hello h3.believe it or not this code indicates that there is an out of range voltage in the left turn signal driver in the vsm.the truck sees this as a saftey issue and shuts the truck down! shut the truck off,pull the fuse and relay for the turn signals and lights,put em back in.check the light clusters dont have water in them.you may have to take them off and leave them on a radiator for ten minutes.this should sort the problem out.you may have to clear the fault code from the memory.

Fact of the week
The two internal cavities in our nose called nostrils function as separate organs. Each nostril has its own set of turbinates and olfactory receptors. The two independent organs work together through a mechanism called the nasal cycle, where one nostril is dominant for air intake while the other rests and is better at detecting scents.
