What is safe, and what is not.
Diagnostic software can read a great deal and change a few things. Hanterill is built so you always know which is which.
Read-only by construction
Battery checks, fault scans and live readings ask the car for information. They do not change its configuration. Actions that can change the car are kept in separate flows and require confirmation.
Operations that change the vehicle
Clearing fault codes, running a service routine or resetting a control unit can change the car. Hanterill asks you to confirm each action and reports whether the car accepted it.
High voltage
Electric vehicles carry hazardous high-voltage systems. Reading battery data over a diagnostic link does not de-energise anything and does not make physical high-voltage service safe. HV service requires procedures, equipment and training from the manufacturer.
Not a substitute for manufacturer tooling
Hanterill is an independent project. It does not replace the diagnostic system supplied by the manufacturer, and it is not affiliated with Volvo Cars, Polestar or Geely. Use it to understand your vehicle, not as the sole basis for a safety-critical repair decision.
Unverified platforms
On Testing or Research platforms, the decoding still needs testing on more cars. Do not rely on battery figures or fault interpretation, and do not make purchase or repair decisions from them.
Read by default. Writes ask first.
Ordinary checks read information from the car. Clearing codes, resetting a control unit and running a service routine each require a separate confirmation.
Read-only
- Battery data
- ECU identification
- Fault codes
- Live telemetry
- Session archive and export
Changes the vehicle
- Clear diagnostic information
- Service routines
- ECU reset (force-reset loop)
Confirmation required
High voltage. Electric vehicles carry hazardous high-voltage systems. Reading data over a cable does not make it safe to work on them, and Hanterill is not a substitute for the manufacturer's service procedures.
