    Module Repair Lab specializes in semi-truck ECM repair, CPC4 repair, and heavy-duty diesel ECU cloning for Class 7–8 platforms. We service Cummins (ISX, X15, ISB), Detroit Diesel (DD13, DD15, DD16 + CPC4), PACCAR MX-13, and John Deere engine control modules across Freightliner, Kenworth, Peterbilt, International/Navistar, and agricultural equipment applications.

    Common failures include no-start, no communication (no-comms), CAN bus faults, derate/limp mode, voltage regulator damage, power/ground failures, and moisture-related board corrosion. Our board-level repair process restores power integrity, replaces failed communication drivers, repairs damaged traces, and bench-validates all critical circuits before return shipment.

    When supported, we provide data-preserving ECM cloning to retain VIN, calibration, and injector coding for faster installation.

    ✔ 3-5 business day turnaround
    ✔ Warranty-backed repairs
    ✔ Nationwide mail-in service

    Restore uptime with trusted heavy-duty ECM diagnostics and repair.
