Why OBDIQ

Faster, deeper, wider.

The same three advantages that make ULTRA different on the lot, in the palm of a technician's hand.

Faster

Results in under 15 seconds

Vehicle monitors and full diagnostic results before you've finished walking around the car.

Deeper

90%+ OEM coverage

Advanced B, C, U and P codes that generic OBD-II readers never surface.

Wider

138 OEM protocols

Dynamic pin reconfiguration reaches 100+ ECUs across virtually every make on the lane.

In the App

Six screens, one scan.

Straight from the current build — the exact flow an appraiser or technician runs on a real vehicle.

OBDIQ home screen with Start Scan, Completed Reports, and Info and Settings — 01 Start Scan, scan history, and device setup — the whole app is three taps deep.

Choice between full scan with voltage check and engine-only scan — 02 Voltage-first scan or engine-only — checking voltage first stops a weak battery throwing ghost codes.

Turn ignition on, do not start prompt before the voltage check — 03 Guided setup: key to ON, engine silent — the only condition where resting voltage is honest.

Battery resting voltage gauge reading 12.00 volts with engine off — 04 Battery resting voltage is graded on the gauge before a single module is queried.

OBD IQ ULTRA scan in process with VIN and odometer decoded — 05 VIN and odometer decode instantly while ULTRA sweeps every reachable ECU.

Completed scan summary for a 2023 Ford F-150 showing two codes, emission test pass, and code reset status — 06 Code summary by category, emissions readiness, code-reset status — then copy the report URL.

The Film

Watch the app scan a live vehicle.

Battery voltage check through full module sweep to finished report — uncut, on a real car.

Inside the App

Eight IQ modules on every scan.

Each scan produces a structured read — not a code list you have to interpret yourself.

Repair Summary IQ

A breakdown of repair needs with parts and labor cost estimates priced to the vehicle.

Vehicle IQ

Year, make, model, trim, drivetrain and engine specifics decoded straight from the VIN.

Code Summary IQ

DTCs prioritized and categorized by severity so critical faults surface first.

Emissions Readiness IQ

Monitor status across O2 sensor, catalyst, EVAP and EGR — inspection-ready before you drive.

Vehicle History IQ

Maintenance, repair and ownership history tied back to what the current scan is seeing.

Safety Recalls IQ

Open NHTSA recalls for the VIN, folded into the same report.

Pricing Valuation IQ

Real-time market value estimates informed by local geographic data.

Code Reset IQ

Detects codes cleared shortly before the scan — present on roughly 20% of units.
