id0140a5102200

## Operation Condition

• When the ignition switch is turned to the ON position, the PCM turns the fuel pump relay on for 1 s, then off.
• When it is detected that the NE signal rises during cranking, the fuel pump relay turns on.
• When the engine is stopped, the fuel pump relay turns off.

## Operation Inhibition Condition

• When receiving an engine stop request signal from the immobilizer system, the PCM force-stops control of the fuel injectors. As a result, the engine does not start.
