Automotive Networks
CAN and LIN Bus Testing
From CAN FD capture at 8 Mbit/s and J1939/UDS decode through ECU stimulus, physical layer validation, and fleet telematics, GSAS delivers automotive network testing across India.
What We Test
CAN and LIN Testing Services in India
Five disciplines covering CAN capture, active stimulus, LIN analysis, physical layer validation, and fleet telematics, backed by our Total Phase and AutoPi partnerships.
CAN and CAN FD Capture and Analysis
Capturing and decoding CAN and CAN FD traffic is the starting point of any automotive bus debug. GSAS deploys the Total Phase Komodo CAN Duo interface for dual-channel CAN 2.0A/B and CAN FD capture up to 8 Mbit/s, and the AutoPi CAN-FD Pro for OBD-II vehicle network access. We decode J1939, ISO-TP, UDS, OBD-II Mode $01-$09, and custom application protocols, and we automate regression test capture in CI pipelines.
- Dual-channel CAN 2.0 and CAN FD capture up to 8 Mbit/s
- J1939, ISO-TP, UDS, OBD-II decode and replay
- Vehicle diagnostics capture via AutoPi CAN-FD Pro
- Python scripting for automated CAN regression testing
- DBC file generation and signal interpretation
CAN Activity Simulation and Stimulus
Active testing requires injecting controlled CAN traffic into a device under test, not just observing existing traffic. The Total Phase CAN Activity Board Pro provides a deterministic CAN 2.0 and CAN FD stimulus source for bench testing ECUs without the rest of the vehicle network. GSAS engineers build test fixtures and scripts that drive these boards through conformance sequences, fault injection tests, and functional regression.
- CAN Activity Board Pro integration for bench test benches
- ECU conformance testing with deterministic stimulus
- Fault injection: bus-off, stuck bit, bit-flipping scenarios
- Multi-node simulation for gateway ECU testing
- Test sequence automation via Python and CI pipelines
LIN Bus Analysis
LIN networks remain the cost-effective choice for low-speed body electronics: seat motors, window controllers, mirror adjusters, HVAC blenders. GSAS provides LIN bus analysis and testing using Total Phase protocol analysers and integrated CAN/LIN bridges, and validates LIN 2.x and SAE J2602 compliance for Indian automotive suppliers.
- LIN 2.x and SAE J2602 protocol capture and decode
- Master and slave timing validation
- NAD conflict and configuration table verification
- CAN-LIN gateway ECU test strategies
- LIN Description File (LDF) driven test generation
CAN Physical Layer Validation
Protocol-layer tests cannot catch physical layer faults: dominant/recessive voltage margins, bit timing, termination impedance, EMC-induced glitches. GSAS deploys PicoScope 3000/4000 series oscilloscopes with serial decode to validate CAN and CAN FD physical layers against ISO 11898-2, measure bit timing at 5 Mbit/s, and correlate physical-layer faults with protocol-level errors.
- ISO 11898-2 CAN physical layer validation
- CAN FD bit timing measurement at 5-8 Mbit/s
- Differential voltage margin and dominant/recessive levels
- Termination impedance and bus topology diagnosis
- Serial decode overlaying physical capture for root cause
Fleet and Telematics CAN Integration
For fleet telematics, EV battery management, and vehicle data logging applications, CAN bus access is the foundation. GSAS uses the AutoPi TMU CM4 telematics platform to build custom fleet telematics solutions that stream CAN data to the cloud, log trip events, and integrate with existing fleet management systems. Ideal for Indian logistics operators, EV fleets, and commercial vehicle telematics programmes.
- AutoPi TMU CM4 telematics platform deployment
- Custom CAN data pipelines to cloud and fleet platforms
- EV battery data capture and state-of-health monitoring
- Trip event logging and anomaly detection
- Integration with existing fleet management systems
