Ugh... EPS failure

[Ken226]

I think there is a class action on this, another reason have someone fix it.\\\

I like my hydraulic they shouldnt have changed them

I understand why they wanted electric power steering. I don't necessarily like it, but with the fuel mileage standards being shoved down everyone's throat, I understand why they did it.

But they could have at least housed the control module and torque sensor in a separate module. Having to replace the entire rack because of a failed 8$ circuit board, means throwing away a perfectly good precision ground ball-screw, ball nut, dozens of ball bearings and linear bearings, in addition to the housing itself, is just ******* retarded. Or, the version of the word that won't get censored, it's extra-chromosomal!

If EPS units are failing after hitting potholes it would almost then seem to be a circuit board failure of some sort.

I do know that cold solder joints are sometimes very hard to spot.

I would suspect possible failure of the large capacitors, those would take the most abuse due to their size.

You could test those capacitors with an ESR meter (type that into ebay or amazon).

Just closing this one out. After diagnosing everything 7 ways to Sunday with no clear indication as to anything other than something with the rack, I installed a new one this morning. Everything is working as it should, no lights and I have power steering again. So all is good (for now).

Thanks to all who chimed in!
