Computer Diagnostic Services
Modern vehicles rely on complex computer systems—when something goes wrong, accurate diagnostics are the first step to getting it right.
Comprehensive Vehicle Scan
We connect to your vehicle's onboard computer systems using professional-grade diagnostic equipment. We read trouble codes from all modules: engine, transmission, ABS, airbag, and body control, to get the complete picture of what's happening.
Electrical System Diagnostics
From parasitic battery drains to malfunctioning sensors, we trace electrical faults using wiring diagrams and advanced testing equipment. We find the source of the problem, not just the affected component.
Check Engine Light Diagnosis
That warning light could indicate dozens of potential issues. We retrieve and interpret diagnostic trouble codes, then perform targeted testing to identify the root cause, not just the symptom.
Drivability Diagnostics
Hesitation, surging, stalling, or rough idle? We analyze sensor data, fuel trim values, and live engine parameters to diagnose performance issues that don't always trigger a warning light.
Emissions System Diagnostics
Failed a smog test or seeing emissions-related codes? We diagnose catalytic converter, oxygen sensor, EVAP system, and other emissions components to pinpoint exactly what needs repair.
Pre-Purchase Vehicle Inspection
Considering a used vehicle? We perform a comprehensive computer scan to check for hidden trouble codes, pending issues, and signs of previous repairs that could indicate problems down the road.
