SFI SYSTEM

FUNCTION

1. EURO V Models

   
   

   1. The fuel pump is controlled by the ECM, using the fuel pump control ECU assembly. Fuel pump control has fuel cut control. Fuel cut control stops the fuel pump when any of the Supplemental Restraint System (SRS) airbags have deployed.

2. EURO IV Models

   
   

   1. In this system, the airbag deployment signal from the airbag sensor assembly is detected by the ECM, and turns off the circuit opening relay. After fuel cut control has been activated, turning the ignition switch from off to ON cancels fuel cut control, and the engine can be restarted.
