Scotchlocks are always a big no no with car electrics
As for plumbing into canbus i would refer to the instructions with the reversing sensors and fire an email to the supplying company before i considered any chopping in.
If they come courtesy of flee glift via ebay personally i wouldnt fit them to a can bus vehicle.

The amount of current drawn by the sensor control unit is tiny compared to the lights, I don't think you are risking anything. I've fitted them to my last Picasso and they just worked fine.
|
I have fitted a set of sensors supplied by Dolphin Audio to my Fiat GP. They work very well,in fact they exceed my expectations for a set costing less than £50.
As Steve pointed out the current drawn is negligable and very unlikely to upset the canbus system.
I have been considering fitting some to the front,but have not yet worked out how to connect them to come on with the ignition-unless I run a wire from the cigarette lighter,something I`d rather not do. Wiring to the battery is an option but might drain it if the car is left unused for a long period.
Any suggestions?

Yes, wait until you're in slow moving traffic and see how long it is before they drive you insane. Separate dash mounted switch needed.

I would wire them to the brake lights, but having an automatic helps, next time you park, see if you are pressing the brake pedal at the points where you get close to something. You could also add a large electrolytic capicitor to keep them running for a couple of seconds after the pedal has been released. This should stop false alarms in traffic or when just stood still next to a post or kerb in a carpark or something.

Wouldn't you be better wiring it to the reverse light, then it only comes on when reverse is selected?
|
Mine only come to life when reverse gear is selected. Otherwise the little readout on the dash is dark and quiet.

The OP mentioned problems with a sloping bonnet, so I think it is reasonable to assume they were talking about front sensors.

front sensors? how close does he want to get....close enough for the car in front to have a problem getting out?....leave a gap PLEASE

"close enough for the car in front to have a problem getting out?....leave a gap PLEASE" - Who gets out of the boot?
|
|
but seriously, anyone who relies on parking sensors is just a sloppy driver, more than likely they are cut from the same cloth as the front foglight brigade
|
Probably cant be bothered to use their indicators either, and complain about those who dont use theirs.
If you need sensors to park a car should you be driving at all?

Have to admit, I do agree a little bit with that particular element of your post.
I have driven vehicles equipped with sensors but can't recall a situation where they were giving me information which was not already available by using eyes and properly adjusted mirrors.
I can see the point if fitted to a van or truck with restricted rear vision but on a normal car it just doesn't seem to me anyway to make a lot of sense.
Not for me to tell others what they should do or prefer of course. Just my humble and so on.....

Hard for me to judge where the back of the CC3 is.
Parking sensors are an aid - if I know there's only a car behind me and they are still beeping, I'm fairly sure I'm not going to hit it.
An aid, but not to be relied upon.
|
As the OP pointed out,some cars have a very pronounced slope to the bonnet making it a bit hit (boom,boom) or miss to park in tight spots.
I think fitting parking sensors is one way of protecting my no-claims bonus.
Thanks for the suggestions,I think a seperate dash-mounted switch is the way to go.

Thanks for the helpful comments. I think that a typical 4 sensor kit only draws about 3 watts, this includes the bleeper, so may not be enough to upset a CAN BUS system, when the reverse lights themselves will be 2X21 watts. Perhaps a car with CAN BUS and Led lights may be a different story.
Nobody above has reported a conflict with them fitted. A friend of mine wanted to fit a towbar to a Mondeo C, he said it had to have and adaptor kit fitted to link to the CAN BUS.
|
See tinyurl.com/dbvewc for forward facing sensor kits,they only operate at parking speed.Also radio link kits for trailers and caravans which coild be useful,none of them cheap though.
|
|
Thanks,very useful link. I note they can come complete with canbus adaptor and as you say only work at parking speeds.Morover,the have a hefty price tag at £158.
|
Ive just payed out a lot of cash to protect the can bus system on the Xtrail .
The towbar electrics are fitted via the vechical pacific kit. I was told the engine managment unit could be damaged, cost thosands to replace.
If you are coming off any of the light circuits, i would a lest connect via an interposing relay, not expensive and they do isolate from the outgoing circuit.
I would never recommend fitting a capacitor, inductors and capacitors are not a good mix with electronic modules.
