Was bedeutet der Fehlercode?
On cars with electronic climate control (ECC), the control module has received too high a signal from the sun sensor. Since the sensor does not give a usable value, the control module instead works from a stand-in value for solar load, so the cabin does not cool properly when the sun is strong.
Mögliche Ursachen
- Contact resistance, oxidation or loose contacts in the connectors
- Open circuit in the signal wire linking the control module to the sun sensor
- Signal wire linking the control module to the sun sensor shorted to live voltage
- Ground wire linking the control module to the sun sensor shorted to live voltage
- Open circuit in the ground wire linking the control module to the sun sensor
- Defective sun sensor
Was Sie tun können
- 1With the ignition on, cover the sun sensor with your hand and check that the value on the climate panel drops
- 2Then hold a strong light, such as a torch, close to the sun sensor and check that the value rises
- 3Check the contacts at the sun sensor and at the control module for looseness, damage or corrosion
- 4Check the wiring for chafing and crushed areas
- 5Use a multimeter to check the signal and ground wires to the sun sensor for contact with live voltage or ground (the body)
- 6If the wiring is fine, have a workshop replace the sun sensor
Symptome, die Sie bemerken können1
- The cabin does not cool down when the solar load is high
Was der Fehler beeinflussen kann1
- The control module uses a stand-in value for solar load instead of the measured one
