b. Connect the center hose of the manifold gauge set to the vacuum pump adapter.

c. Open both the high and low hand valves and run the vacuum pump.

d. After 10 minutes or more, check that the low pressure gauge indicates 750 mmHg (30 in. Hg) or more.

NOTE: If the reading 750 mmHg (30 in. Hg) or more, close both hand valves of manifold gauge set and stop the vacuum pump.

Check the system for leaks and repair necessary.

e. Close both the high and low hand valves and stop the vacuum pump.

f. Leave the system in this condition for 5 minutes or more and check that there is no change of gauge indicator.

2. INSPECT REFRIGERATION SYSTEM FOR LEAKS

a. Open the high pressure hand valve and charge refrigerant.

b. When the low pressure gauge indicates 98 kPa (1 kgf/cm2 , 14 psi) close the high pressure hand valve.

c. Using a gas leak detector, check the system for leakage.

CAUTION: Use the refrigerant recovery/ recycling machine to recover the refrigerant whenever replacing parts.

3. CHARGE REFRIGERANT INTO REFRIGERANT SYSTEM

2004 HVAC Air Conditioning System - Sequoia

If there is no leak after refrigerant leak check, charge the proper amount of refrigerant into refrigeration system.

CAUTION: • Never run the engine when charging the system through the high pressure side.

• Do not open the low pressure hand valve when the system is being charged with liquid refrigerant.

a. Open the high pressure hand valve fully.

b. Charge specified amount of refrigerant, then close the high pressure hand valve.

NOTE: A fully charged system is indicated by the sight glass being free of any bubbles.

c. Charge partially refrigeration system with refrigerant.

1. Set vehicle in these condition:

• Running engine at 1,500 RPM

• Front blower speed control dial at "HI" position

Front and rear blower speed set at "HI" position

Front temperature control dial at "MAX. COOL" position

Front temperature control dial at "MAX. COOL" position Rear temperature control set at 18.5 °C (65°F)

• Air inlet control set at "RECIRC"

• Fully open doors (Sliding roof: closed)

2. Open the low pressure hand valve.

CAUTION: Do not open the high pressure hand valve.

INSPECTION

2004 DRIVELINE/AXLES A.D.D. Control System - Sequoia

1. INSPECT A.D.D. ACTUATOR

a. Disconnect the actuator connector.

b. Measure the resistance between the terminals 2 and 6.

Standard resistance: 0.3 - 100 ohm c. Measure the resistance between the terminals 2 or 6 and body ground. Standard resistance: More than 0.5 Mohm

If the resistance value is not as specified, replace the actuator assembly.
