ADD COMPRESSOR OIL
When performing work on air conditioning parts, follow the oil guidelines below in order to protect the cooler compressor.
| Part and Condition | Oil Level (cc) | Work Procedure | |
|---|---|---|---|
| Compressor replacement | -100 to -120 | Drain oil from new compressor | |
| Condenser replacement | 35 to 55 | Fill oil into replacement part | |
| Evaporator replacement | 40 to 60 | ||
| A/C pipe replacement | High pressure | 5 to 25 | |
| Low pressure | |||
| When discharging refrigerant gas quickly | 30 to 50 | While applying vacuum, use manifold gauge to fill oil from low pressure side valve | |
CHARGE REFRIGERANT
Perform vacuum purging using a vacuum pump.
Charge refrigerant HFC-134a (R134a).
| Standard | |||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
|
| *a | Amount to be charged | *b | Charge 100 g (3.53 oz) |
| *c | Mean value in proper range | *d | Point where bubbles disappear |
| *e | Overcharged | *f | Pressure |
| *g | Sub-cool system | *h | Refrigerant amount |
Note
Do not operate the cooler compressor before charging refrigerant as the cooler compressor will not work properly without any refrigerant, and will overheat.
Approximately 200 g (7.05 oz.) of refrigerant may need to be charged after bubbles disappear. The refrigerant amount should be checked by measuring its quantity, and not with the sight glass.
WARM UP ENGINE
Warm up the engine at less than 1850 rpm for 2 minutes or more after charging the refrigerant.
Note
Be sure to warm up the compressor when turning the A/C switch ON after removing and installing the cooler refrigerant lines (including the compressor) to prevent damage to the compressor.
CHECK FOR LEAKAGE OF REFRIGERANT
After recharging the refrigerant gas, check for refrigerant gas leakage using a halogen leak detector.
Perform the operation under these conditions:
Stop the engine.
Secure good ventilation (the halogen leak detector may react to volatile gases other than refrigerant, such as evaporated gasoline or exhaust gas).
Repeat the test 2 or 3 times.
Make sure that some refrigerant remains in the refrigeration system.
Tech Tips
When compressor is off:
approximately 392 to 588 kPa (4 to 6 kgf/cm2, 57 to 85 psi)
| *1 | Halogen Leak Detector |
| *a | Check for Leakage |
Using a halogen leak detector, check the refrigerant line for leakage.
If a gas leak is not detected on the drain hose, remove the blower motor control (blower resistor) from the cooling unit. Insert the halogen leak detector sensor into the unit and perform the test.
Disconnect the connector and wait for approximately 20 minutes. Bring the halogen leak detector close to the pressure switch and perform the test.
ADJUST MILLIMETER WAVE RADAR SENSOR ASSEMBLY (w/ Dynamic Radar Cruise Control System)
CAUTION:
Exposure to radio frequency emissions is hazardous to your health. It is hazardous to be within 20 cm (7.87 in.) of the device's radio frequency aperture.
Note
This device complies with FCC radio frequency emission regulations.
Perform measurements on a level surface.
Make sure that no large pieces of metal are within a 10 m (32.8 ft.) x 14 m (45.9 ft.) area in front of the vehicle. If possible, the surrounding area should also be free of large metal objects.
Before adjusting the radar beam axis, prepare the vehicle as follows.
Check the tire pressure and adjust it if necessary.
Remove all excess weight from the vehicle (luggage, heavy objects, etc.).
w/ Air Suspension:
Adjust the vehicle's height to the standard height.
Check and adjust the vertical direction of the radar sensor.
Remove dust, oil and foreign matter from the radar sensor's level rack.
Set a level on the radar sensor's level rack.
Check that the level's air bubble is within the red frame.
| OK |
|---|
| Level's air bubble is within red frame. |
If the bubble is not within the red frame, use a hexagon wrench to adjust bolt A until the level's air bubble is within the red frame.
Tech Tips
The adjustable range within the red frame of the level is +/-0.2°.
The target angle is +0.2° (upward angle of 0.2°).
| Adjustment Direction | Adjustment Procedure | Adjustment Angle |
|---|---|---|
| Vertical adjustment |
|
For 1 complete turn of screwdriver, sensor moves about 0.12° |
Adjust the reflector height.
Adjust the reflector so that the center of the SST reflector is the same height as the millimeter wave radar sensor.
Tech Tips
Prepare a 10 m (32.8 ft.) string with a sharp-pointed weight (plumb bob) and a 5 m (16.4 ft.) tape measure.
Place the reflector.
From the center of the front bumper (center of the emblem), hang a weight with a pointed tip, and mark point B on the ground.
From the center of the rear bumper (center of the emblem), hang a weight with a pointed tip, and mark point A on the ground.
Using a piece of string that uses point A as a starting point and that passes through point B, make a straight line on the ground ahead of the vehicle 5 m (16.4 ft.) or more from point B.
Tech Tips
Make sure to secure the string (using tape, etc.) when it is taut.
Lightly flick the string with your fingers several times to confirm that the string is aligned above point B.
Using a tape measure, measure 10 mm (0.394 in.) to the left of the 5000 mm (16.4 ft.) position. Place the reflector at that position.
Note
Perform the operation as precisely as possible.
Check the radar beam axis.
When using the intelligent tester:
Connect the intelligent tester to the DLC3.
Turn the engine switch on (IG).
Turn the intelligent tester main switch ON and turn the cruise control main switch ON.
Select "Auto" from the intelligent tester display screen. *1
Select "Radar Cruise" from the display screen.
Select the appropriate menu item.
For vehicles with lane recognition camera: select "w/ LKA System" from the display screen.
For vehicles without lane recognition camera: select "w/o LKA System" from the display screen.
Select "Radar Cruise" from the display screen.
Select "Utility" from the display screen.
Select "Beam Axis Adjustment" from the display screen.
Select "Next".
Select "Next".
Select "Next".
Note
Turn the cruise control main switch ON before pressing Next.
Make sure there is a distance of at least 20 cm (7.87 inches) between the radar sensor and any nearby individuals.
CAUTION:
Do not come within 20 cm (7.87 inches) of the radar sensor.
Check the following items on the laser cruise divergence data screen.
CAUTION:
While using the intelligent tester's beam axis adjustment mode, the actual direction and angle of the radar sensor may be different from the intelligent tester's data. In such a case, the deviation is displayed on the combination meter's multi-information display.
Confirm that the distance value is approximately 5 m (16.4 ft.).
Tech Tips
A value between 0.0 and 6.3 m (20.7 ft.) is indicated.
If the distance is 0 m (0 ft.), the sensor cannot detect the target. Reconfirm that there is no metal in the specified area in front of the vehicle (refer to the NOTICE at the beginning of this adjustment procedure).
Confirm that the left/right side value is between 0.0 and 6.3°.
Tech Tips
If the distance is 0 m (0 ft.), the sensor cannot detect the target. Reconfirm that there is no metal in the specified area in front of the vehicle (refer to the NOTICE at the beginning of this adjustment procedure).
Check and adjust the horizontal direction of the radar sensor.
Check that the divergence of the radar beam axis is 0°.
| Standard |
|---|
| 0° (Both right and left) |
If the axis is not as specified, use a hexagon wrench to adjust bolt B until the divergence of the radar beam axis is 0°.
Based on the measured divergence of the beam axis, turn and adjust bolt B for horizontal adjustment of the millimeter wave radar sensor using a hexagon wrench.
| Adjustment Direction | Adjustment Procedure | Adjustment Angle |
|---|---|---|
| Horizontal adjustment |
