Are OBD2 ports always powered?
The OBDII port is always powered up, even when the car is off. The Scangauge II turns off parts of itself when it doesn’t detect impulses on the system for a number of seconds (I’m too lazy to look up the actual number).
Why is my OBD2 not getting power?
Check your fuses. Look for the one labeled “accessory”, “ACC”, “CIG”, etc. on the label on the fusebox lid. If you aren’t getting power at the port (easy to test with your multimeter), the fuse is likely the issue. If you ARE getting power, then options are: Break in the harness between the OBD2 connector and the ECU.
