    I’ve always laughed because of how smooth my pat’s rear diff engagement is, “I’ve got this lil lever right here that makes this fun light pop up on my dash. Not really sure what else it does.”
    Problem with off-roading the partriot (besides the ground clearance), is the lack of low gearing. You don’t have enough torque to crawl, so you need to depend on momentum.
    Makes it a better all-around road car, but limits how much fun you are able to have with it on the weekend.

    • @shoveI
      @shoveI  8 місяців тому +2

      I've wished for a low range or a wider ratio transmission too - even a real limited slip differential at either end would help because the nature of the BLD traction control system is to cut your effective torque in half whenever it's in operation. Taking a load off the BLD would mean keeping the full (if very modest) torque more often. I think it's possible that a LSD from a Lancer EVO would fit in the RDU but I don't have the bandwidth or finances right now to experiment with that.

      The BLD system is a bit of a disappointment. I've used it to sink and bury myself more successfully than I've used it for self-recovery. Better off airing down, backing out of what got ya stuck, and then momentum is your friend.

    Awesome video. We just purchased a used Patriot and I wanted to see when you could engage/disengage 4WD. I had no idea it's really a front wheel drive, a plus, and engages the rear wheels for 4WD. Also had no idea it's sort of always in AWD/4WD at low speeds and heavy acceleration. You did a great job explaining it.
    I hope it works as well as we're anticipating. We live in a northern climate with fairly steep access to our place.

      Well my wife and I just bought a 2016 4x4 and idk about its AWD system, but I can confirm that when we popped it on 4x4 the other day while it was snowing, I had no issues. I was in slushy parking lots trying my hardest to break traction, even squirreling it left and right, and I couldn’t break it free.

    That's a way of doing 4wd/Awd i didn't know about.
    This is actually the first time i have heard if a vehicle being front wheel drive and engaging the rear wheels for 4wd. Front wheel drive generally tends to have better performance and steering control off-road. I like this idea.

      It's not entirely new for example Ford Tempo cars as early as 1987 optionally had something a little bit like this - not quite as refined. That probably wasn't the first it's just the earliest example I can think of right now. Despite its limitations in performance and heavy off road situations it's a completely appropriate system for this kind of car & I think it cashes all the checks it actually writes. More than can be said for some other specific Jeeps 🤣

      In my opinion they are supremely average with all the good and bad that accompanies that word. I see them everywhere, in fact typing this I'm in a parking lot across from one.. I know they sold a lot but there seems to still be a lot on the road, even 15 year old ones.

    Thanks for taking of your valuable time to make this video for us. Very helpful indeed. One question please, Is this system similar to the 4x4 in the smaller new jeep 2015, 2016 Renegades, or are these more rigorous for off-roading? Thanks again.

    • @shoveI
      @shoveI  Місяць тому

      The Renegades have a disconnect at both ends of the driveshaft instead of just the back - this slightly improves fuel efficiency and acceleration in 2wd mode. Otherwise the 4wd system behavior and mechanism are the same. Renegades replace the on/off "lever" that Patriots have instead with a mode selector but that changes throttle and transmission behavior much more than it changes 4wd programming.

    • @shoveI
      @shoveI  8 місяців тому +1

      I haven't installed a winch but I did make sure to have recovery points at both ends and I carry a hand powered winch and a tree strap when I go hiking or camping away from pavement. Patriots only came with recovery hooks from the factory if you got the "Freedom Drive II" package, and there's really nowhere else to hook a strap or hand winch.
      Mine didn't come with them so for the front I bought factory tow hooks and for the back I installed a trailer hitch. I'm not towing any trailers but a bike carrier fits nicely in it + it's a solid, safe place to pull from if I get stuck. The nice thing is Patriots are so light that a hand powered winch (sometimes called a come-along) moves it pretty easily and is a whole lot more affordable than a whole winch & the necessary bracketry, and it works from the front or the back instead of just the front.

