Co oznacza ten kod błędu?
The CEM monitors the signal from the sun sensor and stores the code when the signal voltage is too high. The cause may be a signal cable that has contact with supply voltage, or a damaged sun sensor. The fault usually shows up as instrument and button lighting that does not work.
Możliwe przyczyny
- The signal cable is short-circuited to supply voltage
- The sun sensor is damaged
Co możesz zrobić
- 1Check that the relevant fuses are intact. Their locations are in the owner's manual or on the fuse box cover
- 2Look for chafing on the wiring from the sun sensor, especially where it may have been pinched or rubbed
- 3Check that the sun sensor connector is secure and clean and dry
- 4If you have a diagnostic tool: follow the sun sensor value in live data and check that it changes when the light reaching the sensor changes
- 5If the fault returns with the wiring and connector in good order, have a workshop with diagnostic equipment check the sun sensor and the control module
