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

An engine that starts intermittently or fails to start altogether, accompanied by multiple dashboard warning lights, are common signs of ECU failure. The engine may also run poorly, with unexpected power loss or stalling. A completely failed ECU will prevent the engine from running at all, immobilizing the vehicle.

Installation Tip

Ensure the battery voltage is stable and disconnected before removing the old ECU to prevent electrical surges. Never attempt to program an ECU without the correct diagnostic tools and software.

Service Note

Before replacing the ECU, thoroughly check all engine sensors and wiring harnesses for faults, as a faulty sensor can sometimes mimic ECU failure.
