I can only see 2 or 3 parameters when I connect to the vehicle or not all the parameters listed have values. Whats wrong?
Ensure that the All Parameters group is selected. The current parameter group can be changed by selecting the Choose Parameter Group button on the parameter grid screen. It’s possible the vehicle has more than one controller. Most Chrysler vehicles (Jeep is one exception) and Kia vehicles have more than controller. An engine controller and a transmission controller. When a vehicle has two or more controllers, the scan tool displays the Controller Selection screen immediately after connecting to the vehicle. Select the Controller that has the higher PID count to see the larger group of parameters. The Controller Selection screen can also be displayed via the menubar by selecting Vehicle/Select Controller. Most vehicles that connect with the VPW interface allow the packing of parameter data for faster information. Some do not. When this occurs, there are several parameters on the parameter grid that do not have values or the traces do not appear as they should on the charts for all param
