Wipers and headlights ON and not turning OFF, Indicators not working.

Hi All,

just turned on the ignition to find the wipers and head lights are on despite being turned off. Unable to turn them off no matter what i try. Indicators and windscreen wiper fluid are not working either. A string of other warnings (ESC not working, TSA not working, Reduced braking performance, Uphill assist not working, Down hill assist not available) are also lightning up.

Does anyone know what the hell is going on and how this can be fixed for the time being, as its the weekend and the dealer isn't open?

Before you do much else, make sure the battery is fully charged, either by charging it or using a proper meter. (Don't rely on the Grenadier dash readout).

If you are lucky, low voltage is upsetting the electronics. Then try the battery connections and the earth connections around the truck. If they are loose, you can get some weird effects. If you are unlucky, it will need a module change.

Sounds like a module behind steering wheel

If you try those few suggestions with no luck, I’d unplug the main battery for a few minutes. Remove the ground cable, wait a few minutes and plug it back in.

I have had this fault they replace the indicator/wiper stalks if you’re in a bind you can remove the wiper fuse to drive it back home.

Yes it is indeed most probably a hardware failure, and the module should be replaced: I had that problem before delivery of my car.

Thanks for the replies.

Had ineos roadside assist look at it and they tried disconnecting the battery for 10min without success. Flatbed booked to tow it back to the dealership. I'll try fully charging the battery if i can get my hand on a charger
