## ⚙️ Key Features

-   Engine-to-PCU cable
-   Length: 3.0 metres
-   Factory-moulded EVC connectors
-   Carries power, control and network signals
-   Documented in D11A and transmission connecting-kit installations

## 🔌 Function

The cable links the engine electronics with the PCU and carries the signals required for engine and transmission control.

## ⚠️ Common Signs of Failure

-   Intermittent EVC communication
-   Engine or gear-control alarms
-   No response from connected control equipment
-   Fault changes when the cable is moved
-   Chafed or water-damaged cable

## 🛠️ Service Notes

-   Isolate the battery before disconnecting or reconnecting anything, and make sure connectors are clean, dry and fully latched before switching the system back on
-   Route the new cable along the original path and secure it with the original clips, ties and stand-offs; unsupported cable chafes through wherever it touches a bracket, hose or edge
-   Keep the run clear of the exhaust and turbocharger, away from moving parts and sharp edges, and use a grommet or gland wherever it passes through a panel or bulkhead
-   Protect the connections against damp — a properly seated and sealed connector survives an engine bilge atmosphere far better than a taped joint
-   Replace a damaged cable rather than patching it; where a repair is unavoidable use a crimped and sealed joint, never solder as the only mechanical connection
