U2105 what is this code trying to lead me to

This can be a tough one. Its basically a can communication code. It could be a few different modules or a connector/wiring. Start here though. Check out the bracket for the accelerator and brake pedal. There is a moduel called the vehicle communication interface moduel (vcim). Look at the wiring and connector going to this moduel. Make sure its intact and the wires are not twisted or broken. Alex
