Fault Code Retrieval
Obtaining diagnostic information from your PGM-Fi
ECU.
Introduction
As the PGM-Fi system and microprocessors in general
have evolved over the years, so have the ways in which
PGM-Fi reports diagnostic information to the outside
world.
The three main methods are:
- A row of LED's indicating individual faults.
- Timed flashing of an LED in a sequence, to
produce a code number
- Serial data-link to obtain both stored faults
and live data from the ECU.
- A standard protocol such as OBD-2, for again
both faults and live data.
