OBD Vehicle Systems Development NAPRO

OBD solutions built to fit your specific application

A pioneer in vehicle electronic diagnostics in Brazil, NAPRO Eletrônica Industrial has more than 35 years of experience developing OBD communication solutions. With an engineering team specialised in automotive protocols — CAN, ISO 15765, SAE J1979, SAE J1939, ISO 14229 (UDS), KWP2000, ISO 9141-2, LIN, FlexRay, DoIP, among others — the company develops custom solutions for automakers, importers and systems manufacturers.

Unlike generic off-the-shelf tools, NAPRO solutions are built to match the specific electronic architecture of the customer's vehicle or component, with support for multiple CAN buses and dedicated interfaces. All projects include hardware, firmware, interface software and technical documentation, with support across the whole of Brazil.

Proprietary Scanners For OEMs and dealer networks
ECU Programming UDS flash programming
End of Line Production line testing
Commissioning Multi-ECU configuration

Solutions we develop

SolutionDescription
Proprietary scanners Exclusive diagnostic tools for a specific brand or vehicle platform, with OBD data reading and writing, access to proprietary systems and generation of traceable reports.
Dealer network scanners Standardised systems for authorised service networks, with role-based access control and connectivity to the manufacturer's infrastructure.
IUPR reading tools Systems dedicated to reading and analysing on-board diagnostic monitors (In-Use Performance Ratio), for vehicle inspection and emissions auditing.
ECU flash programming Stations for programming and reprogramming firmware in ECUs, with version control, operator authentication and full process traceability.
End of Line (EOL) testing Systems integrated into the production line for functional verification of ECUs at the end of assembly, with DTC reading, parameter validation and automatic reporting.
Commissioning stations Platforms for sequential configuration and activation of multiple ECUs in complex vehicles, with support for multiple CAN buses and software-controlled actuation.
Special interfaces and adapters Development of interface hardware for proprietary connectors and pinouts, bus adapters and protocol converters.
