- Anything that can go wrong, will go wrong. Plan for it as best you can.
If you get this alert and fuse F12 in the Battery Junction Block is blown, check the wire harness connected to the clutch fan clutch. The hose that prevents the electronic portion of the clutch from spinning may have broken, allowing the harness to rub against the nut that attaches the clutch fan to the water pump.
See the hose in question in the picture below. The bracket on it bolts to the front of the head.
The on in my 2019 was made of cheap deteriorated and broke. You can see a remnant of it on the left side, still on the mounting bracket of the picture below.
I repaired the chaffed wire with a crimp and seal. Re-wrapped the harness in wire loom and electrical tape. And installed a cord reinforced, oil and fuel resistant hose on the electronic device on the clutch and the mounting bracket on the head. Silicone spray helps get the hose on to the nipples of the device and the bracket. I found it easier to install the hose on the bracket first while it was clamped in a bench vise since the bracket is made of soft aluminum, then install it on the electronic device.
