t
| A - The pressure in the refrigerant circuit is lower than that indicated in the table (insufficient refrigerant in the circuit). |
- Check for leaks using leak detector. |
- Pressure relief valve open, check that the refrigerant fan activates according to the electrical circuit diagram. |
Check that refrigerant piping and hoses and not bent too much or kinked (narrowing cross-section), and ensure that they are not damaged. If no faults are found, purge the refrigerant circuit. |
t
| B - The pressure in the refrigerant circuit is equal to or higher than that indicated in the table. |
–
| Set air conditioning system for maximum cooling output. |
–
| Open the dash panel vents. |
The compressor is driven by the engine by means of a Poly-V belt and an electromagnetic coupling. |
Note t
| If the air-conditioner compressor is not activated, check the power supply to the air-conditioner electromagnetic coupling -N25- with the electrical circuit diagram. |
t
| If the power supply is correct, repair the electromagnetic coupling. |
If the compressor is driven, check the refrigerant circuit: |
–
| Let the engine run at a speed of 2000 rpm. |
–
| Observe the manifold gauge. |
