TST13C CAN Bus 13 7 Pin Towbar Socket Tester

The Draper TST13C is a professional towbar socket tester designed specifically for modern vehicles with 12V CAN Bus electrical systems. This diagnostic tool enables efficient testing of both 13-pin and 7-pin towing sockets fitted to the rear of vehicles, making it essential equipment for workshops, mobile mechanics and fleet maintenance operations. Featuring a generous 5-metre cable, this tester allows convenient single-person operation without requiring an assistant in the vehicle cab. The clear LED display provides instant visual confirmation when towbar functions are detected, streamlining the diagnostic process for both routine checks and fault-finding tasks. The supplied adaptor ensures compatibility with both 13-pin and 7-pin socket configurations commonly found on UK vehicles. Ideal for garages carrying out pre-MOT checks, towbar installation work or general trailer electrical troubleshooting, the TST13C includes a self-test facility to verify the tester itself is functioning correctly before use. Its compact dimensions and relatively lightweight construction make it practical for mobile mechanics working on-site or workshop technicians diagnosing caravan and trailer wiring issues.
