FAQ's
What does a car diagnostic test include?
A car diagnostic test typically involves connecting the vehicle to a specialised scan tool that reads fault codes from the engine control unit (ECU). The process can identify issues with sensors, ignition, fuel system, transmission, exhaust, and other electronic components. In addition to scanning for codes, diagnostics may also include live data monitoring, battery and charging system checks, and electrical troubleshooting.
Why is my check engine light on?
A check engine light can be triggered by a wide range of issues, from something minor like a loose fuel cap to more serious problems such as sensor failures, ignition faults, or catalytic converter issues. It is a warning that the vehicle’s ECU has detected an abnormal reading or malfunction. A diagnostic test is the most effective way to identify why the light came on and determine whether the problem requires repair.
Can diagnostics detect electrical problems in vehicles?
Yes, diagnostics can detect many electrical problems in cars, 4WDs, and heavy vehicles. Modern scan tools can highlight errors in sensors, relays, wiring circuits, and control modules. Beyond ECU scanning, technicians often perform additional electrical troubleshooting to find parasitic battery drains, poor connections, and grounding issues.
