What's inside the Carly Enterprise app.

Carly Enterprise app β€” feature overview after connecting a vehicle Carly Enterprise app β€” further features incl. battery check

Fault Memory Analysis

Reads all installed control units at OEM level and turns fault codes into clear, prioritised findings β€” not just raw DTCs.

VIN Check & Mileage Control

Checks mileage and vehicle identity across all control units for consistency β€” exposing manipulation before purchase or valuation.

Vehicle HistoryLive

Bundles diagnostic, mileage and fault history into one complete vehicle record β€” including recorded accident events, which CrashData drills into down to the control-unit data.

Battery Check (SoH test)Supported vehicles

Assesses the state of health of the high-voltage battery in EVs and plug-in hybrids (PHEV) β€” CARA-certified.

CrashDataBeta

The perfect complement to Vehicle History: reads historical accident events from every involved control unit via OBD and records them completely.

The features build on each other: the more of them you use per vehicle, the more complete the picture β€” Vehicle History and CrashData, for instance, combine into a seamless accident record. The available scope depends on the vehicle: Battery Check (SoH test) appears for supported EVs and plug-in hybrids; CrashData is in beta and is being rolled out to more models step by step.

TÜV NORDData cleansing is a separate function reserved exclusively for TÜV NORD users β€” and therefore deliberately not listed here.
