Documentation
Guides for the cable, car and readings.
Start with the connection, then follow a reading back to the control unit that supplied it. The reference pages cover the protocol details.
Start from a task
- Connect a carCable, interface and network setup, then your first session.
- Check what is supportedPlatforms, status labels and what each one means for your model.
- Read fault codesScan every module, read statuses and freeze frames, and clear with confirmation.
- Understand a battery resultWhat state of health, state of charge and the cell-group numbers actually mean.

Start
- Getting startedInstall Hanterill and open your first session.
- Install on your computerChoose the right download, verify it and handle first-launch prompts.
- ConnectionENET cable, Ethernet interface and network setup.
- Hardware and adaptersCables, interfaces and link types, and what you supply.
- Supported vehiclesPlatforms, status labels and what each one means.
- Screen tourWhat every screen in the app is for, and which ones matter day to day.
- Interface and languagesInterface languages, themes, keyboard use and per-OS setup.
- TroubleshootingCommon failures, what each one means, and what to try.
- Get helpCollect a support bundle and report a problem without sharing vehicle identifiers.
- Common tasksFollow a short path through the app for an inspection, fault, repair or software check.
Diagnostics
- Battery diagnosticsSOH, SOC, cell-group potentials, topologies and thermal data.
- ChargingRead charge-port status and investigate a reported charging limit.
- Parasitic drainRead the parked-current estimate and distribution of stored samples.
- DTC scanningReading fault codes by status, freeze frames, clearing and diffs.
- Live telemetrySampling channels on a cadence, recording a run, and replaying it later.
- Subsystem telemetryThe per-system screens: climate, drive units, power, steering, TCAM, GPS and service schedule.
- Module dataEvery named readout group per module: values, lifetime histories and timelines.
- Driving and displayWhat the instrument cluster logged: trips, the odometer verdict, service intervals and display data.
- Inspection reportsThe scored pre-purchase inspection and how its rules work.
- Reading resultsCheck coverage, freshness and evidence before relying on a number or verdict.
- Sessions and evidenceSave captured readings, compare visits and export records.
- Captures and sweepsWhat a full capture collects, how it progresses, and how to stop it.
- Firmware and inventoryReading module software versions, and proving what a workshop visit changed.
- Service functionsThe write operations: routines, resets, the clear flow and their confirmation contract.
- Engine diagnosticsThe combustion and hybrid path on CMA and SPA cars.
- Vehicle configurationRead the current option map and check available retrofit evidence.
Reference
