The TRP Diagnostic Pro from PACCAR Parts is a bidirectional diagnostic tool for all makes and models of light-, medium-, and heavy-duty trucks. It comes with a one-year subscription to a diesel repair platform and digital library to diagnose fault codes, explore repair options, and look up parts, and can perform forced regenerations, DPF resets, cylinder cutouts, and more. Billed as a way to turn a smartphone into a heavy-duty diagnostic tool, the TRP Diagnostic Pro allows technicians to log in remotely and walk repair shops through diagnostics and find parts linked to fault codes, wiring diagrams, repair guides, and more. ABS coverage is included.
