Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Early signs of failure include intermittent engine performance issues, such as rough idling or hesitation. If the problem persists, the engine may stall unexpectedly or refuse to start, often accompanied by diagnostic trouble codes. Complete failure of the control group will render the engine inoperable.

Installation Tip

Before installing the new control group, disconnect both battery terminals to prevent electrical surges. Ensure all electrical connectors are clean and securely seated to guarantee proper communication with engine sensors.

Service Note

Inspect all engine sensors, wiring harnesses, and the battery charging system for faults when replacing the electronic control group.
