VUE FWD L4-2.4L (2008)
The scan tool communicates over the various busses on the vehicle. When a scan tool is installed on a vehicle, the scan tool will try to communicate with
every module that could be optioned into the vehicle. If an option is not installed on the vehicle, the scan tool will display No Comm for that options
control module. In order to avert misdiagnoses of No Communication with a specific module, Refer to Data Link References (See: Testing and
Inspection/Initial Inspection and Diagnostic Overview/Data Link References) for a list of modules, the busses they communicate with, and the RPO
codes for a specific module.
