Vehicle Diagnostic and Troubleshooting Process

Start of the Workflow/Process.

Fetch existing vehicle data (VIN, Make, Model, Year) from the Vehicle Data Model using the provided identifier.

Assign a task to the Technician to inspect the vehicle for visible external damage or fluid leaks.

Create a new entry in the Diagnostic Logs model to track this specific troubleshooting event.

Assign a task to plug in the diagnostic tool and read all active and stored DTC (Diagnostic Trouble Codes).

Retrieve the descriptions and severity levels for the specific DTCs found during the scan from the Error Code Library.

Calculate a weighted severity score based on the number of active error codes and their associated risk levels.

Assign a task to perform specific physical tests (e.s., compression test, battery load test) based on identified error codes.

Update the Diagnostic Session entry with the results, measurements, and observed anomalies from the stress tests.

Aggregate all error codes found in the current session to count the total number of system faults detected.

Create a new entry in the Service Quote model including required parts and estimated labor hours.

Send an email to the vehicle owner detailing the detected issues and the proposed repair plan.

Assign a task to perform a post-diagnostic check to ensure all sensors are responding within factory parameters.

Update the original Diagnostic Session entry to 'Closed' status and attach the final conclusion.

Create a formatted PDF report containing the vehicle history, scan results, and technician notes for the customer.

Send an SMS to the Service Advisor notifying them that a high-severity diagnostic issue requires immediate parts ordering.

End of the Workflow/Process.
