Just curious, but how do you know it is bad?
Usually EPS failure is the intermediate wiring harness between the module and the torque sensor.
Just seems odd that you're sure it is bad, but don't know where it is located.

^..............agree.
Most times this is just due to having coolant run out of the overflow tube and onto the PS connectors.
Where did the OP go?
Needs to answer how he/she knows it's bad.

Unless I missed something in the manual, the power steering is electric and requires no ecu. If you checked under the Power Steering search you would have seen that the harness is subject to failure. I ended up having it wired direct and did away with the electrical plugs. Never had a problem since.

Look in the pic that I provided. It is the cover on the far left. I don't expect this to work and each ECU is common only to that car. There may be a way to have the dealer reflash it to yours. Be sure and disconnect the battery before playing with the ECU.

I'll be dammed.....you are the first one I have heard of that replace the ECU and the car still worked with out reflashing. I guess there is a first time for everything. Sure would like to know how you determined it was the ECU. Might want to do a diy on the testing that showed you what was wrong.....

Remember Phil.....there is the ECU and then there is the power steering module(ECU). That is located below what you and I would normally call the ECU. The power steering module really isn't car specific.

I know this thread is pretty old but I am having EPS issues myself. I’ve already replaced the rack and the harness and the shop that’s been working on it says they it’s the module that’s now the issue. They claim they can’t work on it because it requires the dealer. Can I replace just the PS module myself or must the dealer be involved? Thanks!
