| No. | Component(s) concerned | Cause(s) | Consequence(s) |
| 11 | Solar sensor failure | The signal from the solar sensor is out- side its limits or is giving an impossible value. | The system takes a default value of 300 W/m². |
| 14 | Recirculation actuator no. 1 input error | The signal from the potentiometer of recirculation actuator no. 1 is outside its operating range. | The recirculation actuator (no. 1 and 2) is automatically set to the “external air” position. |
| 15 | Potentiometer recirculation actuator (no. 1 & 2) reference error | The potentiometer reference is short circuited to the earth. | The recirculation actuator (no. 1 and 2) is automatically set to the “external air” position. |
| 16 | Input error from selected temperature potentiometer | The signal is outside its operating range. | The system switches to automatic mode at a temperature selected by default (21°C). |
| 17 | Input error from fan speed potentiometer | The signal is outside its operating range. | The system controls the fan speed automatically. |
| 18 | Ambient temperature sensor fan fault | The fan does not turn. | |
| 19 | Stepper motor output error (water valve) | The stepper motor does not operate correctly. | |
| 20 | Recirculation actuator motor (no. 1 and 2) output error | The recirculation actuator does not operate correctly. | The recirculation actuator motor output (no. 1 and 2) is deactivated. |
| 21 | Air conditioning relay output error | The relay does not operate correctly. | |
| 22 | Water pump relay output error | The relay does not operate correctly. | |
| 23 | Fan relay output error | The relay does not operate correctly. | |
|
24 |
Engine speed error |
The CAN message is not valid. | The system considers the last value received within 2 seconds. |
| If no CAN message is received during this time, the system takes a default value of 1500 rpm. | |||
| 25 | Vehicle speed error | The CAN message is not valid. | If no CAN message is received, the system considers the last value received within 2 seconds (20 consecutive mes- sages). |
|
26 |
Engine water temperature error |
The CAN message is not valid. | The system considers the last value received within 10 seconds. |
| If no CAN message is received during this time, the system takes a default value of 90°C. | |||
| 27 | Fan speed controller no. 1 output error | The signal is outside its operating range. | |
| 28 | Failure due to undervoltage | The supply signal is lower than the minimum value. | The control unit operates in degraded mode. |
| 29 | Failure due to overvoltage | The supply signal is higher than the maximum value. | The control unit is deactivated. |
| 30 | Fan speed controller no. 2 output error | The signal is outside its operating range. | |
| 31 | Fan speed controller no. 1 return error | The signal is outside its operating range. | |
| 32 | Fan speed controller no. 2 return error | The signal is outside its operating range. | |
| 33 | Recirculation actuator no. 2 input error | The signal from the potentiometer of re- circulation actuator no. 2 is outside its operating range. | The recirculation actuator (no. 1 and 2) is automatically set to the “external air” position. |
