The vehicle's computer generates and assigns fault codes
whenever it detects a problem in any of the various systems
that it monitors and/or controls. Once the Code Reader is
connected to the vehicle's Test Connector(s), the user can
signal the computer to perform the Self-Tests (by pressing the
TEST/HOLD button). The computer then starts performing a
Self Test of all the components and/or circuits it controls. The
results of the tests are sent to the code reader as numerical
codes to help the repairperson pinpoint a particular problem in
any of the computer control systems.
This Code Reader is designed to retrieve Diagnostic Trouble
Codes from Ford EEC-IV and MCU systems only.
