Subaru Problems? Ask a Mechanic for Answers ASAP
Replacing the battery very well may have reset the tire pressure system. Driving the vehicle may not be enough to reset the system. If the light is still on after the drive cycle, then the system will need to be reset. This will require the use of a scan-tool that can interact with the monitoring system.
If your OBD II tool is only a "code reader" then, no. The scan-tool needed would need to interact with the system. There would be a menu option for it on the main screen of the scan tool.
