Do you have the snowplow package or the standad fan? Altho it doesn't make a lot of difference if your getting no signal, your getting no signal. Clutch or wireing one of the two.

Check the connector near fan. I had a new harness put in and got that code connector was loose no more code

Not sure if it has the snowplow package. If I'm getting no signal why is it coming on though?

I have a rough idea of how a clutch fan works and I didn't think it was electrical related.

I had that code pop up on the way from Oakland to Denver pulling a small trailer. I suspect (in my case) it is either a loose connection, bad wire, or the fan clutch is going. Only happened once and hasn't been back in 4 months. Keep an eye on your temperatures (using a CTS or ScanGauge, etc...) and see if it comes back. If it keeps coming back, you need to go through the troubleshooting (haven't lokked at it, but I am sure there is a proedure to ring out the wires and so forth) Trouble is, wiring problems cnab be hard to duplicate when the vehicle isn't moving...

when I say fan clutch I'm including the wiring harness that's attached to it too. There is a tsb for the wiring getting cut by the fan but i've never seen that, it's always been resolved by replacing the entire assembly
