Modern vehicles rely heavily on electronic systems to deliver efficiency, safety, and performance. When something goes wrong, pinpointing the issue requires specialised tools and expertise.

We combine technical precision with years of hands-on experience to deliver fast, accurate results, saving you time, money, and unnecessary repairs.
Whether you drive a European performance vehicle, a family car, or a commercial van, Tyre Doctors offers advanced vehicle diagnostics in Melbourne you can trust.


What Is Car Diagnostic Testing?
Car diagnostic testing involves scanning your vehicle’s onboard computer system to identify faults, performance issues, or component failures. Most modern vehicles are equipped with numerous sensors and control modules that monitor everything from fuel injection to transmission performance.
When something goes wrong, these systems store error codes, known as Diagnostic Trouble Codes (DTCs), that point to specific faults. At Tyre Doctors, we use advanced scanners and software to read and interpret these codes, allowing us to accurately locate the source of the issue before recommending repairs.
Our diagnostic process covers:
- Engine management and emission systems
● ABS, traction, and stability control systems
● Airbag and SRS modules
● Transmission and drivetrain control units
● Cooling and charging systems
● TPMS (Tyre Pressure Monitoring System) sensors
● Auto electrical fault finding and wiring issues
What Is Auto Electrical Fault Finding?
Auto electrical fault finding is the process of locating and diagnosing electrical problems that affect your vehicle’s operation. These can include short circuits, wiring damage, sensor failures, or battery and alternator issues.
At Tyre Doctors, our auto electrical fault finding in Melbourne combines precision instruments with technician experience to trace complex faults accurately. We handle all aspects of car electrical fault finding, including:
- Battery drain testing
● Alternator and charging system evaluation
● Starter motor testing
● Sensor and wiring inspections
● CAN-bus system diagnostics
● Fuse and relay checks
● Fault finding in car electrics for lighting, instruments, and accessories
Electrical systems in modern vehicles are highly integrated. Our team ensures every test is performed carefully, protecting your car’s delicate electronic components.


Common Signs Your Vehicle Needs Diagnostic Testing
A diagnostic test should be booked any time your car displays warning lights, unusual behaviour, or unexplained performance issues. Common symptoms that indicate you may need car diagnostic testing in Melbourne include:
- Check Engine or Service lights illuminated
● Difficulty starting the vehicle
● Rough idling or stalling
● Poor fuel economy
● Intermittent power loss or limp mode activation
● Dashboard warning lights for ABS, airbag, or traction control
● Electrical accessories not working properly
● Unexplained battery drain or charging problems
Ignoring these warning signs can lead to costly repairs or safety concerns. Early detection through professional diagnostics helps resolve issues before they escalate.
