Quickly troubleshoot lighting and air brake systems with the Super MUTT® PRO Edition—a compact, rugged solution for 7-way electrical and air brake diagnostics. Engineered for heavy-duty fleets, this versatile unit combines 12/24V operation with real-time circuit analysis and dynamic brake actuation. Operates all functions remotely up to 200 feet away, making it ideal for use in yards, shops, or on the roadside. Easily detects shorts, ground faults, and wiring issues while minimizing guesswork and speeding up inspections. When testing ABS systems, the supermarket can be used to trigger blink codes. For more advanced ABS diagnostics, see the Alpha MUTT® series.
