A little light reading...
There is no indication to the driver of the vehicle when a fault with the active grille shutter system is present or a active grille shutter DTC is set in the PCM .
Does this just mean there is no indicator on the dashboard or that we can't see the code with a reader?
Thanks Pup...I read all you wrote. I can find no fuse directly to it and for the time being I haven't seen any other position other than wide open. Like I originally said the truck takes longer to heat up than it did when purchased 5 months ago; so I'm wondering why when I found the shutters. If they are open its fine. The truck still heats up to 195-198 but just takes longer than when new. At the next service I'll mention it and see what happens. A tech may have a test they can do. Thanks for your input....
There's probably nothing wrong. If you read the description of the sequence of operations, the system goes thru a self-check at each startup. If something wasn't working right it would set a trouble code and light the check engine light. I guess if you want to be really sure you could check for any codes. Everyone has at least a cheap code reader, right?
msg and pup, cycled it with the remote start and it recycled correctly. As for using the remote, the truck seems to have its own mind on what to do with inside temp so I'll need to watch the AC clutch on a first start start. I leave the complete HVAC off along with the radio when I shut off the truck; but using the remote start and getting in after a few minutes and touching the start button to energize the dash the HVAC will be on doing what it thinks I want. I've had the cold on my seat on, the heat on, and it off. I'm guessing since I used the remote it will respond to the outside temp versus the inside temp and correct it all.
Geez I love the heater in my 56 Victoria. Slide the temp to high, move the lever to heat or defrost, and select hi-low for the fan. AC is open the windows, pull the ***** for air at your feet and adjust the wind wings (remember those) to about 45*....
Well if you read the manual, You won't hurt anything leaving the heat or AC on when you turn it off. whatever it was set on last will contorl what happens when you remote start it. Yes if you have the climate setting turned on in truck settings it will depending on outside AND inside temps control what turns on when you remote start. It will automatically start warming the seats and cab air or cool as needed.
Under the remote start menu you have the choice of having the system use the last setting when you turned the truck off or the system default settings. For the default setting choice the internal temperature is 72 degrees and the system will warm or cool as needed. In addition, if the outside temperature is below about 37 degrees it will bring on the seat heaters, the steering wheel heater (if you have it) and the mirror and rear window heaters. Leaving it in the default setting choice works well for me.
TJ, I've read the book and on a vacation over the holidays I would turn the truck off with the settings I wanted in the morning. Most of the mornings were really cold and leaving the heated seats in the on position and heater fan on vents and floor were very handy. The reason I leave everything off is habit and maybe getting use to what the truck sees and I don't feel is my problem.
the reason for the tread is the shutters. For me after start up and cycle when the engine is cold the damn things should be shut so the engine will reach operating temp quicker. To me it did that in its first few months and now takes longer. That's it...
Active Grille Shutter The active grille shutter actuator positions the active grille shutters based on commands from the PCM . The active grille shutter moves 90 degrees from fully closed to fully open and, based on the position commanded by the PCM , is set in 1 of 16 positions (approximately 6 degrees between positions).During normal operation, the active grille shutter may be partially to fully open when the engine is off depending on the ambient temperature. After an engine starting event, a self-calibration of the active grille shutter system occurs which typically takes 15-20 seconds. The active grille shutter system performs the calibration sequence by detecting the end positions, open and closed. The calibration sequence can begin in either direction, open or closed, and continues until it is successful or a fault is sensed. A long pause may occur between the 2 portions (open/close) of the calibration sequence. If certain faults are present (shutter blocked or actuator error), a re-calibration is initiated in an attempt to resolve the problem. If the problem is not resolved after a calibrated number of re-calibration attempts (usually 3 or 4), a timer starts and sets a DTC when the timer reaches a predetermined limit.NOTE: If equipped with 2.7L and 3.5L GTDI, the upper and lower active grille shutter actuators operate independently from each other and transmit/receive unique commands to/from the PCM . Each active grille shutter actuator reports unique Diagnostic Trouble Codes (DTCs). The PCM communicates the desired position (open, closed or in between) of the active grille shutter systems. The upper active grille shutter control is based on various PCM inputs (vehicle speed, coolant temperature, ambient temperature, A/C system pressure, etc.). If equipped, the lower active grille shutter control is dedicated to managing charge air temperature into the turbocharger, and is based on PCM inputs such as vehicle speed, turbo charge pressure, ambient temperature, charge air temperature, etc...The PCM communicates to the active grille shutter actuator(s) via a LIN . The LIN supports bi-directional communication between the active grille shutter actuator(s) and PCM , allowing the active grille shutter actuator(s) to communicate position and fault information to the PCM .The PCM sets active grille shutter Diagnostic Trouble Codes (DTCs) when the fault information is communicated by the active grille shutter actuator for a predetermined amount of time. Any failures of the LIN for over 10 seconds continuously results in the active grille shutter actuator positioning the active grille shutter fully open. There is no indication to the driver of the vehicle when a fault with the active grille shutter system is present or a active grille shutter DTC is set in the PCM .
The lower grill shutter on my 2016 F150 stayed in the closed position and I am being told that because of that, the trucks temp rose rapidly which caused a domino effect.. turbo fittings sprung a leak, oil & coolant leak, just to name a few... and all within a matter of hours.
No service light came on until the damage was significant. And also on a truck that has been serviced on time by the dealership and has had all needed services based on miles... I have bragged how my 2016 truck has been in perfect condition with no issues.. ever.
Anyone ever heard of this happening all of a sudden with no indication there was an issue??
My lifetime power train warranty claim is being denied and they are saying all of the damage was because of the grill shutter staying shut.
So they say there was a faulty part (grille shutters/motor/sensor) but won't cover the damages? I think I'd be going up the chain on this one.
@scott91370
The dealership didn’t say why it stayed closed but I agree with you about going up the chain..
I’ll admit that I’m not real knowledgeable about mechanics, and everything that is tied to or considered being part of the power train of a truck, which is what prompted me to start researching the internet to see if I could find anything on this particular issue, and that’s when I came across this forum.
