STEP | DESCRIPTION | |
STEP 1 | Get detailed information about the conditions and the
environment when the incident occurred.
The following are key pieces of information required to make a good analysis: |
|
WHAT | Vehicle Model, Engine, Transmission/Transaxle and the System (i.e. Radio). | |
WHEN | Date, Time of Day, Weather Conditions, Frequency. | |
WHERE | Road Conditions, Altitude and Traffic Situation. | |
HOW | System Symptoms, Operating Conditions (Other Components
Interaction).
Service History and if any After Market Accessories have been installed. |
|
STEP 2 | Operate the system, road test if necessary.
Verify the parameter of the incident. If the problem cannot be duplicated, refer to “Incident Simulation Tests”. |
|
STEP 3 | Get the proper diagnosis materials together including:
Identify where to begin diagnosis based upon your knowledge of the system operation and the customer comments. |
|
STEP 4 | Inspect the system for mechanical binding, loose
connectors or wiring damage.
Determine which circuits and components are involved and diagnose using the Power Supply Routing and Harness Layouts. |
|
STEP 5 | Repair or replace the incident circuit or component. | |
STEP 6 | Operate the system in all modes. Verify the system works properly under all conditions. Make sure you have not inadvertently created a new incident during your diagnosis or repair steps. |
