Explain Nanocom readings.
Is this normal?

Why is bonnet low?
Factory mode, is what?
Should my Td5 be “Learnt”?

Why MIL fault?

First of all. If you dont know what your doing. Do not play, youll ruin your car, dont mean to come across as rude but ive seen it many times. Becomes very difficult to then fix.

High / Low means active/not active.

Open and close your doors and youll see the values change, same for the bonnet. The refer to your door switches.

Mil status is to turn the engine management light on and off. Regardless of a fault appearing. Obs not ideal to turn it off.

Thanks.

I’m not playing but just trying to understand. And to me, they don’t make it simple. It would be good to get an idea of what is ok/normal so if something alters or has a problem I know what it should/was before.

So you think
my bonnet switch isn’t working
My MIL is working
My passenger door switch isn’t working

Ok good Smile

To test your switches, have the nano open on that page and push the switches in and out. If it doesnt change switch is broken. If it does. It works.

Tbf apart from really indepth fault finding then the live data and fault code pages are your best bet!

Its not straight forward, could be easier i suspect its down to programming limitations
