    I just bought AlfaOBD and obdlink mx+. I'm trying setup global window down. When I select the option from body computer - car configuration change - global windows down, the options are Absent/present instead of disable/enable. What am I doing wrong?

    I tried settingit to present and my dash lit up like a Christmas tree. I switched back to absent and the dash was still throwing alerts and odometer flashing. I had to do a proxy alignment several times to fix it. Any ideas? Do I need the blue cable with OBDlink? I have the gray one on order.

    OBDLink MX+ is probably the best one available. Good choice.

    What year is your renegade?

    2018+ will require a security gateway module bypass.

    A security gateway bypass module (infotainment.com is where I got mine).
    Or a FCA Chrysler -12+8 Adapter cable (Amazon is where I got mine).

    SGMM.jpg SGMC.jpg

    If you are using the security gateway bypass module, you will find the Security Gateway module (SGM), unplug the two connectors and replace the SGM with the security gateway bypass module, then plug your OBDLink in to the normal OBD connector for the Renegade.

    If you are using the security gateway bypass Cable, you will find the SGM, unplug the two connectors from the SGM and plug those connectors that went to the SGM in to the security gateway bypass Cable, then plug your OBDLink in to OBD port of the FCA Chrysler -12+8 Adapter cable (NOT the normal OBD port for the Renegade).

    NOTE: There are two modules that have the same exact connector pin-count. 1 is the Security Gateway Module, the other goes the the HVAC system.
    SGM for the Renegade is located near the steering column support bracket.

    Open the AlfaOBD app,
    connect to the OBDLink MX+,
    select your vehicle (Renegade BU),
    select the module you wish to access,
    select the model year type of the module you wish to access.

    at the next screen, Connect to the module.

    ** good habit, go to the battery icon, Read System ID, and then Read System status and save to your Google Drive. That way you have a reference to use should you make a change and want to put it back.
    THIS IS NOT A BACK UP. it is only the information of that module before you make a change, so that you can put it back the way it was should you need to.

    go to the open hood,
    select Car Configuration Change,
    go to where yo want to write you change,
    write or select your new value...

    Good habit. Make only 1 change at a time. disconnect and close out AlfaOBD, turn off the key and wait 5 to 10 minutes for the system to update before making your next change/modification.

    Here is a great reference for AlfaOBD. It it a Ram forum, but the information is useful.

    ***another note... if you are using the Security Gateway Bypass Module AND the OBDLink MX+, no other cables are required (blue cable, etc.).

    **** Oh, and another note...
    I keep the Security Gateway Bypass Module connected all of the time. If I want to make a modification or need to clear DTC's, all I have to do is plug in the OBDLink, make my modification, read and/or clear codes. BUT!!! if you ever have to take your Renegade to the dealer, make sure to remove the Security Gateway Bypass Module and reconnect the Security Gateway Module.

    The dealer diagnostic computer will disable the Security Gateway Module before it can do any work. If you leave the Security Gateway Bypass Module installed, the dealer's scan tool will fail to connect... and any warranty on the vehicles modules will be voided (all 40+ of them).

    So the gray cable seems to be working. I was able to set set the high beam fog light dropout and run the proxy alignment. The fog lights work with high beams on now.

    For some reason global windows down isn’t working. I changed the setting to present and ran a proxy alignment. It’s been at least a week and they aren’t rolling down when I hit unlock-unlock(hold) on the key fob. I checked to make sure the body control module took the change. It still is set to present. I ran another proxy alignment and it says everything is correct.

    Any ideas?

    I read once that the global windows down doesn't work on all vehicles.

    Looks like I might be one of the unlucky ones. What features do you have enabled? I was thinking about getting some headlight revolution vr4 headlight bulbs. I saw there are a bunch of led options in the bcu. Can AlfaOBD do the led switch or will I still need the pwm module?

    I am not sure what the pwm module is.

