Leakage Inspection
1. Perform the following tester (evaporative emission system tester (134-01049A)) self-test:
NOTE:
If the tester does not work correctly during self-test, refer to the tester operators manual for more detailed procedures.
a. Verify that the gas cylinder valve is closed and the control valve located on the tester is in the TEST position. All tester displays should be off at this time.
b. Connect the long hose (part of tester) to the tester.
c. Connect the manifold assembly (part of tester) to the long hose as shown.
d. Open the gas cylinder valve and verify the gas cylinder regulator left gauge reads 69—82 kPa {0.71—0.83 kgf/cm2, 10—12 psi}
(preset at factory).
If not, refer to the tester operators manual to contact tester manufacturer.
e. Press the ON/OFF switch to turn on the SST
and make sure the left display reads 0.0
.
f. Turn the control valve on the tester to the FILL position.
g. Verify the left display reading is within 13.9
to 14.0
in of water.
If not, adjust the pressure using the regulator knob located on the right side of the tester.
h. Turn the control valve to TEST position and press the START switch.
i. After the 2-min
countdown (left display) is completed, the right display shows the total pressure loss for that period. A 0.5
in of water loss is acceptable on the self-test.
If the loss is more than tester0.5
in of water, do one or more self-test. If the failed test repeats, check for leak using the ultrasonic leak detector (part of tester).
2. Press the RESET switch to set the left display reading to 0.0.
3. Connect the fuel cap receiver assembly (part of tester) to the manifold assembly and fuel-filler cap from the vehicle.
If the fuel-filler cap is not a genuine part, replace it.
4. Turn the control valve to the FILL position.
5. Wait (maximum 20 s
) until the left display reads 13.9
to 14.0
in of water.
If the reading is slightly below the specification, adjust it using the regulator knob.
If the reading is far below, the fuel-filler cap has a leak. Replace it.
6. Turn the control valve to the TEST position and press the START switch.
7. After the 2-min
countdown (left display) is completed, check the test result (the failed/passed light on the tester).
If the green light turns on, the fuel-filler cap is normal.
If the red light turns on, the fuel-filler cap has a leak. Replace it.
8. Close the gas cylinder valve.
9. Turn the control valve to the FILL position.
10. Press the ON/OFF switch to turn off the tester.
Brake Fluid Pressure Sensor
Purpose/Function
The brake fluid pressure sensor detects the fluid pressure from the master
cylinder and transmits it to the DSC HU/CM.
Construction
The brake fluid pressure sensor is built into the DSC HU/CM. Therefore if
there is any malfunction of the brake fluid pressur ...
Piston, Piston Ring, Piston Pin
Purpose, Function
Piston
The piston in the cylinder of the cylinder block moves reciprocally by the
pressure received when the air-fuel mixture combusts.
Piston ring
The piston ring consists of the compression ring (top ring, second ring)
and the oil ring, and has the foll ...
Differential Oil Replacement
1. Place the vehicle on level ground.
2. Remove the filler plug.
3. Remove the drain plug and drain the differential oil into a container.
4. Install a new washer and the drain plug, and tighten.
Tightening torque
40—53 N·m {4.1—5.4 kgf·m, 30—39 ft·lbf}
5. Add the ...
