17 Automotive Test Agents - CAN, UDS, LIN, DoIP & SOME/IP
Every in-vehicle protocol in one drag-and-drop platform. From legacy CAN bus to AUTOSAR Adaptive Ethernet - no separate tools required.
OVERVIEW
Modern automotive ECUs communicate across CAN, LIN, and Ethernet simultaneously. Validating a domain controller today means running UDS diagnostics over CAN, testing SOME/IP service discovery over Ethernet, and reading instrument cluster displays with AI Vision - all in a single overnight regression cycle.
TestBot gives you 17 automotive agents covering every layer of the in-vehicle network: CAN bus signals, UDS and OBD2 diagnostics, J1939 commercial vehicle protocols, LIN body electronics, and the full Automotive Ethernet stack including DoIP, UDS over DoIP, and SOME/IP for AUTOSAR Adaptive platforms. All agents run inside the same drag-and-drop test sequence - no protocol switching, no separate tools.
Automotive Testing Capabilities
Every agent is production-grade and maps directly to a real ECU validation requirement.
CAN Bus Signal Validation
Send and receive CAN 2.0A/B and CAN FD frames using DBC file definitions. Validate signal values, message timing, bus load, and error injection across multi-channel CAN networks.
UDS Diagnostic Sessions (ISO 14229)
Automate all 22 UDS services: session management, DID read/write, fault memory (0x19/0x14), ECU reset, security access, routine control, flash programming, and software download validation.
OBD2 & J1939 Diagnostics
Query OBD-II PIDs and validate emissions-related services. Transmit and receive SAE J1939 PGNs for trucks, buses, and agricultural equipment ECU validation.
LIN Body Electronics
Schedule LIN frames as master, read slave responses, or simulate LIN slave nodes. Validate door modules, seat controllers, and ambient lighting ECUs over ISO 17987.
DoIP & Automotive Ethernet
Send DoIP routing activation and diagnostic requests over Ethernet - the standard for EV, ADAS, and domain controller platforms. Run full UDS sessions over DoIP with zero hardware beyond your PC NIC.
SOME/IP for AUTOSAR Adaptive
Call SOME/IP services, subscribe to event groups, and validate AUTOSAR Adaptive middleware on domain controllers and central compute units - no licence for a separate SOME/IP tool required.
Typical Automotive Test Scenarios with TestBot
Real-world validation tasks mapped to the agents that automate them.
| Test Scenario | Agents Used | Validated Outcome |
|---|---|---|
| ECU Cold Start Regression | CAN / CAN FD Agent + UDS Client Agent | All startup DTCs clear, boot sequence completes within spec, CAN bus load within limits |
| UDS Flash Programming | UDS Client Agent (SID 0x34–0x37) | All data blocks transferred, CRC verified, ECU boots correctly post-flash |
| Fault Injection & DTC Validation | UDS Client Agent + I/O Module Agent | Correct DTC stored, freeze frame captured, MIL status matches spec |
| J1939 Fleet Telematics | J1939 Client Agent + CAN / CAN FD Agent | All PGNs transmitted and received within timing spec, address claims resolved correctly |
| LIN Cluster Animation | LIN Client Agent + AI Vision Agent | Slave nodes respond within schedule, cluster widgets render within 200ms |
| DoIP Routing Activation | DoIP Client Agent | Vehicle announcement received, routing activation accepted, logical address confirmed |
| SOME/IP Service Discovery | SOME/IP Client Agent + SOME/IP Server Agent | Service offered and found via SD, method calls return correct payloads |
| Nightly ECU Regression (CI/CD) | CAN + UDS + Utility Agent + Jenkins | 4,000 test cases executed overnight, HTML/PDF report published, build blocked on failure |
Frequently Asked Questions - Automotive Agents
No. TestBot's CAN / CAN FD Agent uses a single CAN Adapter that is already CAN FD capable. CAN FD is enabled by firmware configuration - no additional hardware purchase is required.
