OBD-II Parameter Identification (PID) Access

WARNING: This page is about a different car, the 2005 Mazda MPV. However, it is still accessible from the selected car via links, so may be relevant.

The PID mode allows access to certain data values, analog and digital inputs and outputs, calculated values and system status information. Since PID values for output devices are PGM internal data values, inspect each device to identify which output devices are malfunctioning.
