wish i had seen your great tip a month ago. we never work on anything besides diesels here, we looked at one for a friend and kicked my butt for a hole day before i found the rear hatch switch was bad, causing the wipers to not work.

Default Horror stories from the Body Shop

So the body shop sends over this 2018 Chrysler Pacifica with a check engine light, nothing new there. Found code U11E9, lost of communication with the Active Grille Shutter. Ok, so maybe a broken wire in the front bumper cover. Back probed the wires at the connector, got power and ground but nothing on the LIN communication wire. Unplug the connector and checked continuity through the wire all the way back to the PCM, all good. I even load tested the circiut with a 10 amp load, still good. I back probed the lin wire with ASG disconnected and found a good LIN communication wave form, hmmmm? As soon as I plugged the connector in the wave form went to ground. So maybe we have a bad shutter assembly ? Tried a new one, same thing, comm goes to ground when plugged in. OK so this thing has been replaced by the body shop before I got it. Pin 1 is ground and pin 2 is the LIN wire . Connector seems ok too, nothing shorting in there. I checked the resistance on the terminals on the shutter assembly Found them to be shorted on both assemblies. So looked on shopkey to check the pin outs on different model years and sure enough a 2020 is different. The ground is now pin 4 and the LIN is on pin is on pin 3. So rearanged the wires in the connector and problem solved. But why did Chrysler change the pin out ? Found that they had sent an updated wire harness to the Body Shop but they failed to install it because there was nothing wrong with the old one. The least you could do if you're going to change the pin out on something you could change the connector so it doesn't plug in !! And that was my morning.
