WARNING:
Fuel line spills and leakage from the pressurized fuel system are dangerous. Fuel can ignite and cause serious injury or death and damage. To prevent this, complete the following inspection with the engine stopped.
Fuel is very flammable liquid. If fuel spills or leaks from the pressurized fuel system, it will cause serious injury or death and facility breakage. Fuel can also irritate skin and eyes. To prevent this, always complete the “Fuel Line Safety Procedure”, while referring to the “BEFORE SERVICE PRECAUTION”.
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.
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”..
2. Disconnect the negative battery cable..
3. Disconnect the quick release connector as shown in the figure..
4. Turn the lever of the SST
parallel to the hose as shown in the figure.
5. Insert the SST
quick release connector into the fuel pipe until a click is heard.
6. Verify that the quick release connector is firmly connected by pulling it by hand.
7. Start the fuel pump using the following procedure.
Connect the negative battery cable..
Connect the M-MDS to the DLC-2.
Using the simulation function “FP”, start the fuel pump..
Remove the fuel pump relay.
CAUTION:
Short the specified terminals because shorting the wrong terminal of the relay and fuse block may cause malfunctions.
Using a jumper wire, short fuel pump relay terminals C and D in the relay and fuse block.
Connect the negative battery cable and operate the fuel pump..
8. Operate the fuel pump for 10 s
.
9. Measure the fuel line pressure.
If not within the specification, inspect the following:
Fuel pump unit
Fuel line for restriction or leakage
Fuel line restriction
405—485 kPa {4.13—4.94 kgf/cm2, 58.8—70.3 psi}
10. Stop the fuel pump using the following procedure.
Using the simulation function “FP”, stop the fuel pump..
Disconnect the negative battery cable to stop the fuel pump..
11. Measure the fuel hold pressure after 5 min
.
If not within the specification, inspect the following:
Fuel line leakage
230 kPa {2.35 kgf/cm2, 33.4 psi} or more
12. Complete the “BEFORE SERVICE PRECAUTION”..
13. Disconnect the SST
.
14. Connect the quick release connector..
15. Complete the “AFTER SERVICE PRECAUTION”..
A/C Unit Removal/Installation
1. Disconnect the negative battery cable..
2. Discharge the refrigerant..
3. Drain the engine coolant..
CAUTION:
If moisture or foreign material enters the refrigeration cycle, cooling ability
will be lowered and abnormal noise or other malfunction could occur. Always