    If you have a 2018 or newer Renegade, you will need the Security Gateway Module (SGM) Bypass or the 12+8 cable for any modifications to take effect regardless of the software used to make the changes/modifications.

    If you are upgrading to LEDs, the changes can be made in the BCM, and resisters will not be required for the LEDs to work properly.

    PWM is the pulse width modulation module. From what headlight revolution told me, the renegades pulse the lights on and off to see if they are working. They sale a module that plugs between your leds and the headlight harness to keep your lights from flickering.

    I have a 2016 Trailhawk, so luckily, there is no SGM. I can connect to most of the modules with the OBDLink MX+ (It doesn’t require the additional blue cable). I also bought the extra gray cable so I can connect to the other modules. I know this is different from people with the SGM.

    I don’t see a setting for led headlights in the BCM. I saw an option for headlights and the options are type 1-4. Not sure if this is where I need to be. There’s also a setting for xenon headlights. I’ve read in the Dodge Ram forums, I can enable xenon and this disables the pulse width module. They said it should work for leds, because it provides a constant current instead of pulse. That’s for ram though, not sure about the renegades.

    @IDoMy0wnRacing, I've also just bought the AlfaOBD software, with OBDlink MX+ scanner and the FCA Chrysler -12+8 security gateway bypass cable, and this is the first clear and most useful information I've found about its connection in the whole Internet for days! thanks a lot!!!

    Recently I've installed the full lead headlights in my Renegade MY2020, so I need to make some configurations in the computer to allow the high+low beam, and to leave fixed the DRL lights for the led halos (avoiding them to go out when blinkers are on). By chance, do you know which are the Car configuration options I should change for all these?

    From your second post, with my scanner + the bypass cable I understand I don't need any other extra conector (as the grey wire), do I?

    Thanks again in advance.

    Mauro

    I believe the area that you are looking for is:
    Body Control Module>
    Car configuration change>
    DRL Turn Light Strategy/DRL dropout

    The FCA Chrysler -12+8 security gateway bypass cable is the only cable that you will need.

    Thanks a lot Ed!

    And for allowing the high+low beams in the new full led headlights, do you know if there is another option to change? Maybe someone related with "xenon" as I read in some italian forum.

    Mauro.

    Xenon is your High Intensity Discharge (HID) headlights, this is where you would choose between HID and incandescent (conventional headlights).

    I cannot find an option for LEDs for the headlights.

    Great, I'll look for that option. It should be also in "Car configuration" section, shouldn't it?

    Thanks for all your help!!!

    Hi Ed!

    The 3 changes through AlfaOBD you suggested work perfectly, my led headlights are working just as they should now.

    The only problem is that now I'm getting this fault related with the power stearing in the screen. Do you know why is caused or how can I clear it? Is posible with any AlfaOBD option?

    Thanks in advance

    Have you tried going to the Steering Module and tried clearing the code from there?

    AlfaOBD is a great tool. One of its shortcomings is that codes have to be checked and cleared from their respective module.

    OBD JScan is another great tool. one of my favorite options is code clearing.
    When you perform an Advanced Scan, it checks all of the modules for codes.

    When you clear the codes, it clears the code in all of the modules and then performs another check to ensure that you don't have any remaining faults.

    Modules and codes can also be checked and cleared individually.

    You can find JScan from here.

    I'll try to clear the fault from the Stearing module, that's a good idea!

    It said to use the grey adapter but I've been conecting the MX+ to the SGW with the 12+8 cable. For this other module should I connect it to the OBD with the grey cable instead, or I can continue with the SGW?

    I cheked JScan but doesn't have Renegade included :(

    Thanks again!

    The MX+ with the 12+8 cable will work.

    with the 12+8 cable you shouldn't need any of the other cables.

    Hi Ed!

    I still couldn't clear the fault

    I'd realiced that I didn't make the Proxy Aligment process after changing the two Car configuration options for the new full led headlights. Should I do that? Could the fault be related with ommiting that?

    Thanks as always for your big help
