Read 2024 Hyundai RH850 Airbag Module by Xhorse VVDI Prog

 Today we received an 2024 Hyundai airbag module. We’re gonna reset it with Xhorse VVDI PROG on bench. Before that, we should read and save its DFLASH & CFLASH of the module.

First, we’ll do its connection.

Connect VVDI PROG& airbag module according to wiring diagram.

Second, Open VVDI PROG software.

Type: 2-MCU

Brand: RENESAS-RH850

Chip: R7F701042

Read DFLASH…

The module is working, the frequency has been matched now.

Read DFLASH success.

Save DFLASH data file.

Read CFLASH…

Read CFLASH success.

Save CFLASH data file.

VVDI Prog and VVDI2 2010 Ford Transit All Keys Lost

 2010 Ford Transit Mk7 all keys lost and active Cat1 factory alarm.

Key learning cannot be carried out by normal OBD operation with alarm active as key learning by OBD is blocked.

Removed BCM, read key data (chip MC9S12DG256) directly from the module using xhorse vvdi prog on the bench, added a new key on the bench with xhorse vvdi2, installed BCM back to the van, switch ignition on with registered key and alarm is deactivated.
Now we can erase all keys and add new all by OBD.

Xhorse VVDI Prog BMW FRM Lost OBD Communication?

 Problem:

In this E series FRM XDT256 model, after making a copy of the EEPROM and FLASH with xhorse vvdi prog, I have a ‘Lost OBD communication’ error. Any solution?

Solution:

FRM Repair Method:

Remove FRM, check data with VVDI Prog, if all data are blank (FF), then write data to the MCU.

First disassemble the FRM and use VVDI PROG to check its data. If the data is empty (FF), then you only need to re-write data into it.

Some cars can be repaired directly after writing the data, If there is a deviation, for example, if the vehicle model is similar but the data is different, then you will need to perform FRM coding with universal scanners (i.e Launch X431).
