(Solved) Kess v2 error “External exception EEFFACE “

I replaced chip and reset tokens, then get connection error “External exception EEFFACE” as following picture shows.


Try follow steps:

1.If you connect to internet with this clone tool,or make online update .The interface is destroy/broken

1.–Buy a new NPX chip with 60 tokens inside. Desolder the old NPX and change it with new.It cost 14-20USD, some users call this chip as CPU Repair Chip. Note: NPX is out of stock in some sites now, because the newest KESS V2 need not replace NPX, the NPX is preinstalled in the machine .


2.–or you have to weld a connector on backside of interface ,and plug the J-link programmer.
You can reset the Kess v2 to virgin. obd2tool.com is available with J-link V8, cost about 20USD, Note: the newest KESS V2 V2.06 is packed with J-link V8 programmer, no need buy additional one.

Details about j-link v8 solve ECU Programming Tool Kess V2 master tokens limited problem:
Step 1. Buy one LPC2478 chip to replace the original one for KESS V2 master.

Step 2. Prepare for a LINK J-LINK V8 ARM USB-JTAG Adapter Emulator.

Step 3: weld a connector on backside of interface.

Step 4: plug the J-link programmer


Also you can watch video in kess v2 master package to program the chip.
