Towbar fuse location.

[Tom,]

Does anyone know where the RX450h+ towbar fuses are located? I have lost the Ignition-On 12V on Pin 10 of the towbar connector due to carelessly shorting it while fault finding on the caravan fridge. All fuses in the two fuse/relay boxes under the bonnet have checked OK.

Although checked this video suggests it’s in the engine bay fuse box at 3.30 minutes.

Thanks Steve.

Unfortunately neither of my two fuse/relay boxes resembles the one in the U-Haul LHD 2010-2022 RX450H. Mine is a RHD 2023 RX450H+. I had wondered if there is a fuse in the wiring loom for the tow bar electrics.

I have discovered a third fuse box on the right hand side of the boot, next to the 12 volt Battery. Unfortunately all those fuses are OK as well so am no further forward.

The only other thing I can suggest is follow the tow bar wiring loom back from the external socket to where it enters the car then remove the trim on that side and take a look for a fuse.

The car is due its first service next month so I will probably get the 'experts' to sort it out. It will cost me though!

I did the same thing on my gen 4. I'm prety sure that on mine they were located behind the right hand side boot trim panel. I balked at trying to get access to them so it went to the local dealer. If memory serves it cost around £90 labour th replace the fuse.

There is a 4th fuse box located behind and under the glove compartment. You have to be Houdini to get to it so I did not attempt to remove and check these fuses!
