## ⚙️ Key Features

-   Identified as a Com Module
-   0.152 kg
-   22 applications on D series engines
-   Ignition and Control Systems group

## 🔌 Function

Handles communication between the engine's control system and the equipment connected to it, passing data across the bus in both directions.

## ⚠️ Common Signs of Failure

-   Instruments or display losing contact with the engine
-   Communication or bus fault codes logged
-   Readings that freeze at their last value
-   Fault clears when the connector is pushed home, pointing at pins rather than the module
-   Corrosion or moisture inside the connector shell

## 🛠️ Service Notes

-   Check bus wiring, terminations and connector pins before replacing the module - a broken bus reads as a dead module
-   Note the software or configuration requirements of your installation, since a communication module usually has to be recognised by the system it joins
