Active CAN-bus wiring diagnostic — in plain English
Replaces the classic multimeter + oscilloscope + laptop-with-CAN-sniffer stack with one box. Actively transmits and listens on the bus, watches for signaling-level faults, and prints plain-English error codes a technician can act on. Built for the people who actually fix vehicle and industrial CAN wiring in the field.
Why this controller vs. the conventional setup
- Active transmit-and-listen — sends test frames and watches for bus response. Catches signaling-level faults that passive continuity testers miss.
- Real-time fault isolation — locates the fault while you're at the connector, not after the test run.
- CAN-H / CAN-L voltage readings — numeric values so you know which wire is off-nominal.
- Wiggle-test mode — operator wiggles the suspect connector; tool calls out intermittent faults as they happen. Replaces the “shake the harness and watch for the error on the scope” routine.
- Plain-English error codes — not raw CAN error frames; text a tech can act on without scope expertise.
- Termination check — flags missing, extra, or out-of-spec 120 Ω termination at the bus ends.

FAQ
Does this decode J1939 / OBD-II / proprietary diagnostic codes?
No — this is a wiring-layer tool. Use a CAN analyzer + protocol-decode software for message-layer work. This tool finds wire and connector faults that those analyzers can't reliably identify.
Does it work on heavy equipment / marine / industrial CAN?
Yes. J1939 (truck, bus, ag/forestry), NMEA 2000 (marine), and industrial CAN networks all use classic CAN wiring topology, which is what this tool diagnoses.
How is this better than a multimeter?
A multimeter measures continuity and resistance — it misses signaling-level faults like a wire that conducts DC but corrupts CAN frames, or a connector that's intermittent only when stressed. Active transmit-and-listen catches those.
How is this better than an oscilloscope?
A scope catches signaling faults but requires reading differential CAN waveforms in real time and knowing what's nominal. This tool encodes that scope-reading expertise into plain-English output.
