Diagnosis and Testing Information

ELEMENTS OF DIAGNOSIS AND TESTING 

Diagnosis and Testing may include:

• Preliminary Inspection
  • In older articles, Inspection and Verification

• Symptom Chart
• DTC Chart
• Pinpoint Tests
• Component Tests

Some diagnostics may be contained in Symptom Based Diagnostics. Some engine performance and emission diagnostics may be placed in a separately published Engine Controls article.

MODULE NAMES MATCH THE DIAGNOSTIC SCAN TOOL 

Module names and PID names in this article match the Ford diagnostic scan tool: IDS.

The same diagnostic scan tool module name is found in some DTC definitions (for example, U024B Lost Communication with Seat Control Module "G").

MODULE DESCRIPTIVE NAMES 

A descriptive name is sometimes added to the diagnostic scan tool name to clarify module function. The descriptive name will be followed by the diagnostic scan tool acronym in brackets.
