#SCANMASTER ELM V2 1 CODE#
Version 2.1 began to be released in 2014. We are talking about the Chinese version of the adapter ELM327. Adapters manufactured on the basis of the original Elmelectronics chip are very expensive for the average consumer (only version 2.1 chip costs $ 21). Unlike ELM327 v1.5 (v1.4), which are based on the “borrowed” firmware of the original ELM327 code reader, version 2.1 is a completely original development of the Chinese and has nothing in common with the original ELM327. These adapters were developed and tested, apparently, under Torque, Scanmaster, etc., with which they work satisfactorily.Īctually, why it does not work: firstly, it is not supported, or a number of AT-commands ELM327 are supported incorrectly. Secondly, in some places the adapter behaves just inadequately, for example, it does not return a response from the modules or partially returns it. How it looks to the user: the adapter finds the diagnostic program, but then either cannot connect to the car or identify it. Their differences lie in different microcontrollers and their firmware. Let’s start with the fact that you do not visually distinguish between two versions of the adapter.ĭifferences between ELM327 adapters version 1.5 and 2.1
