Toyota RAV4 (XA40) 2013-2018 Service Manual: Precaution
- If any of following conditions are met, keep engine idling with a/c on (engine speed at less than 2000 rpm) for at least 1 minute:
- Refrigerant gas has been refilled or a/c parts have been replaced.
- A long time has elapsed since the engine was stopped.
Notice:
If the engine speed exceeds 2,000 rpm, the a/c compressor may be damaged.
- Do not handle refrigerant in enclosed areas or near open flames
- Always wear eye protection
- Be careful not to get liquid refrigerant in your eyes or on your skin
If liquid refrigerant gets in your eyes or on your skin:
- Wash the area with lots of cold water.
Caution:
Do not rub your eyes or skin.
- Apply clean petroleum jelly to the skin.
- Go immediately to a physician or hospital for professional treatment.
- Never heat container or expose it to open flame
- Be careful not to drop container or subject it to physical shocks
- Do not operate compressor with insufficient refrigerant in refrigerant system
If there is not enough refrigerant in the refrigerant system, oil lubrication will be insufficient and compressor burnout may occur. Necessary care should be taken to avoid this.
- Do not open high pressure manifold valve while compressor is operating
Open and close only the low pressure valve. Opening and closing the high pressure valve could cause the charging cylinder to rupture.
- Be careful not to overcharge system with refrigerant
If the refrigerant is overcharged, it causes problems such as insufficient cooling, poor fuel economy and engine overheating.
- Do not operate engine and compressor without refrigerant
Notice:
This may damage the inside of the compressor.

Pressure sensor circuit
Description
This dtc is output when the refrigerant pressure is either extremely low
(0.19 Mpa [2.0 Kgf/cm2, 28 psi]
or less) or extremely high (3.14 Mpa [32.0 Kgf/cm2, 455 psi] or more). The air
conditioning pressure
sensor, which is installed on the pipe of the high pressure side, detec ...
Short in can bus lines
Description
There may be a short circuit between the can bus lines when the resistance
between terminals 6 (canh)
and 14 (canl) of the dlc3 is below 54
.

Air mix damper control servo motor circuit (passenger side)
Description
The air mix damper servo sends pulse signals to indicate the damper position
to the air conditioning
amplifier. The air conditioning amplifier activates the motor (normal or
reverse) based on these signals to
move the air mix damper (passenger seat) to the appropriate position ...
