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

A failing ECU may initially manifest as intermittent engine warning lights or minor performance glitches like rough idling. If left unaddressed, these issues can escalate to persistent engine misfires, inability to start the engine, or complete loss of communication with the diagnostic system. Ignoring ECU faults risks significant drivability problems and potential damage to other engine components.

Installation Tip

Always disconnect the battery before attempting to replace the ECU to prevent electrical surges. Ensure the new ECU is properly secured in its mounting location to avoid vibration damage.

Service Note

After installing a new ECU, it is essential to perform a diagnostic scan to clear any old fault codes and program the unit for the specific vehicle and engine configuration.
