Checking electrically convertible hardtop (Continued)

Checking Hall sensor 18
Check that the hall sensor is adequately secured. Check that the hardtop has not been damaged in such a way that the part that the hall sensor is to detect does not come within the detection range.
Check that the hall sensor is working by placing a nut or screw of some magnetic material, e.g., iron, within its detection range which is 1.5 mm. Aluminium or stainless steel does not work. Check at the same time that the hall sensor's read-out value changes.
Check the connector. Check for contact resistance. Check for oxidation. Check for loose connections. If no malfunction was found, try replacing hall sensor.
