New Diagnostic Process
IDS has been updated with the goal of providing a clear diagnostic strategy and tool navigation path to the technician. With Symptom Driven Diagnostics (SDD), the technician is able to begin the diagnostic process by identifying the specific symptoms of a customer concern using Symptom Maps incorporated into the
SDD software. A diagnostic strategy can then be structured around only the DTCs that are relevant to those symptoms. SDD can also provide links to other service information to support the diagnostic process.
Symptom Maps are incorporated into the SDD software, and allow the technician to target DTCs and diagnostic routines based on a specific set of symptoms. Symptom Maps are organized by major vehicle system as follows:
Module Communications Network
Maps are then further structured by System and Sub-System details to provide lists of possible symptoms at 2 levels.
Symptom Maps are used by SDD in conjunction with DTCs. In order to ensure the best possible recommenda- tions to achieve FRFT repairs, the technician must input ALL vehicle symptoms that match the customer concern.
