DIAGNOSE.
REPAIR.
VERIFY.

Modern vehicles are rolling computers. From CAN-bus networks and body control modules to sensor faults and intermittent gremlins, diagnosing today's cars requires more than pulling codes — it requires understanding the full electrical architecture of each platform. That's what we do at INF Performance.

DIAGNOSTIC & ELECTRICAL SERVICES

• OEM-LEVEL FAULT CODE DIAGNOSTICS

  We use manufacturer-level scan tools — not generic code readers — to pull full fault trees, freeze frame data, and live sensor readings across all control modules on your vehicle.
• ELECTRICAL FAULT TRACING & REPAIR

  Short circuits, open circuits, corroded grounds, and parasitic draws — we trace electrical faults to the source rather than guessing at parts. Proper wiring diagrams and oscilloscope testing when needed.
• MODULE & ECU PROGRAMMING

  Replacement modules and ECUs need to be coded to the vehicle. We perform OEM-spec programming and adaptation for body control modules, engine control units, transmission modules, and more.
• BATTERY, CHARGING & STARTING SYSTEM

  Battery registration (critical on BMW, Audi, Mercedes), alternator testing, starter diagnosis. European vehicles require proper battery coding or charging system faults will follow.
• SENSOR DIAGNOSIS & REPLACEMENT

  MAF sensors, O2 sensors, crankshaft/camshaft position sensors, throttle bodies, and more. We verify sensor behavior with live data before condemning components — no unnecessary part replacement.
• AIRBAG & SAFETY SYSTEM DIAGNOSIS

  SRS/airbag light on? We diagnose supplemental restraint system faults, crash data, and seat belt pretensioner issues. Safety system repair done right the first time.
• ABS & STABILITY CONTROL SYSTEMS

  Wheel speed sensor faults, ABS module issues, traction control and ESC diagnosis. We bleed and reset ABS systems properly — including vehicles that require scan-tool-activated bleed procedures.
