Why mobile

The technician comes to you

I come to you

No waiting rooms. The service happens in your driveway, parking lot or office — where the car already is.

Professional equipment

A professional-grade diagnostic scanner (XTOOL D7BT) reads the systems a phone app can't touch.

Fast appointments

Most quick services are done in under an hour, while you work or wait in the driveway.

Affordable alternative

Clear starting prices and mobile service — a practical alternative to a trip to the dealership service lane.

What I do

Everything your car's electronics need

Diagnostics, resets, relearns and coding — electronic services only. Compatibility varies by year, make and model, and is verified before any appointment.

Questions I get asked

What exactly does 423Code do?
Electronic diagnostics, coding, resets, relearns and vehicle customization on supported vehicles. I read what your car's computers are reporting, explain it in plain English, and carry out electronic services on site — engine, transmission, brake and general mechanical repair are not part of what I do.
Will this work on my car?
Compatibility varies by year, make and model, so nothing is promised up front. Send your year, make, model, trim and engine through Check My Vehicle and I'll confirm what is supported — and tell you plainly if something isn't.
Where do you work?
Mobile service in Chattanooga and surrounding areas — your driveway, parking lot or office. Include your ZIP with your request and I'll confirm coverage before an appointment is scheduled.
What does it cost?
Diagnostics carry fixed starting prices, listed on the Services & Pricing page. Coding and customization are quoted per vehicle, because the amount of work depends on what your vehicle supports. Nothing is charged before you approve the quote.
Do I need to bring the car anywhere?
No — I come to you with a professional-grade diagnostic scanner. Most quick services (resets, relearns, coding) are finished on the spot, and a full multi-module scan takes longer.

Still unsure whether your vehicle is supported? Call or text (423) 555-0100 — or send your details through Check My Vehicle and I'll tell you what's possible.
