Grandson's truck has thrown two codes causing the wrench icon and skidding icon to appear. I looked up both codes, U210b states lost communication between fuel pump or restraints. U0151 states lost communication with RCM. I've been searching and reading for two days. I'm hoping that it is a wire issue. Any suggestions on where I should start looking for loose or damaged wires. Thanks T

 

A good place to start looking would be under and around the front seats.
Sometimes something can get caught under there and cause the wires to be pulled apart/unplugged.

 

Everything looks good under the seat. Unplugged connections and sprayed with cleaner. Still have the codes. T

 

Being told that a bad ground would cause my issues. Where should I start looking? Thanks T
