Kubota V3800DI-T Diesel Engine ECU (Replaced by 1J419-60604) | Genuine Kubota 1J419-60603
This is a new, genuine Kubota engine control unit (ECU), part number 1J419-60603. It belongs to Kubota’s 1J419 engine series, a V3800DI-T direct-injection turbo diesel with a mechanical in-line injection pump. It is not the ECU of the V3800 common-rail engines, which use a larger ECU sub-assembly under other numbers.
It replaces 1J419-60600 and 1J419-60602, and Kubota has since moved this ECU to a newer number, 1J419-60604. A shutdown or a no-start is not always the ECU, so rule out the sensors, the switches, the wiring, the grounds and battery voltage before you replace it.
Confirm Fitment Before You Order
An ECU has to match the engine, by engine serial number and by build. This one is for the mechanical-pump V3800DI-T in Kubota’s 1J419 series, not for V3800 common-rail engines, which use a different ECU sub-assembly. Kubota’s current number for this ECU is 1J419-60604: if your old ECU is marked 1J419-60600, 1J419-60602 or 1J419-60603, this is the direct replacement, and if it is marked 1J419-60604, call us first, because a newer number does not always go back to an older one. Send us the engine model, the engine serial number and the number on your old ECU. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.

Disconnect the battery before you unplug the ECU. Test the sensors, the switches and their harnesses before you condemn the ECU. Check the connector pins, the grounds and battery voltage, since the fault that damaged the old unit can damage the new one. After the swap, run the engine under load and check that it holds its rated speed.
