Expanded Diagnostic Protocols Table

Expanded Diagnostic Protocol Table:

The table lists the string of characters entered in a generic scan tool when accessing enhanced diagnostic Parameter Identification (PID) that may not be common on all OBDII vehicles.

NOTE: A formula may need to be performed on an Expanded Diagnostic Protocol PID for displaying a value in volts.

Example: 32000 Counts divided by 13107 = 2.44 Volts (scaled from 0 to 5)
