Product Details
This Engine Control Module (ECM / ECU) is an Remanufactured replacement for Caterpillar part number 10R-4093 ECM (10R4093), used on C9 engines in 627G / 637G wheel scrapers, D6R II track-type tractors, 330C-series excavators, TK700-series track feller bunchers and MT700-series track tractors.
During remanufacturing the circuit board is inspected under magnification, failed or heat-stressed components are replaced, and the housing seals and connector pins are checked for moisture damage. Every module is then powered up on a test bench to confirm it restores original operating parameters.

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: Installation and removal by an experienced heavy-equipment technician is strongly recommended. Disconnect the battery before unplugging or connecting the ECM, check the harness connectors for bent pins or moisture, and clear any stored fault codes with your service tool after installation.

Common Failure Symptoms
| Symptom | What It Usually Points To |
|---|---|
| 627G / 637G scraper engine cranks but will not start | ECM not firing the injectors, or an internal driver circuit failure |
| Warning lamp stays on at key-on and no codes can be read | ECM failing to power up or boot correctly |
| Engine stalls or shuts down at random under load | Intermittent internal ECM fault, or a loose connector or ground |
| Service tool cannot connect to or read the ECM | No power or ground reaching the ECM, a data link fault, or a failed module |
| Machine stays in derate or low power with no sensor fault found | ECM logic or configuration fault |
| One cylinder misfires and swapping the injector does not fix it | A failed injector driver inside the ECM, or damaged injector wiring |
| Green or white corrosion on the ECM connector pins | Water intrusion that may have damaged the circuit board |
| Engine runs, then will not restart once it is hot | Heat-related failure of an internal ECM component |
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.
