Toyota RAV4 Service Manual: On-vehicle inspection
- Inspect refrigerant pressure with manifold gauge set
- This method uses a manifold gauge set to locate problem areas. Read the manifold gauge pressure when these conditions are established. Test conditions:
- Temperature at the air inlet is 30 to 35°c (86 to 95°f).
- Engine is running at 1,500 rpm.
- All doors are fully open.
- Blower speed control switch is at hi.
- A/c switch is on.
Gauge readings (reference).
- Normally functioning refrigeration system
Gauge reading v
- The a/c system periodically changes between normal and improper function due to moisture in the refrigerant system.
- The a/c system does not function effectively due to insufficient cooling.
- The a/c system does not function effectively due to poor circulation of the refrigerant.
- The a/c system does not function intermittently because the refrigerant does not circulate.
- The a/c system does not function effectively due to overcharged refrigerant or insufficient cooling of the condenser.
- The a/c system does not function due to air in the refrigeration system.
Caution:
The low-pressure piping may be very hot and cause serious burns.
- The a/c system does not function effectively due to an expansion valve malfunction.
- The a/c system does not function due to a defective compressor.

Different diameter tire malfunction
Description
The skid control ecu measures the speed of each wheel by receiving signals
from the speed sensor.
These signals are used for recognizing that all 4 wheels are operating properly.
Therefore, all wheel
signals must be equal.

Wheels
If a wheel is bent, cracked or heavily corroded, it should be
replaced. Otherwise, the tire may separate from the wheel or
cause a loss of handling control.
Wheel selection
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter ...
