Co oznacza ten kod błędu?
The fault code says that one of the signal wires between the position sensor in the front roof section and the roof control module is short-circuited to battery voltage. The roof can then be operated only in a limited way or not at all. The fault may lie in the wiring, in the sensor, or in how the sensor is fitted.
Możliwe przyczyny
- Signal wire short-circuited to battery voltage
- Position sensor not working
- Position sensor incorrectly fitted
- Internal fault in the convertible roof control module
Co możesz zrobić
- 1With the ignition off, look for damage to the signal wire between the position sensor and the roof control module, such as chafing, damage or pinching.
- 2Use a multimeter to check that the signal wire has no battery voltage when the ignition is off. Voltage means a short to positive, and the wire must then be repaired.
- 3Check that the position sensor is correctly fitted and that its connector is firmly seated.
- 4If the wire is in good condition and the sensor is correctly fitted, have a workshop replace the position sensor.
- 5If the fault remains after this, have a workshop replace the convertible roof control module, as the fault most likely lies within it.
