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

Initial symptoms of a failing control unit include intermittent engine stalling, rough idling, or a lack of throttle response. If left unaddressed, these issues can escalate to persistent engine misfires, inability to start, or critical system failures. Continued operation risks significant downtime and potential damage to other engine components.

Installation Tip

Ensure the battery is disconnected and all electrical loads are off before attempting to remove or install the control unit to prevent electrical surges. Never attempt to open the sealed unit, as this will void any warranty and likely cause irreparable damage.

Service Note

Inspect the engine wiring harness and all related sensor connections for any signs of corrosion, damage, or loose connections before installing a new control unit.
