Dual-use

One reader. Two worlds.

The same diagnostic protocol that clears the CEL on Sunday morning also probes the standby equipment in the workshop — both sides earn the slot on the platform.

For the garage
Read & clear check engine, monitor live data, prep before the next trip.

Read & clear check engine, monitor live data while driving, prep your car before a road trip or emissions test.

For the home
Same diagnostic protocol across standby equipment, generators, and 12V batteries.

Verify HVAC electrical draw at home, troubleshoot generator load, test 12V battery health on solar setups or backup power. Same diagnostic protocol, broader use.

In the box

What you get in the box.

Open the case, plug in the cable, and the first diagnostic is one tap on the app away from open.

Quick-start cardPair Bluetooth, read the first code, and clear it in under five minutes.

Pays for itself

$0 vs $120 typical dealer diagnostic.

One CEL pulls into the shop and the diagnostic fee alone runs $90–$150. The reader clears it in the driveway for free — and pays for itself the first time it does.

With reader
$0
Free — use the reader you own.

Plug in, pair the app, clear the code in under five minutes. Skip the appointment, skip the wait, skip the fee.

Without reader
$120
Typical dealer diagnostic fee.

One shop visit for a single CEL read runs the typical $90–$150 — before any repair work begins. The reader costs less than a single trip to the bay.
