⚙️ Key Features

🔌 Function

The cable provides a short network connection between EVC, steering and engine-control components.

⚠️ Common Signs of Failure

• EVC communication fault
• Docking or steering station unavailable
• Intermittent network operation
• Water or corrosion at connectors
• Damaged cable or locking tabs

🛠️ 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
