Thread: On-Line diagnostics - what a good idea

Don't know much about obd-2 one. Bit hard to decipher in 5 mins of looking.

I do agree that it would be "nice to have", but.....

<div class='quotetop'>QUOTE</div><div class='quotemain'>I think to buy the necessary bits and pieces for my RR would cost about $1500 - $2000. Hard to justify for personal use, when I can hook up to a test book for $30 (my local LR dealer charges $30 for a hook up and diagnosis reading / fault clearing ) [/b][/quote]

Exactly my point in Problem 3.

As for the LCD in the car solution, that's again a "nice" feature (and expensive according to the Rovacom Lite solution). According to Rovacom, the software talks via an RS232 port (the old 9-pin socket). This protocol, by it's nature requires short runs of cable (I'm not sure of the maximum, but it's nowhere near 100m). If a computer is connected directly (ie not through the internet), it works. Through the www requires more robust comms protocols (RS232 doesn't cut it). And again, it's model specific... buggered if you don't have the right equipment.

However, as you suggested a dial-up (of types) solution would probably be the easiest to set-up (I use the word "easiest" in comparison terms) IF you could get a totally integrated system that accomodates all LR ECU's. It's work that over the www, you control the remote PC with the Rovacom software on it, and get it to dial your home where your car is connected to the telephone line. Would be technically feasible, however, who out there is willing to dedicate a telephone line and PC 24/7 for other people to exploit and use the Rovacom software (not to mention Telstra's lovely line rental of $28/month)?

would be very hard to develop a system like this for a Land Rover, what Land Rover model do you base it on ? What year ? because they have different ECU's for every model and sometimes change them around every couple of years!! What functions do you support ? If you want a good system, go for the Rovacom one, not cheap but will work with all of Land Rovers systems, where as the other one I mentioned earlier http://www.obd-2.com/ only shows engine management varialbles...

Another idea would be to put in a motec or wolf 3d system, then you can plug it into your laptop a bit easier !!!

Usually though if your car dies in the middle of the simpson, it's going to need some new part, not just the computer reseting !!!

Good idea though, might be cheaper though to go and buy some manuals and do a LR mechanics course [img]style_emoticons/<#EMO_DIR#>/smile.gif[/img]
