Practical Workshop Diagnostic Checks
A repeatable diagnostic process helps avoid unnecessary parts replacement. Begin with the customer’s symptom and the conditions under which it occurs.
Useful Checks
- Confirm the symptom and service history.
- Check battery condition, relevant fuses, visible connectors and obvious mechanical concerns.
- Save diagnostic codes, freeze-frame information and useful live data before clearing anything.
- Consult the correct wiring diagram and test procedure.
- Test the suspected circuit or component rather than replacing it solely because its name appears in a code.
- After repair, verify the symptom and complete any required service procedure.
Tool Choice
Generic OBD2 diagnosis, manufacturer module access, active tests and programming require different levels of coverage. Confirm the exact vehicle and operation before buying equipment. Follow vehicle-specific instructions for high-voltage, restraint and other specialist systems.
