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:

  1. A row of LED's indicating individual faults.
  2. Timed flashing of an LED in a sequence, to produce a code number
  3. Serial data-link to obtain both stored faults and live data from the ECU.
  4. A standard protocol such as OBD-2, for again both faults and live data.
