LDV Electric Range

It’s likely that there’s a fuse that will control this circuit, but there’s also a chance that the same fuse might also disable other functions on the vehicle. The problem is probably being caused by the micro-switch in the door jamb that senses when the door is open and sounds that alarm you keep randomly hearing. The attempted break-in has probably either damaged or misaligned that micro-switch, which is the root problem here.

A better approach would be to fix, replace or realign the switch or the part of the door that contacts it. That will actually fix the fault, rather than put a band-aid on it.

It’s probably trying to tell you that there’s a fault with the Lane Change Assist function which keeps an electronic eye on vehicles that are too close to you for you to change lanes safely. This system can be damaged if the cameras or sensors around the car are damaged or have been bumped or coated in mud or even dunked briefly in water.

While the LCA warning message is showing, you need to be extra careful when changing lanes as the car may not be able to give you all the information it once did when the system was working properly. By scanning the car electronically, the onboard computer should be able to pinpoint what’s wrong with the system. It may just need a recalibration, but this is usually a job for the dealership.
