The used-EV blind spot

The two things you can't see
are the two that cost the most.

A used Tesla's price hangs on battery health and real mileage — and both are invisible on a test drive. Dashboards can be rolled back. A tired pack looks perfect until winter. TSLASCAN reads the numbers the car keeps to itself.

Odometer rollback

Mileage is edited on the used market every day. A single dashboard number is trivial to fake — and impossible to challenge without the car's own records.

Hidden degradation

Two identical cars can be 8% or 20% worn. That gap is thousands in range and resale — and it never shows on a short drive.

Swapped or salvage packs

A replaced or flood-salvaged pack carries a different history than the chassis. Without pack identity and calendar age, you'd never know.

What it reads

Dealer-grade diagnostics,
in the palm of your hand.

Everything below comes from the battery's own broadcast data — measured, not estimated.

True State of Health

SOH from the pack's own factory Beginning-of-Life energy, read per car — not a generic lookup table. The real capacity left, in kWh.

Odometer tamper detection

Cross-checks up to three independent mileage sources (gateway, BMS, dashboard). A rollback has to fake every one of them to pass.

Per-cell 3D map

All 96+ bricks rendered in 3D. A weak or imbalanced cell stands out instantly — height is voltage, colour is sag under load.

Under-load diagnostics

Internal resistance (DCIR) and per-cell voltage sag measured while driving — the health signals a seller can't hide at rest.

Isolation & faults

HV insulation resistance and stored BMS fault codes — early warning of moisture, wear, or a pack that's been through something.

Tamper-evident report

Every report lives on tslascan.com with a unique ID and a live device check. Screenshots can be edited; the live page can't.

Drive units & thermal

Motor torque and power on every driven axle — AWD or RWD confirmed — plus battery and powertrain coolant temperatures. The drivetrain's health, read live.

Degradation history & trend

Every scan is kept per car: SOH over time, cell balance at each charge level, and whether a weak cell is getting worse — a picture a live-only scanner can't give.

Live per-cell graphs & logging

All 96 cells charted in real time, with an optional one-tap raw log recorder that captures every scan for deep offline analysis.

Three steps

Plug in. Drive. Show the buyer.

Plug it in

Connect the analyzer to the car's diagnostic port. It's listen-only — it reads the bus and never writes a single command to the car.

Park, then drive

A minute parked captures cell balance; a short drive captures resistance and sag under load. Data streams to your report, encrypted end-to-end.

Scan & share

Scan the QR on the device — or open the link — for a clear BUY / CAUTION verdict you can hand straight to the buyer.

Full lineup

Every Tesla. Including Cybertruck.

One analyzer, the whole range — from the first Model S to the latest Cybertruck.

The report

A verdict anyone can read
— and verify.

No jargon dump. A used-car buyer sees a green BUY or an amber CAUTION, the SOH, the mileage cross-check, and the 3D cell map. A live link on our domain proves it wasn't Photoshopped.

Questions, answered

Is it safe for the car? Can it break anything?
Yes, it's safe. The analyzer is listen-only: it reads the diagnostic bus and never sends a command to the car. It can't change settings, unlock anything, or affect driving.
How does it catch a rolled-back odometer?
A Tesla stores mileage in more than one place — the gateway, the battery module, and the dashboard. TSLASCAN reads up to three of them and cross-checks. A rollback that only edits the dash gets caught by the others.
Does it really work on Cybertruck?
Yes. The analyzer supports the full lineup — Model 3, Y, S, X and Cybertruck — decoding each pack's battery and mileage data.
Do I need a subscription?
No. It's a one-time price of €250. Unlimited scans, unlimited cars, lifetime report hosting, and free firmware updates — no monthly fees.
How does a buyer trust the report?
Every report lives at tslascan.com with a unique device code and a live online/data check. A buyer enters the code on our site and sees the same live page — screenshots can be edited, the live report can't.
How long does a scan take?
The essentials appear within a minute of plugging in. A short drive adds the under-load numbers (internal resistance and cell sag) for the complete picture.

Make it the report every buyer asks for.

Sell faster with proof, or buy with confidence. One analyzer does both.
