I purchased a MaxiCOM MK808S which i used to perform active test on my AC compressor clutch and it worked. However, i returned it for another for known reason and tried to perform the same test using it, but it says the function is not supported. I tried from different angles, but it failed. This is 2011 Sedan Nissan Altima S.
I just used it to program an fob key for the same Nissan and it worked. When programming the key, it deleted all old keys and made me reprogram both new and old keys as new. The two keys are working, but most of the functions are no longer supported.
Could the new key be the reason and what must i do? Please advise.
