Call (818) 500-1939Modern vehicles rely on dozens of interconnected computer systems to manage everything from engine performance to emissions controls. When your check engine light comes on, your car is trying to tell you something — and our advanced diagnostic scanners can translate that message into a clear, actionable diagnosis.
At A Plus Auto Shop, master mechanic Armik uses state-of-the-art OBD-II diagnostic equipment to read trouble codes directly from your vehicle's ECU. We don't just read the code — we interpret it in the context of your specific vehicle, run additional tests to confirm the root cause, and provide you with an honest assessment of what needs to be fixed.
Comprehensive computer diagnostics services for all makes and models at A Plus Auto Shop.
When your check engine light illuminates, it could indicate anything from a loose gas cap to a serious engine problem. We read and interpret all diagnostic trouble codes (DTCs) to identify the exact issue, saving you time and money on unnecessary repairs.
We use professional-grade OBD-II scanners that go beyond basic code readers. Our equipment accesses manufacturer-specific codes, freeze frame data, and live sensor readings to provide a complete picture of your vehicle's health.
Modern cars have hundreds of sensors monitoring everything from oxygen levels to wheel speed. We test individual sensors and control modules to pinpoint failures that generic scanners might miss.
If your car is running rough, getting poor fuel economy, or failing smog checks, our diagnostic process identifies the underlying cause — whether it's a failing catalytic converter, misfiring cylinder, or faulty emission control component.
Thinking about buying a used car? Our comprehensive diagnostic scan reveals hidden issues that a visual inspection might miss, including pending trouble codes, emission readiness status, and system health indicators.
Electrical problems can be tricky. We use specialized diagnostic tools to trace wiring faults, test charging systems, and diagnose issues with power windows, locks, lights, and other electrical components.
