CAT 70 pin ECM Repair

Is your Caterpillar down with a no-start, derate, or communication fault on a 70-pin ECM? This is the bench repair service for ADEM III / ADEM A4 style modules with the large 70-pin harness connector — not the older 40-pin 3406E 1LW/2WS units. We replace failed injector drivers, rebuild the power supply section, and refresh the processor and memory so the module can be flashed and returned to service. Typical applications include C10, C12, C15, C16, and many 3406E / ACERT-era engine control modules that use the 70-pin connector and mounting pattern. Every unit is function-tested before shipment. Repairs include a 3 year warranty on workmanship for CAT 70-pin ECMs. Send your core or order repair service below — include engine model, ECM part number, and symptom notes so we match the correct hardware generation.
