Donno, I just made up a open end to lighter plug made sure the
lighter socket was powered and connected a 12 V SLA to the open ends.
With a modern car one might have to be quick changing the main
battery as they have a habit of going to sleep after a while and
might switch off the lighter socket...

I guess the ODBII power line is less likely to be turned off. Or find
other unswitced/secure +V and Gnd points, obvoious place is the
around the battery terminals but there is a chnace that one
connection might get dislodged whilst faffing about with the
battery...

Yes you definitely need one. If you remove the battery your car's
computer will delete all its programming and you will never be able to
start your car again without getting it back to the main dealer for a
repair costing maybe £1000!

You are now powering your whole car through those two little pins on the
OBD connector. You will possible do more than £5 in damage if it draws
too much current.

Please name the car that does this. All that I have come across work
perfectly well after removing the battery. The major pain is resetting
the radio etc.

That depends on the wiring, but while that may be a concern, the current
draw with everything turned off would normally be measured in mA.

If you believe otherwise provide the evidence.

Only thing my old freelander needed was radio recoding

Only time I have heard of a car failing to go after a battery
disconnection is when a major sensor array has been replaced as part of
a service. Some parts are manufacturer specific unless you know the magic.

Quite. Never had a car that was worried about being powered down totally.
Except for losing relatively unimportant things like the radio station
memory.

If it does get rid and buy a properly designed one.

Woosh

No car does that's why you don't this piece of crap.

All it does is apply whatever voltage you connect the leads to into the
power pins of the OBD socket to supply the ECU, and the rest of the car.
Its effectivly just two pieces of wire!

If when removing the car's battery you accidentally short the +ve
battery lead to the chassis you will short circuit the supply you have
just connected to the OBD socket. I wonder what current will then
flow?down the car's internal wiring?

Go and find a Youtube video to show that these things work
One shows that after connecting one of these devices, then disconnecting

What would that be, Jim? It may revert to ignition timing for low octane
fuel, until the knock sensors tell it otherwise. An auto gearbox might
learn how you normally drive to some extent. But all that sort of thing
would update very quickly.

Yes but if one of the temporary wires connecting that falls off with

I think the reason I did it was partly proof of concept but mainly
because didn't know the radio code. The Disco II would take about 100
miles to "re-learn" the engine and my driving style. Freelander II is
much quicker, barely noticeable unless you want a quick take off
within the first few miles when it won't have quite the normal amount
of GO!

Thats bull****. I have replaced my battery twice now and the
only very minor quirk was that the radio needs an unlock code.

You are now powering your whole car through those two little pins on the

But the whole car is **** all when you are only powering
what get powered when the car has been turned off.
