AC or AC Off Indicator Lamp Flashes After Actuation / Air Conditioning Not Functioning
If you receive customer reports in the above model vehicles of the AC or AC Off indicator lamp flashing and the air conditioning is not operating, the cause could be the coding of the climate system control module. Follow the instructions below to overcome the specification parameter in the refrigerant level logic circuit.
1. Process any fault codes in the climate system and repair as necessary.
2. Confirm refrigerant level by performing a Refrigerant Circuit Test as per SDS and following instructions for corrective actions.
3. Only after steps 1 and 2 are completed, use Star Diagnosis to deactivate the fill level control as per the instructions listed below.
Model 203: Control unit groups --> Body --> EZS - Electronic ignition switch --> Control unit adaptations --> Read coding and change if necessary --> Climate control --> Standard setting: Climate control --> Refrigerant level check --> Set to Inactive
Model 216/221: Main groups --> Control units --> Air conditioning --> AAC - Automatic air conditioning (Interior CAC bus) --> Read coding and change if necessary --> Control unit adaptations --> Workshop coding --> Refrigerant level check --> Set to Deactivated
Model 171, 211 and 219: If the fluid level control is still active, there will be a menu item in 'Main groups' labeled 'Check for necessary coding measures' (Figure 1). Process this menu item to deactivate the coding of the fluid level controls (Figure 2 and 3). If the fluid level control is already inactive, this additional menu item will not appear when "Main groups" is selected (Figure 4).
Note:
If the fluid level control has already been deactivated and the vehicle has the symptoms described, there is a fault that has not been corrected and further diagnosis is necessary. Refer to applicable diagnostic trees in the Vehicle Heating, Ventilation, Air Conditioning (HVAC) Manual found on STAR TekInfo --> EDAC --> Non EDAC Guides.
