Observe the live stream value for the . If the sensor returns a static 0% value while the code remains active, the sensor internals are dead. Step 2: Check Physical Fitting
The humidity sensor module itself has failed internally. The standard JLR part number for this component
Strangely, a known conflict exists. Low-quality dashcams hardwired into the fuse box can create electrical noise (RFI) on the infotainment bus. Unplugging a suspect dashcam has resolved B13C2-49 on dozens of Land Rover Discovery 5s. Test by removing all aftermarket accessories before replacing hardware.
