OEM Factory-Level Software

Vehicle Programming &
Diagnostics

Most independent shops can't do what we do. Hyarcs Auto Repair uses OEM factory-level diagnostic and programming software — the same tools your dealership uses — to perform ECU reflashing, key coding, module programming, ADAS recalibration, and advanced diagnostics on all makes and models.

Programming Services

Dealer-Level Technology at Independent Prices

ECU Reflashing & Calibration

Engine control unit (ECU) reflashing updates your vehicle's software to the latest manufacturer calibration, fixing bugs, improving performance, and resolving drivability issues.

Key Coding & Immobilizer Programming

Lost your key? Added a spare? We program new keys and fobs to your vehicle's immobilizer system using factory software — no dealership visit required.

Module Programming & Replacement

We program replacement control modules — TCM, BCM, ABS, TPMS, and others — to your vehicle's VIN so they communicate correctly with the rest of the car's systems.

ADAS Recalibration

After a windshield replacement or collision repair, your advanced driver assistance systems (ADAS) — cameras, radar, lane departure, and automatic braking — must be recalibrated. We handle it.

OEM Diagnostics

Factory diagnostic tools read deeper fault codes than generic OBD scanners — giving us complete visibility into every system in your vehicle for accurate diagnosis and faster repairs.

Pre-Purchase Inspection

Before you buy a used vehicle, we run a complete OEM diagnostic scan to reveal hidden codes, pending faults, and module irregularities that a visual inspection can't catch.

Why OEM Matters

Not All Diagnostics Are Created Equal

Generic OBD-II scanners read basic fault codes — but they miss the deeper, manufacturer-specific data that lives in your vehicle's proprietary systems. Our OEM factory software communicates with every module in your car at the same level as the dealership's tools.

This means we can program keys, update software, recalibrate sensors, and diagnose issues that other shops simply can't access — saving you a dealership trip and dealer-level markup.

FAQ

Programming & Diagnostics Questions

Can you program a key for my car without going to the dealership?

Yes — we program new keys, fobs, and push-button start systems to your vehicle using factory software. We support most domestic, Asian, and European makes.

What is ECU reflashing?

ECU reflashing updates your engine control unit's software to the latest manufacturer calibration. It can fix drivability issues, improve fuel economy, resolve fault codes, and address technical service bulletins (TSBs).

Why does my ADAS need recalibration after a windshield replacement?

Your front camera is mounted to the windshield. When the glass is replaced, the camera's mounting angle changes slightly — which throws off the calibration of lane departure, automatic emergency braking, and adaptive cruise systems. It must be recalibrated to safe parameters.

Can you program a replacement BCM or TCM?

Yes — we program replacement body control modules (BCM), transmission control modules (TCM), and other controllers to your vehicle's VIN using manufacturer software.

My check engine light is on. Can you diagnose it?

Absolutely. We use OEM factory diagnostic tools to read all available codes — not just basic OBD-II data — and give you a thorough diagnosis with repair options and pricing.
