Hi Ken, the car listed above wont enter gears, when put in D Or R, no reactions at all. I noticed the ABS unit does not appear when I scan the car for fault codes.

May I as well get the can bus for the ABS, could be a short or open circuit in the wires. I have attached image of the codes below.

Hi Adrin,

Yep, this looks like it might be the CAN BUS system, but the image with the codes is too small, I cant read it, can you please reload a more viewable version?