      I really don't know enough about the intercompatibility of 2wd and 4wd control systems and wouldn't want to be the first to explore it either. These things are inexpensive enough that unless you got donors for free I can't imagine it would be cost effective to 4wd swap a 2wd one vs. just selling the 2wd one and buying a 4wd.
      It's similar to when people get V6 or 4cyl pony cars for $2500 and want to V8 swap them but they could just get a V8 in the same condition for $4k in the first place. Unless you've got cheap or free parts don't build what you can buy.

    The only difference I would add is if you have the Patriot with "Freedom Drive II" that it behaves much differently if you have it in "4wd" and then put it into the "L" position on the transmission.
    Per the manual:
    - Off-Road Features
    The following are key off-road features which are active
    when the system has the 4WD lock lever engaged and is
    in the Low Off-Road mode.
    • Hill Descent Braking
    Hill descent braking uses the
    vehicle braking system to provide a controlled descent
    down varying grades. This feature is only active when
    the system has the 4WD lock lever engaged and is in
    the Low Off-Road mode or reverse. Hill descent
    braking can be turned off by turning off ESP. The hill
    decent control speed varies between 4-6 mph (6-10
    km/h) forward, 3 mph (5 km/h) reverse.
    • Off-Road Brake Traction Control
    When conditions
    warrant, the vehicle braking system transfers torque
    from side to side. It does not control throttle input
    unlike normal traction control which is active in
    Normal Drive mode.
    • 19.1 Crawl Ratio -
    When the system has the 4WD lock
    lever engaged and is in the Low Off-Road mode, the
    CVT2L initially maintains the 19:1 crawl ratio before
    changing ratio. This low ratio is ideal for crawling over
    obstacles.
    • 4WD Lock Mode -
    4-wheel drive lock mode com-
    mands a higher torque to the rear wheels, for im-
    proved traction capability off-road. It also, turns on
    other system features in conjunction with Low Off-
    Road mode.
    Unique Engine Calibration
    - When the system has
    the 4WD lock lever engaged and is in the Low
    Off-Road mode or reverse, the engine calibration
    changes to run higher spark advance with premium
    fuel for optimum off-road performance. Your vehicle is
    equipped with an active spark knock system and can
    adjust the engine calibration for a varying range of fuel
    octane levels.

    • @shoveI
      @shoveI  9 місяців тому +1

      The systems are mechanically the same. FD-II equipped Patriots have a lower (numerically higher) final drive ratio and different software calibration to hold the numerically highest transmission ratio. All Patriots have the off road brake traction control - I demonstrate that in another video - and both 6F24 and manual Patriots can be held in first gear using driver controls. FD-II is more of a tuning difference than a material one.

      I'm certain it's possible to intercept the ECC solenoid control wires (the control unit is in the left side of the dashboard according to the FSM) - it might be necessary to include a dummy load when intercepting them to avoid a fault.
      I can not find it anymore but somewhere I read that the torque capacity of the ECC is 1800 ft-lbs when locked. I do not know if the electromagnet requires thermal relief while in operation (separate of the heat generated in clutch slip) .

      The first thing is to make sure it's 4wd in the first place, they sold these as front wheel drive only too. You can use an obd2 dongle with an application called JSCAN to monitor the 4x4 system, and of course one can always safely support the vehicle and get under it to inspect for damage. If there is a driveshaft and it turns with the front wheels you can focus on troubleshooting the rear drive unit.

      The 4wd system on a 2nd gen Compass is mechanically very similar to a 1st gen, with the addition of a clutch in the PTU so that the driveline connecting the front and rear is stationary under normal operation until slip occurs.
      Normal operation while in 2wd is front drive, the front axle is always 100% coupled to the transmission and then rear axle can never be driven faster than the front axle.

      @shoveI  11 місяців тому +1

      Low range is a nice feature but a traditional 4x4 to your definition, when shifted into 4H is not the same as an AWD vehicle. Some SUVs from the past had 5 position transfer cases with both 4H and AWD selections in the same car.
      In terms of driving dynamics and application those two things are very different and the distinction is an industry standard reflected on emblems and literature for the cars and trucks which feature them.
