Component Testing

We provide precise, standalone testing for electronic control units (ECUs), validating their behaviour before they’re integrated into a vehicle system. Using our custom-built diagnostic scripts and test tools, we verify that each module responds correctly to diagnostic requests and meets all defined communication and performance criteria.

Advanced CAN & Fault Simulation
Our test suites go beyond basic validation. We subject ECUs to a range of simulated network and power conditions to assess how they perform under stress, including:

• Fault Tolerance Testing – Simulating Bus Off conditions, network faults, and invalid message patterns to ensure robust communication handling.

• Quiescent Current Measurement – Measuring standby current to identify parasitic drain issues before they reach the vehicle.

• Voltage Variation Testing – Evaluating ECU response during over- and under-voltage conditions, such as during cranking or low battery scenarios.

• Message Timing & Repetition Checks – Ensuring correct CAN message behaviour and compliance with timing tolerances.

These services are regularly delivered in partnership with OEM engineering teams, but are equally suited to Tier 1 ECU suppliers looking to validate early-stage prototypes or refine their modules ahead of production integration. Our modular test approach supports faster issue resolution, improved quality assurance, and smoother handoff during platform development.
