Troubleshooting Wiring Problems
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 items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem.
Perform the following Six Step Diagnosis Process:
- Verify the problem.
- Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit (Refer to the appropriate wiring information ).
- Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue.
- Isolate the problem area.
- Repair the problem area.
- Verify the proper operation. For this step, check for proper operation of all items on the repaired circuit (Refer to the appropriate wiring information ).
The Six Step Diagnosis Process used by Chrysler 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".
