Komatsu 22M-06-23101 Dash Display Repair Service

Professional diagnostic and board-level repair service for this Komatsu 22M-06-23101 Dash Display.

The Komatsu 22M‑06‑23101 is a tachometer/monitor assembly used in the PC20MR–PC50MR‑2 series excavators to display engine speed and other operating parameters. Common failures on this board include burned or cracked ICs, blown electrolytic capacitors, and frayed signal traces that cause intermittent or frozen readouts; power supply decoupling issues often lead to voltage spikes damaging the display circuitry. Begin by verifying the 12 V DC rail to the panel is within spec and checking for any visible arcing or corrosion on the connector pins, then inspect the board for swollen capacitors or cracked solder joints, and finally review the diagnostic LEDs or error codes from the excavator’s central control unit.
