  • I have a 2020 f350 with bliss in the taillights that is throwing the Blld6:15-ab code in the SODL/SODR modules. In
    Forscan, I have reprogramed the modules with as built data including the vin number. When I look at the configuration of the modules after programing they have a different vin number then what I just programed in. I keep getting the cross traffic alerts and side detection alerts on my display. When i turn on the ignition, both led's in the mirrors light up and then go out, indicating the self test shows it is working. Any advice?

    • B11D6 on the Super Duty usually relates to the BLIS indicator circuit (the LED in the mirror) or the way the side detection modules are communicating with the rest of the network. Since you’re seeing it in both SODL and SODR, it’s more likely a configuration or network issue than two hardware failures at the same time.

      The fact that the mirror LEDs come on during the ignition self-test is a good sign. That usually means the LEDs and basic wiring are working. The warning messages you’re getting are more likely related to how the modules are configured or what they’re seeing from the radar sensors.

      A few things stand out from what you described:

      First, the VIN changing after programming is something people see occasionally with FORScan. The SOD modules don’t always store the VIN the same way other modules do, and sometimes they will display a default or previously stored VIN even after programming. That alone doesn’t necessarily mean the programming failed.

      Second, if the as-built data doesn’t match the vehicle configuration, the modules will constantly flag faults. This can happen if:
      • The truck originally didn’t have BLIS and it was added later
      • A radar module was replaced with one from another vehicle
      • The as-built data was pulled from the wrong VIN
      • The truck has a factory tow package or aftermarket trailer wiring affecting the system

      On these trucks, the BLIS system also depends on proper radar alignment and configuration. If the radar sensors in the rear corners were removed, replaced, or the bumper was repaired, the modules can set faults even though the LEDs pass the self-test.

      What I would check next:

      • Verify the as-built data from Ford’s Motorcraft service site using your VIN and compare it line-by-line with what is in SODL and SODR.
      • Check the radar sensor connectors and mounting brackets behind the rear bumper. If the sensors are slightly misaligned, the system will complain.
      • Make sure the truck’s configuration actually includes BLIS with cross-traffic and the correct mirror type.
      • Perform a module reset and network scan after programming.

      If the hardware self-test passes and the radar sensors are mounted correctly, most of the time this ends up being a configuration mismatch rather than a failed module.

      The key is making sure the SOD modules, BCM, and IPC all agree on the vehicle configuration. Once the configuration matches the truck’s actual equipment, the alerts usually disappear.
