Why “Repair + Clone” Beats Parts Swapping
- Diagnostics first: power rails, grounds, CAN/J1939 layers, thermal stress points.
- Keep calibrations: cloning preserves known-good config and reduces reprogram friction.
- Bench-validated: comm stability, reference integrity, key I/O before return.
- Nationwide & predictable: schedule labor; coordinate multi-unit fleet staging.
- Service-only: no DIY bench kits—professional results only.

Truck ECM Repair & Heavy-Duty ECM Cloning — CPC4, PACCAR MX-11/MX-13, Cummins Celect / Celect Plus / CM871
We specialize in truck ECM repair and heavy-duty ECM cloning for U.S. fleets and owner-operators. Our electronics-first workflow resolves no-start, no communication on CAN/J1939, SPN/FMI fault storms, derate/limp, and random shutdowns—then preserves your calibrations when cloning is required. Platform coverage includes Detroit CPC4, PACCAR MX-11/MX-13 ECM (Kenworth/Peterbilt), and Cummins Celect / Celect Plus / CM871 ISX.
Typical fixes address power-rail instability, heat-fatigued regulators, corroded interfaces, CAN transceiver failures, and vibration-driven solder fatigue. Our process: Intake → Diagnostics → Clone + Repair → Bench Validation → Return. Standard turnaround is 2–4 business days after receipt with optional overnight return and a clear 3-month warranty.
ECM Service FAQ — Detailed Answers
What info should I include with my ECM?
Include contact details, VIN/engine model, module type (CPC4, PACCAR MX-11/MX-13, Celect/Celect+, CM871), symptoms (codes/SPN-FMI), and any history (prior repairs, water intrusion, jump starts, harness issues). This speeds accurate diagnostics and reduces back-and-forth.
Turnaround time & rush options?
Typical bench time is 2–4 business days after receipt. Overnight return is available. For fleets with multiple units, we can stage batches and coordinate ship windows to match your bay schedule.
Do you offer cloning? What if my ECM is not repairable?
Yes—Clone + Repair. If your ECM is not repairable or you want a faster path, we clone your calibration/configuration to a healthy donor (when available) and bench-validate before return. You retain your known-good programming to minimize install friction.
Do I need programming after install?
In most cases, no when cloning is performed correctly and the donor hardware matches the application. After install, clear codes, follow OEM power-up, and confirm communication. If the truck has other issues upstream (wiring/sensors), codes may return until addressed.
Which platforms are your core focus?
CPC4 (Freightliner/Detroit), PACCAR MX-11/MX-13 (Kenworth/Peterbilt), Cummins Celect / Celect Plus / CM871 (ISX). We also see Detroit DDEC and common International/Navistar, Volvo/Mack, and CAT on-highway modules.
Symptoms you handle most often?
No-start or intermittent start, CPC/MCM or ACM handshake loss, CAN/J1939 comm drops, SPN/FMI fault storms, derate/limp mode, random shutdowns, 5V reference faults, moisture/corrosion intermittents, heat/vibration-related failures.
Water damage or burnt boards—still repairable?
We’ll evaluate, but severe corrosion, burn-through, or multi-layer damage can exceed safe repair. If so, we’ll recommend cloning to a donor or provide a no-fix report so you can plan next steps.
Emissions & compliance?
We do not modify or disable emissions systems. Our work restores OEM functionality and preserves your calibration. For compliance, ensure your installation and vehicle configuration meet applicable regulations.
Do you support DIY bench instructions or sell tools?
No. We are a professional service lab. This keeps results repeatable and timelines predictable for fleets. If you need guidance on removal/ship-in, we’ll provide a simple checklist.
How should I pack and ship the ECM?
Use anti-static or clean bubble wrap, immobilize in a snug box, and cushion well. Include your info sheet. Avoid foam that sheds particles. Don’t ship installed brackets unless we ask for them.
Warranty terms?
3-month warranty on repairs. It covers the ECM functions we serviced. Physical damage, water ingress, connector/harness faults, or unrelated vehicle issues are not covered. If something seems off after install, contact us first—we’ll help verify quickly.
Pricing, quotes, and fleet accounts?
Pricing depends on platform and condition. For fleet accounts or batch projects, reach out on the contact page—share quantities, timelines, and platforms so we can stage and quote appropriately.
Nationwide coverage—do you serve my location?
Yes. We serve all U.S. states via mail-in (owner-operators to national fleets). We coordinate shipping windows and return options (including overnight) to minimize downtime.
Data integrity & privacy?
Your configuration and calibration data are handled securely and used only to perform repair/cloning and validation. We do not share customer data.
