460 economy mode

I think i know the answer to this already but is it possible to disable
economy mode on a 52 plate 406?

I very often have to wait around for more than 30 minutes and to having
to turn the engine over just to be able to listen to the radio is a bit
pointless.

Thanks,

Rich

 

Hi,

Errr I'm affraid not.
Come on, it's a good feature I think, to avoid flattening the battery such a
foolish way. I have it on my '02 206 and I think it's a good thing. Why not
reading instead ?

Regards,

 

I hear what you're saying. Sadly I like reading and listening to
music/radio ;o)

Yes it's a great feature, I can't disagree with you there. It would be
nice to have an option though.

Thanks,

Rich

 

I have the earlier one and you can turn the radio on when the ignition is in
the fully off position. Does that work on yours?

 

Hi,

No option for that, IMO.My 206 which have similar electronics I think
doesn't, even not through the diagbox (anyway, you should ask it to your Pug
dealer -which may be unusual as well- and pay for the job to be done, a
price which is usually sadly high).

Hello Keith,

It works, but we're talking about the economy mode here, that means, radio,
roof light, ... works, but for a limited total time of 30 minutes (2x15
minutes or 3x10 for example), after which the display shows "Economy mode",
the radio switches off, as most accessories, the only ones remaining to work
are the headlights, hazard signals, i.e "outside signaling lights", unless
you start the engine, to avoid flattening battery.
And I'll say once again it's a brilliant featuren which IIRC appeared with
full-muxed cars.

From which I assume that my 1999 hybrid Mk1/Mk2 is not fully muxed (whatever
that means)?

 

Hi,

My memory may not be accurate... Some cars (first 206s and first 406s for
example) used a partial multiplexing, hence a far lower integration in
electronics & loom.
Full multiplexing appeared in production with the 607 and later with the
307s, then later on "renewed cars", like Mk2 406 and '02 206 at least. This
structure means the car's ECU are linked each other with data buses (at
PSA's at this time, 4 were used : 1 CAN / high speed for engine electronics
and 3 VAN (Vehicle Area Network, a digital bus developped by Valeo)) for
features entering into the "comfort features" category (radio, remote
locking, aircon...), this mux'ing allowing far easier looms (with only 4
wires going to the boot in theory), hence a better integration.
That's on the fully multiplexed cars we hear of BSI.

I hope this was clear enough, and I hope it's understandable.

Regards,

 

And not possible. It's a feature of fully muxed cars and cannot be
switched off, I'm afraid

 

Thanks GT. As Nigel will remember, my 406 2.0 HDI car is a hybrid with an
uprated MK1 body (though not yet the MK2) and mechanics which (again not
fully) are akin to the MK2. I had to buy two Haynes manuals to cover it
because one does up to 1998 and the other starts with 2000. The poor old
1999 model drops in between. So whether it is fully muxed I have no idea.
Is there an easy way to tell other than leaving the radio on for half an
hour, which in itself would be unwise as the car is still running on the
original battery and I have no idea whether it would survive it.

 

I am pretty sure yours would be a normal or a semi muxed car, Keith.
To be sure look at the radio remote switch on the column. If it is a
thin type which just goes up and down and back and forward then it is
not muxed or semi. If it is a large type which doesn't move and has
buttons on it for volume and changing stations then it is fully muxed
and does the economy mode. I hope that is clear!!

 

Thanks Nigel. It is the thin type, same as my previous 405 had, so it is
obviously not the fully muxed (that phrase sounds quite embarrassing).
Sorry I took a while to get back, just had an enjoyable week with our three
year old grandson at Butlins in Bognor.
