| Checking pressures on vehicles with a restrictor and reservoir (with internally regulated air conditioner compressor) |
Note | t
| Connect air conditioner service station → Chapter. |
| –
| Check the pressures in the refrigerant circuit (with the air conditioner service station) with the ignition switched off → Chapter. |
| The pressures with the ignition switched off correspond to the specifications. |
| –
| Set engine speed to 2000 rpm. |
| –
| Observe the pressure reading (e.g. pressure gauge) of the air conditioner service station. |
Note | t
| Switching pressures for refrigerant circuit switches are vehicle-specific. |
| t
| The connection with valve for the low-pressure switch or at the evaporator is only to be used for vehicles with no service connection on the low-pressure end and an inaccessible connection at the air conditioner compressor or reservoir (measurement accuracy). Only applies to certain vehicles → Heating, air conditioning; Rep. gr.87 or → Air conditioning; Rep. gr.87 (vehicle-specific workshop manual). |
