I would start with the easy stuff first.
First, make sure the battery is good. So many issues involve the battery, if any doubt just replace it. At the same time, undo all the connections to the battery. Then inspect, clean, and retorque them.
Next, inspect and clean the 3 wiring harness connectors and the pins going to the ECM. Both of these are common failures, if you do both of these you will probably fix the issues. If I were you I'd just buy a battery now and a can of CRC electrical cleaner.

 

Hello,

I am getting these error codes, need to fix them.

Car starts but the transmission doesn't shift. Getting errors like "Service traction control", "Service power steering", etc...

Anyone come across these before?

Any tips or links you can point me to?

I know to check the grounds, but does anyone know exactly where the ground to chcek are? Is there a Cruze Service Manual with that information I can find online?

Thank you
