## 🔌 Function

Reads the engine's sensors and controls fuelling and related functions to its programmed settings, keeping the engine running to specification.

## ⚠️ Common Signs of Failure

-   Engine will not start, or cuts out with no fuel or air fault found
-   Warning lamps or alarms with codes pointing at the control unit itself
-   Erratic running or a hard-limited rev ceiling
-   Unit will not communicate with diagnostic equipment
-   Water ingress or corrosion visible in the connector or case

## 🛠️ Service Notes

-   This one is marked Kamd, while control unit 3819874 is marked Kad - the two carry different settings, so ordering the wrong one gives an engine that runs to the wrong specification
-   The superseded number was catalogued as a dataset, so a control unit and its programming may be quoted as separate things in older records
-   Check the supply, earth and connector condition before condemning a control unit, as a poor earth mimics an internal fault
