No Dtcs And No Warning Lights

2010 Chevrolet Camaro VIN 2G1FK1EJ4A9209169

Hi

This car came into the panel shop for slight frontal and slight rear damage repair.

The battery was disconnected and when it was reconnected the power steering was not working.

I was called to have a look.

There are no DTCs and no warning lights, I tried to reset the steering angle sensor with scan tool but no better.

I also did a hard battery reset, again no better.

All fuses and charging system checked OK.

Any help with this would be great,

Simon

Did you check all modules for dtcs ?

Hi Scott Yes, all modules were checked. Engine had a P0171 that was deleted and did not return.

Simon, Was the steering working fine before the work started? My info shows this to have hydraulic power steering. Is it electric or hydraulic? If electric, there should be codes somewhere indicating a failure. If hydraulic, I would look for low fluid, missing or slipping belt, bind in rack assembly or crushed hose. If it is a pre-existing problem then it could be a plugged screen in the pump.

Hi Michael Everything was working fine before the battery disconnect. I believe this is a variable electric steering system, I am doing more research because we don't see many of these vehicles over here so my knowledge and data on this type of American muscle is limited. I have attached a copy of the RPO codes in case that helps. Regards Simon

Simon, Sometimes control modules have a hard time waking up after the power has been cut. Do a vehicle wide scan and see if the power steering module comes up. Look at the scan data and look for anything in the torque sensor or steering angle sensor that is unreasonable. If the module does not come up in a scan then see if there is a reset in the BCM menu or ABS for the steering module.

Hey Simon this a 100% hydraulic steering. There may be a variable flow solenoid on the rack but thats it. This does not have an electric steering rack.

Hi Caleb Thanks for that, further investigation confirms that its a hydraulic system! Further checks are being done on the pump by the garage. Thanks for your help. Simon
