Product information
The Thinktool HML Box is a connection/module solution used with a compatible Thinktool main device in commercial vehicle and heavy-duty vehicle services.
Physical Connection Coverage
Connecting the cable, adapter, or communication module to the vehicle does not prove that the vehicle is supported by the software. The physical connector, pin layout, main device, and vehicle software must be compatible simultaneously.
Product details
When selecting the HML Box, main device compatibility and the vehicle group to be used are decisive. The purchase decision should be made in the same order as the main device, cable set, and service needs.
Product details
The HML Box model is a communication module that establishes vehicle communication between a compatible Thinktool main device and 12/24 V heavy-duty vehicle electronics. Its main uses and hardware features include heavy-duty vehicle connection, commercial vehicle support, and service module functions.
The HML Box model is not a standalone tablet or connector set; it works with a compatible main device, the correct heavy-duty vehicle cables, and the relevant software package.
Product details
This communication module establishes communication between a compatible Thinktool main device and the 12/24 V heavy-duty vehicle line. Main device compatibility is checked via the main device and vehicle group before connecting the module.
The module does not create vehicle coverage on its own for commercial vehicle use; the heavy-duty software on the main device and the appropriate connector set are required together. Cable coverage must match the truck, bus, or other commercial vehicle group to be worked on. The HML Box is a vehicle communication module, not a standalone diagnostic device with a screen.
The vehicle group, software package, and physical cable set must match each other in the same service connection. When communication is established with the module, the main device, module serial number, vehicle group, and the connector used are recorded in the service record. At the end of the job, the 12/24 V connection, cables, and connectors are physically inspected again.
Product details
Before connecting the HML Box model to a heavy-duty vehicle, the vehicle type, 12/24 V power supply, and chassis socket are determined. The HML Box model connectors and cable set are physically checked. The vehicle group, supply voltage, connector, and heavy-duty software are matched.
When the HML Box model is turned on, the vehicle identity and the first communicating control unit are recorded. If the HML Box model cannot establish communication, power, socket, cable, and software selection are tested individually.
Product details
When scanning engine and emission control units with the HML Box model, the vehicle group is opened under the correct software. The HML Box model preserves engine, exhaust aftertreatment, and related powertrain codes in the initial report. Vehicle identity, connection set, and software version are added to the initial service report.
The HML Box model saves operating hours and event data accompanying the codes. Deletion or service commands are applied after the fault inspection on the HML Box model is completed.
Product details
Live data recording with the HML Box model begins by entering the engine's operating status and load information. The HML Box model collects fuel, pressure, temperature, and emission-related values under the relevant system. Vehicle identity, control unit, and software version are included in the data recording.
The HML Box model saves values with their units and measurement time. After the repair, the HML Box model takes a second recording under the same operating conditions and compares the differences.
Product details
After the service operation, the HML Box model reconnects to the same vehicle and control units. The HML Box model displays the codes from the initial report, the completed operation, and the final scan side-by-side. A second scan is taken using the same connector set and software version.
The HML Box model performs the necessary function check according to the vehicle manufacturer's procedure. The HML Box model clearly indicates ongoing codes and new findings in the customer report.
Product details
Definitive compatibility cannot be stated for the HML Box model without selecting the truck, tractor, or bus group, engine, 12/24 V connection, and connector together. The Thinkcar official coverage tool shows which system, service function, or protocol is activated for the selected vehicle and control unit for the HML Box.
The presence of a brand line does not prove that active testing, coding, programming, TPMS relearn, or security gateway access is also enabled on the HML Box.
Before ordering, prepare the VIN or full model information, model year, engine/chassis distinction, and the intended operation for the HML Box; also check the software version, license period, VCI, adapter, and regional package.
Product details
Main device compatibility, cable coverage, and vehicle group module's 12/24 V heavy-duty vehicle connection are determined. The HML Box is not a standalone diagnostic device; a compatible Thinktool tablet, heavy-duty vehicle software, and a connector set suitable for the vehicle socket are required.
J1939 or brand-specific communication support depends on the main device and software package used. Access to engine, transmission, brake, superstructure, and emission systems varies according to the manufacturer's current vehicle list. The module label, serial number, and delivered cables are checked before use.
Product details
The Launch OBDII non-OBD external HD connector set is not a direct alternative to the HML Box model. The HML Box is a heavy-duty vehicle communication module; the Launch OBDII non-OBD external HD connector set is a connector package that complements physical socket access.
Main device compatibility, cable coverage, and vehicle group must match the tablet, software package, and physical connector set to be used. The communication module does not replace the connector set, nor does the connector set replace the communication module.
Product details
Working with the HML Box model begins with writing the vehicle or equipment ID and the heavy-duty vehicle connection request into the work order. The technician prepares the main device compatibility condition and records the initial scan or connection test with the HML Box model.
Only the relevant system is opened on the HML Box model; if there is an active command or write operation, the vehicle voltage is monitored throughout the process. After the application is completed, the HML Box model rescans the same system. The vehicle group is shown in the service report along with the initial record and the operation performed with the HML Box model.
Product details
The HML Box model package includes only the power and connection parts listed by the manufacturer along with the HML Box communication module. Main device compatibility, cable coverage, and vehicle group are checked via the delivered product label and parts list.
Thinktool tablet, heavy-duty vehicle software license, and vehicle-specific connector set are not included in the package unless explicitly stated in the box contents. The module's main device compatibility and physical connector coverage are separate technical details. The warranty is valid for the purchased physical product and listed parts under the described conditions.
Product details
Upon receiving the HML Box model, the model label, serial number, box contents, and main device compatibility are compared with the order record. For the HML Box model using software, the account, language, region, and current version are recorded on the first installation day. The first test is performed with a heavy-duty vehicle connection task instead of a risky write command.
If the HML Box model is to be used with a shared workshop account, the account manager and users accessing customer data are determined. Cable, battery, probe, and accessory checks are added to the HML Box model maintenance plan.
Product details
The service record using the HML Box model includes the vehicle ID, customer complaint, main device compatibility, and heavy-duty vehicle connection request. Fault codes, relevant live data, and vehicle conditions are stored before the operation in the HML Box initial report.
The command, setting, or service function applied for heavy-duty vehicle connection is recorded with the operation name and result. After the operation with the HML Box model, the scan is repeated, maintaining the vehicle condition from the initial record. The HML Box customer report distinguishes between found faults, completed work, and ongoing findings.
