What does this fault code mean?
Hall sensor 11 in the convertible roof gives no pulse when the hydraulic pump is running, and its power consumption is above normal. The fault may be a signal wire short-circuited to ground, a broken connection, or an internal fault in the sensor or the control module. The roof may then be operated only in a limited way or not at all.
Possible causes
- Signal wire short-circuited to ground
- Broken connection between hall sensor 11 and the roof control module
- Internal fault in hall sensor 11
- Internal fault in the convertible roof control module
What you can do
- 1With the ignition off, check the connectors at hall sensor 11 and at the control module for corrosion, looseness and loose contacts.
- 2Use a multimeter to check that the wire from hall sensor 11 has continuity to the control module and is not grounded.
- 3Repair or replace the wire if it is broken or grounded. If the wire is intact, have a workshop replace hall sensor 11.
- 4If the fault remains after this, have a workshop check the convertible roof control module.
