'01 Chevy Silverado 6.6L Low Coolant Level Message

Quick one on a 2 wire switch. If we see a ground on one side, and a wire from the pcm, the pcm is usually sending out a voltage to be dropped down to ground at the switch. When a switch is suspected bad, we can bypass it and verify things operate as normal. Always be careful, never give a pcm or module power where its not supposed to be.
