My Pete rebuild

You've been noticing that with freight too? Grab it while you can. If it's short lived then you got some while its here. If it's a true economy busting at the seams to get going then you're in front of a massive year and ride it comfortably and enjoy what I assume is much needed relaxing and efforts put else where... and so goes the life of a good O/O truck driver.

As far as the A/C deal. Did you have to unplug anything on the truck to hook up Insite for monitoring? ELD? Maybe you unplugged something that is causing interference and making the cab controller glitch.

Also, monitor closely sensor voltages. Like the A/C high pressure switch, the fan solenoid oil temp sensor, coolant temp sensor maybe even the jake on/off switch (the ecm could be thinking the jakes have been engaged for 30 seconds and demanding the fan on) and anything else related to turning the fan on. All it takes is one of these sensors to flicker for whatever reason and the fan comes on for an alloted amount of time.

Other than that, can you use ESA to monitor what the CECU is demanding on the system. I never got a chance to use that program so I'm just guessing what it might be able to show you.
