Sensors And Catches
There are three types of sensors that are directly connected to the Convertible Roof Module (CRM); Hall sensors, position sensors and the temperature sensor. The task of the hall sensors and position sensors is to inform the Convertible Roof Module (CRM) about the position of the roof. Information about the temperature sensor can be found in HYDRAULIC PUMP . There are also a number of mechanical catches that lock the roof in certain positions.
From the signals of the sensors the Convertible Roof Module (CRM) interrupts the movement of the roof when there is a risk of passing the limit position or when the roof module risks damaging parts of the vehicle.
| Pos | Sensor type | Location | Purpose |
| 1 | Hall sensor | On the contact plate, left-hand side. | Make sure that the left side of the front roof part is connected with the frame around the windshield. |
| 2 | Position sensors | By the link system for the roof's central section, left-hand side. | To provide the correct position information to the link system for the roof's central section. |
| 3 | Hall sensor | By the link system for the cargo compartment function, left-hand side. | Ensure that the cargo compartment is completely open before the sequence continues to the position for load assistance. |
| 5 | Hall sensor | On the contact plate, right-hand side. | Make sure that the right side of the front roof part is connected with the frame around the windshield. |
| 6 | Hall sensor | By the spring bolt for the roof, left, rear. | Ensure that the rear left spring bolt is closed before everything is OK. |
| 7 | Hall sensor | On the frame around the cargo compartment, left-hand side. | Ensure that the spring bolt on the left-hand side of the cargo compartment is locked before everything is OK. |
| 9 | Hall sensor | By the link system for the cargo compartment, left-hand side. | Ensure that the cargo compartment is closed before the roof starts to move. |
| 10 | Hall sensor | On the limit position for the divider in the cargo compartment. | Ensure that the divider in the cargo compartment is closed before the roof can be opened. |
| 11 | Hall sensor | By the link system for the cover plate, left-hand side. | To determine the limit position for the cover plate when it is drawn in. |
| 12 | Hall sensor | By the link system for the cover plate, left-hand side. | To determine the limit position for the cover plate when it is extended. |
| 13 | Hall sensor | By the cargo compartment's frame contact plate, left-hand side. | Ensure that the cargo compartment is closed before the spring bolts are locked. |
| 15 | Hall sensor | By the body spring bolt, left-hand side. | Ensure that the spring bolt is closed before everything is OK. |
| 16 | Hall sensor | By the body spring bolt, left-hand side. | Ensure that the body spring bolt is open before everything is OK. |
| 17 | Position sensors | By the link system for the front roof section, left-hand side. | To provide the correct position information to the link system for the roof's central section. |
| 18 | Hall sensor | By the front spring bolt on the front roof section. | Ensure that the spring bolt for the front roof section is open before everything is OK. |
| 19 | Hall sensor | By the area for the locking system, left-hand side. | Ensure that the locking system is closed before everything is OK. |
Hall sensors
There are 14 Hall sensors installed around the roof for the roof function in the vehicle.
The task of the Hall sensors is to supply the Convertible Roof Module (CRM) with information about the position of the roof. The Hall sensors are directly connected to the Convertible Roof Module (CRM). The Hall sensor, which is a magnetic sensor, reads off if a certain part of the roof passes a sensor. This means the Convertible Roof Module (CRM) can determine the position of the roof, depending on which sensor has been passed.
Position sensors
There are two position sensors for the roof function in the vehicle. The sensors are mounted on the left-hand side in the link system. One by the link system for the roof's rear section and the other by the link system for the front roof section. The sensors read off the angle of the link system at operation. The signal is used by the Convertible Roof Module (CRM) to determine when the next phase of movement should occur.
