I am want that scanner to check the codes of automatic transmission. I went to honda 3s dealership for checking transmission through computerized way.
They connected the scanner to ecu- all data was able to see at computer, no dtc, all PGMFI parameters are according to factory values but they click the AT option for checking the faulty codes for automatic transmission, the scanner is not connected to automatic portion to check the faulty codes. They said connection is not establish and hence we couldn't able to see the any faulty code.
That's why I need that tool also I am planning to upgrade the car to some latest model.
Can you tell me why their scanner is not connect to AT portion?
