- Resting battery voltage on every report Captured during the Cold Scan.
How it works
Plug in. Scan. Decide.
A code list tells you what the vehicle reported. A purchase decision needs to know what it will cost and what you should hold back from the bid.

Why scan before you buy
In an auction sample of 10,000 scans
A code reader at the lane would not have told you.
Illustrative example
A scan at appraisal finds a $1,200 repair and past resets. The dealer negotiates $1,000 off the trade.
The sample is auction scan data; the example is illustrative and not a guarantee.
Dealer questions.
Is there a contract or minimum term?
No — billing is month-to-month. The Starter kit is $599 for 2 devices + 50 scans, then $299 a month for 50 scans shared across devices, with 30-day cancellation. Payment by major credit card, debit, or ACH.
How fast is a scan?
Many scans complete in 15 seconds to about a minute (vehicles with more ECUs take about a minute), although actual scan time varies by vehicle — some vehicles have more ECUs and require more communication time than others.
What do I need before I scan?
A compatible iPhone or Android phone, Bluetooth turned on, mobile data turned on, the OBDIQ app installed, your login credentials ready, the vehicle started, and the ULTRA adapter fully seated in the OBD port.
Where exactly is the OBD port?
On almost all vehicles since 1996: under the dash on the driver's side, below the steering wheel. Some are behind a small flip-down panel. It's the 16-pin trapezoid connector.
What does it catch that a generic reader misses?
Advanced B, C and U codes across 100+ ECUs, recently cleared codes, transmission and radar codes, and per-VIN repair cost bands.
Can my whole team use it?
Yes — no extra charge for additional users; your CarDr admin adds them in the web portal.
