UPDATE: No Start, Loss of Communication Conditions

Some 2015-2016 Colorado and Canyon models may have a condition of no crank/start, loss of communication, engine stall or an illuminated Service Engine Soon lamp with possible Driver Information Center messages. If any of these conditions are present, inspect the engine wiring harness for contact with the water pump pulley (Fig. 16), the oil filter housing (Fig. 17), and the engine boss near the left rear cylinder head (Fig. 18) behind the coolant pipe.

 

Repair the engine harness as necessary and route it away from these possible contact points.
