Greetings and Welcome to Just answer.
Take the battery cables off the battery, hold the ends together for 10 seconds then attach them to the battery and see what happens. This will reset the whole vehicle.
Did not work
Is it a picture of the oil can and a wrench?
Ok, that is a warning that there is a fault in the BCM side of the car. It could be a light out. You need to use a scan tool for this. A scan tool is very different than a code reader. Scan tools are larger, can scan and control certain systems of the whole vehicle, and usually cost about 2000+. A code reader will only read emission related codes and that limits them to reading the engine and transmission modules. Given the cost of the scan tools, it is usually cheaper to get a shop to read the codes. If they are honest, I would imagine that $20 is fair to stick the machine on and read codes.
