EVIC - "4WD shift in progress"
 
Okay, this is likely a lame topic but I couldn't find any documentation in the manual or via Googling.

From time to time, when I start my 2014 WK2 (QuadraDrive II) the EVIC will display a "4WD shift in progress" message for several seconds. I can't reliably reproduce it, and the message doesn't seem intuitive.

This only happens when I'm parked and starting the vehicle. I haven't even touched the shifter yet when this message is displayed.

Anyone have an explanation?

I say have a camera ready and document with pictures and take it to the dealer. That's how I got them to look into my active cruise control issue that left no error messages yet disabled itself every 10 minutes.

I suppose I can give that a try. I was hoping this was just an innocuous thing that everyone has seen and that someone could explain.

Mine does the same only for a brief second while starting. I think it's just part of the EVIC's diagnostic procedure.

I saw something that sounds like the same thing on mine this weekend.

I'm Qudra Trac II.

I dunno

Could be this, read the symptoms part: http://www.wk2jeeps.com/tsb/tsb_wk2_2100614.pdf

Thanks for the suggestion; people should definitely check that out. I'm a December build, though. I do plan to have this one applied soon, however:

Back on topic, this is just kind of an odd message for an AWD vehicle to be displaying, especially when I haven't changed the drive mode (it's set to normal continuously).

I have no reason to believe it is a sign of trouble; I was just hoping someone had an explanation. It's nice to see that I'm not alone, though.

Mine started displaying that message today each time that I start the engine. It's a '14 Overland, April '14 build. I know that the "auto 4wd" kicked in yesterday as it was raining, and it seems like it doesn't know how to disengage the 4wd. It's not an empty message either, it's actually engaging the 4wd. I can tell when taking corners slowly. Don't really know what to do at this point.

If you have a 4WD WK2, 4WD (high) is always engaged.

FOUR-WHEEL DRIVE OPERATION

Quadra-Trac I® Operating Instructions/
Precautions – If Equipped

The Quadra-Trac I® is a single-speed (HI range only)
transfer case, which provides convenient full-time fourwheel
drive. No driver interaction is required. The Brake
Traction Control (BTC) System, which combines standard
ABS and Traction Control, provides resistance to any
wheel that is slipping to allow additional torque transfer
to wheels with traction.
NOTE: The Quadra-Trac I® system is not appropriate
for conditions where 4WD LOW range is recommended.
Refer to “Off-Road Driving Tips” in “Starting and Operating”
for further information.

Quadra-Trac II® Operating Instructions/
Precautions – If Equipped

The Quadra-Trac II® transfer case is fully automatic in the
normal driving 4WD AUTO mode. The Quadra-Trac II®
transfer case provides three mode positions:
• 4WD HI
• NEUTRAL
• 4WD LOW
This transfer case is fully automatic in the 4WD HI mode.
When additional traction is required, the 4WD LOW
position can be used to lock the front and rear driveshafts
together and force the front and rear wheels to rotate at
the same speed. The 4WD LOW position is intended for
loose, slippery road surfaces only. Driving in the 4WD
LOW position on dry, hard-surfaced roads may cause
increased tire wear and damage to driveline components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 4WD HI
position at a given road speed. Take care not to overspeed
the engine and do not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
cause damage to the transfer case.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.

Re: EVIC - "4WD shift in progress"
 
That's what I thought as well, but up until this point, I was never able to tell that I was in 4WD, if that makes sense. Now, when making a slow turn, such as in a parking lot, there is a "binding" feeling, the steering gets tight, and it takes more throttle to get through the turn. It's been completely smooth up until this message started appearing today.
