DS3 CanBus electics or not?

[John S]

There has been some discussion amongst some members about the need to get CanBus compatible LED's etc when upgrading lighting.
As I understand the CanBus system its' supposed to monitor bulbs against failure and warn the driver of a failure.

From what I've seen tho experiment is that it either doesn't work or just doesn't exist.

Can anyone confirm or deny the existence of CanBus monitoring on the DS3?

I Can Confirm It John,

When I Had The Lexia Tool Plugged Into Mine It Warned That My Boot Light Only Had A Couple More Days Left To Live...

The Lexia Was Right... :L

Very strange, mine wasn't bothered by having sidelight, dip beam or main beam disconnected, neither was it worried when interior lights were removed.

I do not think it actually displays an Error, but just lowers/stops the current to the faulty bulb but i could be wrong.

Canbus is IMO a monitoring tool, BMW/Mercs/Audi do display the faulty bulbs on the Dash but whether the DS3 does that i have no idea.

I tried using normal LED bulbs with no resistors and they flash due to not enough power being sucked up, when i bought the canbus LEDs it works faultlessly.

I was messing with the reversing light wires to get a feed to my aftermarket parking sensor and stuck my multimeter probe into the socket where I'd removed the bulb from, with the reversing light on of course! I couldn't get a steady reading at all so something was going on ( in fact it sounds like the fluctuating voltage/flashing that SiM22 refers to).

Also the CAN Bus twisted wires referred to in this link http://www.bridgwater-electronics.co...CAN+Bus%3F.php can be seen when you rummage around behind the trim behind the rear light clusters

Like I Said John Mine Flashed Up On The Laptop When The Lexia Was Plugged In...

That's OK ........... IF you have access to a Lexia

eBay ? :L

It is very expensive kit, and if you really trust someone you do not know to provide you an Oficial Citroen software which is 100% working well good on you, but somehow i do not

You are better off finding a bent official citroen mechanic with access to Lexia
