13 -FUEL > 13A-DIRECT INJECTION AND MULTIPOINT FUEL INJECTION (DI AND MPI) > ON-VEHICLE SERVICE > FUEL PUMP CONNECTOR DISCONNECTION (HOW TO REDUCE PRESSURIZED FUEL PRESSURE)
warningWhen removing the fuel pipe, etc., release fuel pressure to prevent fuel spray.
 
 
<Low pressure side>
1. Remove the rear seat assembly (Refer to GROUP 52A - Rear Seat Assembly ) and turn up the floor carpet.
 
2. Remove the floor inspection lid (LH).
 
3. Disconnect the fuel pump and gauge assembly connector.
4. Crank the engine for at least two seconds.
5. If the engine is not started, turn the ignition switch to the "LOCK" (OFF) position.
6. If the engine is started, turn the ignition switch to the "LOCK" (OFF) position after the engine stopped.
7. Connect the fuel pump and gauge assembly connector.
8. Install the floor inspection lid (LH).
9. Return the floor carpet to the original condition and install the rear seat assembly (Refer to GROUP 52A - Rear Seat Assembly ).
 
 
 
<High pressure side>
cautionTo prevent damage to the M.U.T.-IIISE, always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting the M.U.T.-IIISE.
1. Connect the M.U.T.-IIISE to the diagnosis connector.
2. Start the engine and run at idle.
3. Check "Item No. 124: Fuel rail pressure sensor (Absolute)" from the M.U.T.-IIISE data list.
4. When the data list item 124 reaches approximately 4 MPa, turn the ignition switch to "LOCK" (OFF) position and wait until the engine is cool.
5. Disconnect the M.U.T.-IIISE.
cautionCover the hose connection with rags to prevent splash of fuel that could be caused by some residual pressure in the fuel pipe line.
 
6. Cover the connection between the fuel pump (high pressure) and fuel delivery intermediate pipe with a waste cloth.
7. Loosen the fuel delivery intermediate pipe at the fuel pump (high pressure).
