⚙️ 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
