## ⚠️ Common Signs of Failure

-   Engine will not start
-   Intermittent shutdown
-   Communication failure
-   Multiple unrelated diagnostic codes
-   Output to injectors or ignition is lost
-   Internal water or corrosion damage

## 🛠️ Service Notes

-   Isolate the batteries before unplugging or fitting any module, and never disconnect one with the ignition on or the engine running
-   Before condemning a module, check its supply, its earth and the harness continuity; a poor earth or a chafed lead gives exactly the same symptoms as a dead unit
-   Handle the module by its casing, keep the connector pins clean and dry, and push connectors home squarely until the lock engages — bent or corroded pins cause more trouble than the modules themselves
-   Mount it in the original position and orientation using the original brackets or clips, so it stays clear of heat, moving parts and standing water
-   Many engine and control modules have to be configured or programmed to your particular engine before they will work correctly, so allow for a Volvo Penta dealer with the correct diagnostic equipment where that applies
