Communication between Gear ECU and Lexia Diag
Aug 26, 2017 (2 years ago)
The Lexia 3 Diag could not communicate with the gear ECU. During Diag, I always get the massage: "ECU not recognized" when it gets to the gear.

"Lexia" is Citroen,
Peugeot Planet is for pugs,
Shouldn't make a difference but who knows?
