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.

Shift position purpose
*1: Shifting the shift lever to d allows the system to select a gear suitable
for
the driving conditions.
Setting the shift lever to d is recommended for normal driving.
