Rain Sensing Module fault?
Hello Meirion1, thank you for your response.
Apologies, the print on the attachment is a little small...The code is listed in the first box of the attachment...B2363
I was wondering if anyone had dealt with this DTC and if so, what steps they took?

I have fiddled with mine in the past because it seemed lazy.
In your case it looks like a wiring fault is the most likely according to the code
but IMO it will be the sensor.
However first you need to measure the supply voltage to the sensor
so carefully remove sensor but before you disconnect the wire attach a piece of string to it
because if you lose the end down the hole it will be difficult to retrieve it.
If you have a voltage then I assume that the sensor is at fault.
used ones are available.
AFIK complete failure of the sensor is very rare.

Hello Gijzzy,
No, at the risk of sounding facetious, it only rains here half a dozen times a year, so I am ignoring it?
I did, however take up Meirion1's suggestion and tested for voltage (which was there), so (as he also suggested) I think the sensor has failed?

I have seen that same code in my FEM... i don't know what would have set it, since my auto sense wipers work the same as always (which is to say, wiping way more than actually needed). I have several reasons to suspect the FEMs in our cars are poorly coded, or otherwise have internal hardware failures. Time will tell if this gets worse.
Likewise, I'm ignoring it unless there's an actual failure.
My FEM also sets a code B2496 for "anti theft horn circuit short to ground" and when cleared immediately returns. Service data says this is the passive horn (the "chirp" you get when trying to lock with a door open). Well, the FEM isn't responsible for the anti theft horns, the REM is, and mine works perfectly (all horns work fine, passive and active anti theft, as well as the service horn). Searching that code shows others have experienced the same phantom error.
