Xhorse Multi Prog Repair BMW G12 Tail Light Data

On this BMW G12, the right tail light was completely black. The fault was in the tail light data, so instead of replacing the lamp, I opened the unit and repaired the MCU data with the Xhorse Muti-Prog Programmer.

 

Remove the Tail Light

1. Pry off the side trim beside the tail light. Remove the lower tailgate trim as well. There are two hidden screws inside; the rest is held by clips.
2. Remove the six screws inside the light bar and pull the light bar slightly outward.
3. Remove the two screws behind the tail light. The complete tail light assembly can now be removed.

Open the Housing &Remove the PCB

1. This lamp had already been opened before, so I could pry it apart along the old sealant edge. On an untouched lamp, the rear cover would need to be cut along the original factory sealant line.
2. Remove the housing screw. Push the two PCB clips outward and slide the PCB out.
3. Disconnect the row of connectors from the PCB.

Wire the PCB and Flash the MCU

1. Solder the green wire and yellow wire to the specified test points.
2. Wire the five programming-port pins: brown to the top-row first pin, orange to the bottom-row first pin, black GND to the top-row second pin, red VCC to the bottom-row second pin, and blue to the top-row third pin.
3. Connect the harness to the Xhorse Muti Prog and open the programming software. Select the R7F701024 MCU protocol.
4. Read C-FLASH first and save the original corrupted data. Read D-FLASH next and save that file as well. Keep both original files backed up before writing anything.
5. Select C-FLASH, open the repaired C-FLASH file, and click Write. Confirm the operation. Do the same with D-FLASH using the repaired D-FLASH file.

Reassemble and Test

1. Once both files are written, unplug the programmer and remove all soldered wires from the PCB.
2. Reconnect the row of connectors and slide the PCB back into the housing. Lock both side clips in place, refit the rear cover, and tighten the screw.
3. Install the tail light on the vehicle and reconnect the tail light connector.

 

The tail light is back on. Repair completed successfully.

Xhorse Red PCB Toyota Remote Write Error Solution

If you work with Toyota smart keys and remote generation, you may have recently noticed a significant change in the hardware being shipped by Xhorse. The new stock of XKTO series Toyota remotes (XKTO24EN, XKTO25EN, XKTO22EN etc.) has arrived with a Red PCB, replacing the previous Green PCB versions.

Because many users are utilizing these remotes to build modified flip keys, there has been some confusion regarding the cloning and generation process. If you are encountering a “Write Error” while trying to generate a Red PCB Toyota remote, this guide will provide the simple solution.

Green PCB vs. Red PCB: What’s the Difference?

Up until recently, the Toyota remotes used a Green PCB. The method for generating and cloning these older versions was different from the new stock. The new Red PCB remotes require a slightly different approach, particularly when it comes to how the device connects to the remote during the writing process.

The Problem: The “Write Error”

When attempting to generate a Toyota remote with a Red PCB via a wired connection, choose normal generation. many users are running into a “Write Error.”

It is important to note that this error does not appear on every single remote, but it is a common occurrence with the new Red PCB stock. If you see this error on your device (such as the VVDI Mini Key Tool), do not panic. There is a very simple workaround.

The Solution: How to Generate the Red PCB Remote

If you encounter a write error while using the wired method, follow these steps to successfully generate your remote:

Remove the Wired Connection: Disconnect the remote from the programming cable.

Insert a Battery: Place a battery into the remote. The remote needs power to communicate wirelessly.

Select Wireless Generation: On your device, exit the current process and navigate to the Wireless generation Gen2 option.

Press a Button: After initiating the wireless generation, press any button (Lock or Unlock) on the remote once to wake it up and establish the connection.

Wait for Completion: The data writing process will begin. You will see the wireless generation progress on the screen without any wires attached. Once it says “Generate OK,” the process is complete.

Conclusion

The new Xhorse Toyota Red PCB remotes offer both wired and battery-powered generation options. However, if the wired method fails and gives you a write error, simply switch to the wireless method using a battery. This procedure ensures that you can complete your Toyota Type remote generation and modified flip key builds without any hassle.

We hope this guide helps clear up any confusion regarding the new Red PCB stock!
