Yes just manually bypass the obd two portion like you did before you got the CANupdated adap. Until you can find a solution to why its not functioning . Make sure it is firmly connected to Base. Also like Mark said, reboot ,and possible hard reboot.
Yeah, Like Friendfx said, they are CAN vehicles. Sometimes if a car does not read on RPM I do a reset on the moduel itself. I use a paper clip and hit the reset button. Most of the time it will solve many of my RPM problems and saves me from aborting too many tests.
Make sure you unplug it from the vehicle first, before you reset the moduel.
dose anyone have problems with dodge rams 1996-2000 they are not can but i pre screen all my cars before they come in i cant get the obd2 system to communicate with the smog machine or hand held scan tool but when it comes to rpm it picks up rpm and passes functional check ive done atleast 10 in the last month and every single one had this problem
