From vehicle to decision

Plug in. Scan. Decide.

01
Plug in
Plug the ULTRA adapter into the OBD port. Open the CarDr app.
Illustrative app screen: ready to scan.
02
Scan
Cold Scan (ignition on, engine off) captures resting battery voltage and the ECU baseline. Warm Scan (engine running) confirms what persists. 138+ OEM protocols, 100+ ECUs, 15 seconds to about a minute.
Illustrative app screen: scan in progress.
03
Decide
One merged report: severity-ranked findings, repair cost, and an Arbitration Risk Flag.
Illustrative app screen: merged scan results.

Look beyond the engine

What generic readers miss

A generic code reader sees the engine and a few codes. CarDr reads the whole vehicle.

Recently cleared codes

Code-reset signals give you context a cleared dashboard cannot.

Warning lights on at check-in

2,919 vehicles (~29%) had a warning light on in the 10,000-scan auction sample.

Module-level faults across 100+ ECUs

Read findings across the vehicle, not just engine trouble codes.

Resting battery voltage

See the voltage baseline alongside the diagnostic findings in every scan report.
