--------------------------------------------------------------------------------

This bulletin is being revised to update the information for DTC C0475. Please discard Corporate Bulletin Number 07-02-32-007A (Section 02 -- Steering).


--------------------------------------------------------------------------------

The following diagnostics might be helpful if the vehicle exhibits the condition(s) described above. Use the appropriate recommendation based on what symptom has occurred.

No DTCs
Review Corporate Bulletin Number 05-02-32-002D to assure you do not have a blown 60 amp steering fuse. The fuse can be blown during improper jump starting of the vehicle on the HHR and ION. Check for this particularly for tow in conditions. DO NOT replace the steering column unless an internal short has been identified in the column that is causing fuse to blow.

Power Steering Warning Message on DIC with DTCs C0176 and C0476
This condition is often the result of excessive lock-to-lock turns of the steering wheel, causing the thermal protection in the power steering control module (PSCM) to take the steering motor temporarily off line. This is a normal operating characteristic of the system. DO NOT replace the steering column for this condition. Refer to Corporate Bulletin Number 06-02-32-002C for additional information.

Power Steering Warning Message on DIC with DTC C0550 in the PSCM
Inspect the motor harness connection to the PSCM. If no connector problems are found, replace the steering column ONLY as this is an internal controller issue.

Power Steering Warning Message on DIC with DTC C0475 in the PSCM
Check the connection between the EPS motor and the power steering control module (PSCM) by ensuring the harness connector is properly seated. If the connection is normal, replace ONLY the EPS motor.

Note: If the DTC resets immediately following motor replacement, replace the steering column.

Power Steering Warning Message on DIC with DTC U2105 and/or U2107 in the PSCM with any other U codes
Although the code(s) appear in the PSCM, these are communication codes and are not the result of a problem with the column operation or the control module. If the codes are in history, clear the codes and re-key the vehicle a few times to see if they come back. If they reappear, look for a communication issue from the BCM U2107 or ECM U2105 (wiring, connector, etc.) as the root cause. If the codes do not reappear after a test drive, return the vehicle back to the customer. DO NOT replace the steering column.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

so my steering is really really stiff sometimes on my 09... is this something i have to check out?

If it's a full blown recall, warranty won't matter. I would still talk to a service department, might be covered.

A TSB is not a recall. I have been on the phone with Gm for the past few days, still trying to get them to cover it. It is not something that comes easy, but with enough persistence it might get done. I take it in tomorrow to get the official diagnostics, then we go from there. GM might cover it because it is a major safety malfunction with the car. It is just such a big fix, prob why they are not rushing to do any recall.

I would get it checked out, the problem has only gotten worse for me. And the more people that report it the better chance for people like me to get a recall.

Exactly .....a TSB is a Technical service bulletin . It helps tech's fix issues that some cars may have ...while others may never have a problem.

Katess

Well, good news for me. GM is gonna cover the work for my car even though my warranty is done. so if you are having this problem, just keep buggng them. Or any problem for that matter. They know there are problems with these cars, just get them to fix them..

this happened to me about a month ago. im still pretty sketchy about takin my car to gm though cause all my mods and them sayin it voids the warrenty. i googled this prob and theres is hundreds of people that has had or is having the same problem with the power steering assist motor. the lady i work with brother is a gm tech and he was telling her that this part is on a long back order : / but this is deff not safe at all cause i never know when its gonna go out. sometimes it goes out right after cranking the car and sometimes later, like when i made a 5 hour trip to NC it was fine all the way there untill a min before i turned into my moms drive way lol
