Purpose, Function
Supplies fuel in the fuel tank to the high pressure fuel pump.
Based on the control signal from the PCM, the fuel pump operates by the operation of the fuel pump relay and the fuel pump control module.
Construction
2WD
The fuel pump unit is installed to the fuel tank.
The fuel pump unit consists of a fuel pump, fuel filter (low-pressure) fuel filter (high-pressure), pressure regulator, and lower cover.
AWD
The fuel pump unit is installed to the fuel tank.
The fuel pump unit consists of a fuel pump, fuel filter (low-pressure) fuel filter (high-pressure), pressure regulator, lower cover, and jet pump.
Operation
2WD
Based on the control signal from the PCM, the fuel pump suctions fuel in the lower cover and pumps it to the high pressure fuel pump. After fuel is sufficiently filtered through the fuel filter (low-pressure) and fuel filter (high-pressure), fuel pressure is adjusted to approx. 430 kPa {4.38 kgf/cm2, 62.4 psi}
by the pressure regulator.

by the pressure regulator.
Positions the venturi pipe (jet pump) in the return path from the pressure regulator and sends fuel from the fuel tank sub side to the main side using vacuum generated in that area.

Rear Body Control Module (Rbcm) Configuration (Using Read/Write Function)
NOTE:
When performing configuration, it is necessary to read the vehicle specification
information from the rear body control module (RBCM) before replacing it. Connect
the M-MDS to the vehicle and perform vehicle identification before removing
the rear body control module (RBCM). T ...
Dynamic Stability Control (DSC)
The Dynamic Stability Control (DSC) automatically controls braking and engine
torque in conjunction with systems such as ABS and TCS to help control side slip
when driving on slippery surfaces, or during sudden or evasive maneuvering, enhancing
vehicle safety.
Refer to ABS and TCS .
