Hva betyr feilkoden?
Hall sensor 6 in the convertible roof gives no pulse when the hydraulic pump is running, and its power consumption is below normal. The cause may be the signal wire between the sensor and the control module being short-circuited to battery voltage, a damaged sensor, or an internal fault in the control module. The roof may then be operated only in a limited way or not at all.
Mulige årsaker
- The signal wire between hall sensor 6 and the roof control module is short-circuited to voltage
- Damaged hall sensor 6
- Internal fault in the convertible roof control module
Hva du kan gjøre
- 1With the ignition off, check that the connector at hall sensor 6 is firmly seated and not corroded.
- 2Check the signal wire from hall sensor 6 for damage, chafing and pinching.
- 3With the ignition off, use a multimeter to check that the signal wire has no battery voltage. Voltage means a short to positive, and the wire must be repaired.
- 4If the wire is in good condition, have a workshop replace hall sensor 6.
- 5If the fault remains after this, have a workshop check the convertible roof control module.
