

Expert:  david craig replied 1 year ago.

usually if you've used cobb and its still faulting you will need to replace the pump motor

Hello and welcome to JustAnswer!

This code is for the ABS pump motor circuit. It can be set by a missing or poor power feed to the ABS module or the module itself but is most likely the pump motor. If fuses are good then it would be best to test the module power and ground feeds. I've also sometimes used a headlamp bulb to simulate the load of a pump motor to verify pump motor circuit codes would go away, then the pump motor can be condemned without having to worry whether the module had an internal failure.
