This item is mainly used for odometer adjusting, audio decoding, airbag resetting, anti-theft code reading, and ECU memory programming. Update through Internet, nearly support all kinds of latest vehicles. Two keys to correct the CPU type odometers Read and adjust the internal data of CPU At present, most CPU are of encrypting type CPU for most latest vehicle models, such as Mercedes/Benz after 2001, new BMW series 7 and series 5 in 2002-2003, Renault, Citron (double CPU), and some Volvo, etc. Even some foreign odometer correction tools with price up to 10,000USD still cannot work with the new style BMW 7 series, Benz E series either. This technology belongs to the top technology in the world, the manufacturer of this item has already broken through it, and has reached the top level in the world. Get the digital coding algorithm of the odometer This is a very important factor. If this problem cannot be resolved, the mileage can only be adjusted with several regular distances, cannot be adjusted at any distance. Most of CPU correction tools in the market have not got the digital coding algorithm of the odometer. Therefore, their applications are limited. This item has get the digital coding algorithm of the odometer for most CPU for the latest vehicles. It can be widely used to correct the CPU type odometer at any distance. Worldwide advanced technology BMW 5/7ser/X5 since 2000 cluster adjusting directly, no need to replace M35080(memory) BMW E60 (5ser since 2004) CAS module adjusting BMW E65/E66 (7ser since 2002) CAS module adjusting Mercedes Benz W203/W220/W211 cluster and ignition module adjusting Mercedes Benz S/C/E class (2004-2005) cluster and ignition module adjusting Hyundai/Peugeot/Renault/Honda/Picasso(NEC CPU) cluster adjusting ***
