The Six Step Diagnostic Process used by FCA US LLC is a time proven process. The basic concepts of this process have been used by others for problem solving for many years. The successful application of this process requires a solid understanding of the conditions that affect each step, and when its time to advance to the next step. These conditions based on experience formulate what is known as "Best Practices".
When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory accessories added to the vehicle before doing any diagnosis. If the vehicle is equipped with any add-on's, disconnect them to verify they are not the cause of the problem.
| 1) VERIFY THE CUSTOMER COMPLAINT | |
| 2) DETERMINE RELATED SYMPTOMS | Do this by performing operational checks on components that are in the same circuit (Refer to the wiring diagrams). |
| 3) ANALYZE THE SYMPTOMS | Use the appropriate SYSTEM WIRING DIAGRAMS to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. |
| 4) ISOLATE THE TROUBLE | |
| 5) REPAIR THE TROUBLE | |
| 6) VERIFY PROPER OPERATION | For this step, check for proper operation of all components on the repaired circuit (Refer to the wiring diagrams). |
