Active grill shutters code U11E9

[John Arrambidez]

Not voltage reading, there should never be voltage on a ground circuit. Did you check resistance? You should get a reading in ohms.

No we did not check ohms.

That’s what I would be checking next. I’m willing to bet it’s a wiring issue. Highly doubt the PCM and PDC have both failed and only the AGS circuits.

Ah, maybe the connection to the ags motor? Otherwise have to pull that entire cable run/system

Could be ya, I’ve dealt with a few wiring issue for your issue before. Usually find some broken wires in the harness near the headlight area.

When I did mine I got lucky I used a power probe to test it. The first time we checked everything was fine then just happened to move the wire and lost voltage. It was in the first few inches of the wire, I replaced it with the pigtail I bought off ebay .I think i put the link in back in the thread.

Is post 6 .

You said your shutters cycles at start up when the truck is cold? They are in the closed position at start? Then they open and then close again?

I could close mine by hand and they would open but they would not close on their own or do the self check at start up. Like I said helps if somebody watches because you have to start and jump out and run to the front or you will miss the self check.

I still keep the corroded wire on the dash because this was so frustrating to trouble shoot.

I didnt remove any I just fixed my broken wire with a new pigtail.

I used a power probe it will even check grounds for you.https://www.powerprobetek.com/product-category/circuit-testers-new-new/ I have a power probe 3

 

[John Arrambidez]

So update I replaced the AGS and still same issue. So now has to be the cable somewhere I would think. I don’t see any where the wire is cut or messed up though.

You’re going to have to start opening the harness up. I’ve seen many of damaged wires in a harness that don’t show any signs of damage. This is where a multimeter and a wiring diagram come in very useful.

Ok so if you get this code it is not the shutters it is not the motor it is the wire and the pigtail. YES it took me this long to fix it inspection is this month. I have a brand new motor I bought in feb but was too cold to get the grill off in one piece.

The wire for the BUS had corroded off but you could not see it. I lucked out when I checked the positive lead with the power probe I got power and then I lost it so that wire was bad. When I pulled back the plastic loom found other wire was bad. Here is the part you need mopar discontinued it. Guy ships fast and is well protected in a huge bubble wrap.

How did you wire it. My truck only has 3 wires. This plug has 4!

You just match it to the old connector. Lots of connectors have empty spots.

So i just leave the new plugs 4th wire going no where?

The trucks OEM plug 3 wires. So I match up the plug and dont use the wore on the end, since thats the empty slot on the OEM?

Ya, just match the wire location to the connector that’s on the truck.

It was a stupid idea to begin with...

I have a CEL now. The reader says U11E9. How can I troubleshoot this? If the grill shutters cycle at startup, does this mean they're good? Is it the AGS or the active air dam?
