It's likely an ELM327 device, and if you can send commands directly through an "ELM terminal" type app, send ATRV and see what the voltage is at the OBD-II port, and compare that to what you're seeing in the data stream from the PCM. Im just wondering if it could be a bad earth? Also just noticed this earlier, when I let it stay at idle eventually the SRS light and ABS light come on very dim until I rev the car up a little bit.
