FUEL DRAINING PROCEDURE [SKYACTIV-G 2.5T]

id0114q4853500

Warning

•  Highly pressurized fuel may spray out if the fuel line is cut. Due to the following dangers occurring with a fuel spray, always complete the “Fuel Line Safety Procedure” to prevent the fuel from spraying.

?  Fuel may cause irritation if it comes in contact with skin and eyes.

?  If fuel ignites and causes a fire, it may lead to serious injury or death, and damage to property and facilities.

•  A person charged with static electricity could cause a fire or explosion, resulting in death or serious injury. Before performing work on the fuel system, discharge static electricity by touching the vehicle body.

Fuel Siphoning Procedure Using Fuel Pump

Caution

•  Disconnecting/connecting the quick release connector without cleaning it may possibly cause damage to the fuel pipe and quick release connector. Always clean the quick release connector joint area before disconnecting/connecting using cloth or soft brush, and make sure that it is free of foreign material.

1.  Complete the “BEFORE SERVICE PRECAUTION”. (See BEFORE SERVICE PRECAUTION [SKYACTIV-G 2.5T].)

2.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

3.  Disconnect the quick release connector shown in the figure. (See QUICK RELEASE CONNECTOR REMOVAL/INSTALLATION [SKYACTIV-G 2.5T].)

4.  Connect a long hose to the disconnected quick release connector and drain the fuel into a container used for collecting gasoline.

5.  Drain the fuel from the fuel tank using the following procedure:

Using M-MDS

1.  Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2.  Connect the M-MDS to the DLC-2.

3.  Using the simulation function “FP”, start the fuel pump. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5T)].)

?  If the fuel pump cannot be operated, remove the fuel using the procedure in the reference. (See Fuel Siphoning Procedure Not Using Fuel Pump.)

Without using M-MDS

1.  Remove the fuel pump relay.

Caution

•  Short the specified terminals because shorting the wrong terminal of the relay and fuse block may cause malfunctions.

2.  Using a jumper wire, short fuel pump relay terminals C and D in the relay and fuse block.

3.  Connect the negative battery terminal and operate the fuel pump. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

?  If the fuel pump cannot be operated, remove the fuel using the procedure in the reference. (See Fuel Siphoning Procedure Not Using Fuel Pump.)

Caution

•  The fuel pump could be damaged if it is operated while there is no fuel in the fuel tank. Verify the amount of fuel being discharged from the hose and stop operation of the fuel pump when essentially no fuel is being discharged.

6.  Stop the fuel pump using the following procedure.

Using M-MDS

1.  Using the simulation function “FP”, stop the fuel pump. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5T)].)

2.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

Without using M-MDS

1.  Remove the jumper wire to stop the fuel pump.

2.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

Fuel Siphoning Procedure Not Using Fuel Pump

1.  Complete the “BEFORE SERVICE PRECAUTION”. (See BEFORE SERVICE PRECAUTION [SKYACTIV-G 2.5T].)

2.  Remove the fuel pump unit. (See FUEL PUMP UNIT REMOVAL/INSTALLATION [SKYACTIV-G 2.5T].)

3.  Remove the fuel gauge sender unit (sub). (4WD) (See FUEL GAUGE SENDER UNIT REMOVAL/INSTALLATION [4WD].)

4.  Drain the fuel in the tank from the unit installation hole.
