Diagnostic Plan

Understanding Diagnostics

Trial and error creates inconvenience for the Customer and the Service Department when mis-diagnosis or longer waits occur as the technician tries different repair attempts. This is against BMW's promise to the customer to "Fix it right the first time, on time, every time".

If the vehicle is not repaired efficiently the productivity of the technician suffers. Taking some time at the beginning to plan a diagnostic course of action can help give structure to what may appear in the beginning to be a chaotic situation.

As future systems increase in complexity so does their dependency on the Diagnosis Program as the principle tool for troubleshooting. However, the importance of understanding the calculated steps of a basic troubleshooting plan is just as important as before.

There will always be instances where the Test Modules provided by the DISplus need to be supplemented by a thoughtful diagnostic plan that is created by the skilled Technician. A parallel diagnostic plan that includes proper recording of test data along with the Diagnosis Program is a good habit to follow every time that troubleshooting is required.

A successful diagnostic plan will:
- Save repair time.
- Satisfy the customer by reducing vehicle down time.
- Increase Center profitability.
- Increase technician pride and earnings.
