| Fault Code Description |
|---|
|
This entry does not describe a fault in the refrigerant circuit. Instead it documents that a heating and air conditioning function has been restricted due to the 12 V vehicle electrical system not being properly charged. Depending on the condition of the 12 V vehicle electrical system, the following components may have impaired functioning: BlowerRear window heatingElectric auxiliary heater As soon as the 12 V vehicle electrical system is sufficiently charged again, the restriction is automatically cancelled. |
| Fault Code Conditions | |
|---|---|
| General Conditions |
Supply voltage between 9 and 16.5 volts. |
| Terminal Condition |
Terminal 15 on |
| Driving Conditions | |
| Fault Time Condition |
|---|
|
The respective restriction is enabled whenever the system detects that the 12 V vehicle electrical system is not sufficiently charged. |
| Service Plan |
|---|
|
Run the test module for reducing power consumption of electrical equipment. |
| Fault Impact |
|---|
|
Restricting climate control whenever the 12 V vehicle electrical system is insufficiently charged guarantees reliable starting of the combustion engine. |
