Clicking non stop from engine bay

[Sun God]

There is a clicking noise coming from near/around my PCM in the engine bay that cycles every 30 seconds or so non-stop when the engine is off. It started after installing a series of upgrades. The car drives fine, but I have to disconnect the battery at night in order to prevent it from draining. Has anyone else had this experience, and if so, how did they solve it?

Seems obvious. Your upgrades aren't really an upgrade are they? Work the problem backwards until you resolve it. That means uninstalling whatever you did.

Check and make sure the key is far enough away

My wife’s sport will do this anytime someone walks near on Proximity Unlock if her keys are on the Kitchen counter

Termites.

Key is far away. This seems to be some test that can’t complete and keeps turning over. I figure someone here has experienced this and solved it.

Looks like this is coming from the ebb module. (Not anything I upgraded) Anyone here have issues with the ebb not going to sleep?

What were your upgrades?

I've noticed this same clicking, but just assumed it was a quirk of these newer high tech vehicles. Has anyone solved this problem, or at least figured out what causes it?

The clicking from the EBB is completely normal. It will do it for a little while after shut down and some other times intermittently, but it shouldn't continue non-stop.
It does it as part of it's normal shutdown/startup procedure

so the issue does seem to be with the electric brake booster being stuck in a panic mode loop cycle. This apparently can happen if the vehicle is flat towed. Mine was actually towed at one point recently. I’m going to try a reset procedure this afternoon. If that doesn’t work, Ford has a special service message on the topic SSM 51415.

Well, that explains why my 23 Explorer (wEBB) is always clickity clacking and my 21 Bronco 2.3 (VACB) does not. Mystery solved. @Ducati1098 is like the Neil DeGrasse Tyson of the Ford universe.

Your description is exactly what I've noticed, so probably nothing to worry about then. Thanks!
