Streamline commercial trailer maintenance with the Autel Trailer PLC Connector. Designed to interface with the industry-standard SAE J560 7-way connector, this heavy-duty adapter enables commercial vehicle technicians to perform direct Power Line Communication (PLC) diagnostics on trailer Anti-Lock Braking Systems (ABS) and Electronic Control Units (ECUs)—with or without a tractor truck present.
When paired with your Autel MaxiSYS Commercial Vehicle diagnostic tablet, the TRAILERPLC adapter allows you to read fault codes, inspect ABS warning lamp status, and run functional system tests efficiently across your fleet or repair shop.
Key Features & Benefits
