Lexia 3 Fails To Communicate And Can’t Read Ecu Issue

Lexia 3 with Diagbox V7.57(item SP08-C) is the best lexia diagnose tool among all the lexia 3 we sell on the shop. It has original 921815C chips inside, and it is also fully compatible with Peugeot 307/C5.

Recently, we got some customers feedback, They meet problems with:

  1. There is no communication between lexia 3 device and computer.
  2. Have tried on many cars, but it can’t read the ECU.
  3. It can be detected by the computer at the beginning. But it cannot be detected anymore after a while.

If you also meet the problems as mentioned, there is a problem with the chip which is circled (see following pic), pls replace a new chip for it.


Any help, pls do not hesitate to contact our customer service
