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.
The initial symptom of a failing control unit might be an intermittent engine stall or a check engine light. If left unaddressed, the engine may refuse to start, run erratically, or shut down unexpectedly during operation. Continued use with a faulty ECU risks significant downtime and potential damage to other engine components due to improper management.
Always disconnect the battery before removing or installing the control unit to prevent electrical surges. Ensure the electrical connectors are clean and properly seated to maintain a reliable connection.
When replacing the control unit, it is advisable to inspect the engine wiring harness for any signs of damage or corrosion that could affect signal integrity.
