Send Us Your ESN and VIN — We Program The Module Before It Ships
This ECM does not reach you blank. We program it in-house to match your specific engine, so it arrives ready to install with no flashing needed on your side. Our 1–3 business day dispatch window starts from the moment we receive your complete engine information, not from the order date. The sooner you send it, the sooner your module ships.
Please send the following after checkout:
- Engine Serial Number (ESN)
- Vehicle Identification Number (VIN) / machine serial number
- A clear photo of the part number label on your current ECM
- A clear photo of the engine data plate
Installation Notes: We recommend having an experienced heavy-equipment technician fit this module. Always disconnect the battery first, inspect both harness connectors for corrosion or bent pins before plugging in, and clear stored fault codes with your service tool once the new ECM is installed.

Common Failure Symptoms
| Symptom | What It Usually Points To |
|---|---|
| MT765 or 330C engine cranks but will not start | ECM not firing the injectors, or an internal driver circuit failure |
| Engine stalls or shuts down at random under load | Intermittent internal ECM fault, or a loose connector or ground |
| Engine speed hunts or throttle response is erratic | ECM mis-reading inputs, or a faulty throttle / speed sensor |
| Service tool cannot connect to or read the ECM | No power or ground reaching the ECM, a data link fault, or a failed module |
| Many unrelated fault codes appear at the same time | Unstable ECM supply voltage or an ECM that is failing internally |
| Engine runs, then will not restart once it is hot | Heat-related failure of an internal ECM component |
| Green or white corrosion on the ECM connector pins | Water intrusion that may have damaged the circuit board |
| Machine stays in derate or low power with no sensor fault found | ECM logic or configuration fault |
Check the Simple Causes First: Before replacing the ECM, test battery voltage, clean and tighten the ground straps, and inspect the harness and connectors for damage or moisture. These cheaper faults cause many of the same symptoms.
