Vehicle Communication Module (VCM) and Integrated Diagnostic System (IDS) software with appropriate hardware, or equivalent scan tool

Diagnosis by Symptom gives the technician diagnostic information and direction. It suggests possible components, using a symptom as a starting point. All routines begin with any potential electrical components that can cause or contribute to the symptom described. The routines then list all possible hydraulic or mechanical components that can cause or contribute to the symptom described.
