Audi J518 ELV Emulator, works with Xhorse VVDI PROG is designed for repairing Audi 6th-generation J518 ELV module of C6 Q7 A6. Here is the instruction of how to program 128 256 Audi EZS.
Part 1. Audi 9S12DG 128 EZS
1.Read and save original data (always backup data first)
2.If original EEPROM data file size is 2KB, then users need to send file for converting it to a 4KB file (Please send us our webstie order number and your data to use, factory will help to convert. )
3.Connect VVDI PROG to J518 Emulator, and write edited EEPROM file.
Note: Select J518(2010)(0L01Y) for 256 chip
Generally, users write only edited EEPROM data, writing FLASH is not required.
Part 2. Audi 9S12DG 256 EZS
Read and save original data, and write original data into J518 ELV Emulator.
MC9S12 Reflash Cable:
Red=VCC, black=GND, yellow=RST, purple=BKGD, green =XCLKS, White=CLK, black=GND-C
J518 module has 2 types: with/without a buzzer.
1)PCB with a buzzer
2)PCB without a buzzer
Solder as PCB prints, same to that with a buzzer.
Note: VVDI programming cable can connect J518 module to VVDI PROG via 20pin port without soldering.
When programming is done, better tested on vehicle instead of on bench.
To test on bench, check wires in 20pin port before any test, or it may damage emulator chip.
Cable in PIN10 (Red) should be in PIN20(Blue)
Alright, that’s how to program Audi J518 128/256 EZS by J518 ELV Emulator.
