  1. Changed battery on 2019 Ranger. Battery light on and windows don’t work

    Yes - Check the 225-Amp Fuse - not just a visual but check for voltage on both sides or pull it off and verify its intact. Plus check the (cable) end connection from 225 Amp Fuse down to the (Alternator) and the (Connector - Lin Bus) on the Alternator for security Plus also ensure Connector (B)...
  2. Code P0446 EVAP System Check Engine Light

    It may be possible to just lower the tank (enough) for access But I would try the procedure above first, install the (truck supplied) funnel and read the FTP PID, with a scan tool - (check actual sensor reading) Key On - Engine Off With the funnel installed - its looking for (Atmospheric)...
  3. Another Rear Leaf Spring Thread - Extreme edition

    I think I have some pics in the other thread - (Snap-Shots) from a random video showing how they are made - at a point in the video it shows the (Die Press) that holds the plate as its rolled (creating the eyelet) - so far it looks like they are all breaking at the exact same spot (and its where...
  4. Dashcam Power Options

    Does your mirror - have Auto-Dim (It will have a small dark circle) embedded into the mirror and it will not have the old school lever at the bottom (where it flips the mirror) upwards (blinding lights) position - this is the auto dim power feed and power is shared with the (Power Fold) button...
  5. Ford Ranger IV 2020 - No OBD connection

    Then I suspect they may all be grounds: PCM - Disconnected Each Pin to - Case Each Pin to - Ground Pins on the connector I suspect you will find continuity
  6. Lane assist

    Yes -its one of those (buttons) that's kind of hidden - I had the display on the screen and wanted it off - spent some time going through the menu - no change - Finally did the proper thing and actually go back through my brief skim of the owner's manual and then saw the button. I had this...
  7. Returning reverse camera to Ranger

    Its hard to tell for sure - if they left the (OEM) wiring. You are looking for at least with the US Ranger C411 - its a 8 cavity (7-Wires) if you have a (Remote - Lock/Unlock) tailgate The Tailgate itself had the internal camera and lock wiring - it ran down to an opening in the tailgate and it...
  8. Lane assist

    You can initialize it with Forscan - Run New Lin initialization
  9. Ford Ranger IV 2020 - No OBD connection

    I dug deeper into the board and i think that those pins are actually power and ground feeds for the board - I can see 4 sets in the pic. And I think this set may be the (feed for the 5-Volt) VREF circuit (step down regulation) as well as the internal 3.3 volts for the processor power as this...
  10. Ford Ranger IV 2020 - No OBD connection

    At this point: I would check - with PB Start (Attempt) - (Helper Required) 1. Check the Starter Relay - Coil - Power and Ground - are they being applied 2. HS1 - Can Bus activity (Does it fluctuate?) when the start signal is being applied - it should fluct slightly around the 2.5 volts...
  11. Ford Ranger IV 2020 - No OBD connection

    We in the US - use a (Single Use) Vehicle and have a subscription base - Month, Yearly etc They run about $60.00 a year (USD) - Most Popular are Alldata DIY and Mitchel DIY Some also buy the manual outright - Helm, which actually publishes the Ford Manuals or find copies (PDF) on Ebay etc - the...
  12. Ford Ranger IV 2020 - No OBD connection

    Basically-Back probe 100- 102- 103 , is the PCM Relay closing? Are all the PCM Grounds - Good? Can the PCM relay (coil) get a ground to close and do the PCM power feeds in 100-102-103 have a path to ground.
  13. Ford Ranger IV 2020 - No OBD connection

    Most of what I am giving you - since I cannot see the ROW Ranger diagrams, you are going to need to find where the specific (pin) is located. The standard function should be the same, but the pinouts are going to be different as our PCM (Incorporates) the TCU (Transmission Control Unit) into a...
  14. Ford Ranger IV 2020 - No OBD connection

    Yours should be similar as this is for a 2.3 Ranger We need to pinpoint - is the BCM or PCM - preventing the No Start Issue We know that the switch is getting power (flashing) but we do not know if the BCM and PCM are communicating together that a start request or ISP-R (Ignition Switch...
  15. Ford Ranger IV 2020 - No OBD connection

    If you have 4WD a quick test: Can you switch from 2 High to 4 Hi or Lo If yes the PCM Power Relay is closing. Key On - Test Also even if you do not have 4WD , check fuse 19 in the BJB with key on (PSCM) fuse feed- if power is here - the Run Start Relay is closing. This will give some direction...
  16. Ford Ranger IV 2020 - No OBD connection

    for me at this point I think the PCM is not powering up Unless you are able to read codes or connect and the scan tool read the VIN from the PCM I would also get the OBD-EX adaptor - this has proven to work without issues with Forscan, this way you will have a better chance of getting...
  17. Ford Ranger IV 2020 - No OBD connection

    The (AC Outlet) is from the DC/AC - the DC/DC is a separate module, both the BCM and DCDC sit on HS1 So we know that the DCDC is pushing power out as you have voltage on Pin 24 (GWM) that's is what provides it. (VBAT) So if you look at the wiring diagram you will also see (VPWR) - this uses...
  18. Ford Ranger IV 2020 - No OBD connection

    GWM - showing the transceivers - that the wiring diagram leaves out, i knew it had the terminating resistors inside, but did not realized or pay attention to the detail that there was an extra set of (resistors) inside for Diag 1 and Diag 2
  19. Ford Ranger IV 2020 - No OBD connection

    So to dumb it down: Diag 1 = HS1 (Network) - the GWM internally connects to the HS1 Can Bus Diag 2 = HS2 - HS3 -HS4 and the MS Can Busses - also GWM internally connects to those busses Pins 6 & 14 - Check Diag 1 Pins 3 & 11 - Check Diag 2 This only checks the com from the GWM to the DLC
