Hi all,
I have recently purchased a generic fault code reader off eBay (a model D900) as a stopgap measure until I can afford a Blackbox MSV-2 device. Unfortunately the device I have purchased, although supposedly being for 'any' car fails to connect to my Discovery 3 (my car was first registered 04/2005). I have tried connecting in various different sequences but on every occasion I get a message that the device was unable to establish communication with the vehicle.
The device is supposed to be OBD11 & EOBD compatible and should use any of the following protocols : CAN, KWP 2000, ISO 9141-2, PWM and VPW.
Can anybody advise my if this device should work or if there is anything special I have to do to allow it to communicate with the vehicle (other than just plug into the OBD port, and turn the ignition on?).
Many Thanks
Keith

You are beat - only the guy in Cyprus, (Faultmate), has truly beat the forces of economic control and gained unlimited access to the electronic internals of the D3/LR3.
I have a ScanGauge II that I use to give me a number of readouts, voltage, water temperature, manifold pressure, that sort of thing and it will maybe even reset a MIL light if you are very lucky and perhaps read the odd emission system code.
I have the ScanGauge set to CANLF, something fairly obscure as befits Land Rover and other exotics such as Volvo; most others, (GM, Ford, and Chrysler), use the slow rate, CANSF, but not Land Rover. For some time, I thought the setting was CANSF, and while I got the ScanGauge to work, I later decided I was probably wrong and it is CANLF instead.
If however, your unit accepts CANLF, you will still not gain much, and you could try it on CANSF. All the US Government requires is that the manufacturer make it possible for the unwashed to access codes related to emission controls; all else can legally be encrypted as the manufacturer wishes. The quid pro is that there is no apparent law against hacking the code, hence the degree of security can be significant. Control is Power, and Power is Money.
CANLF stands for Long ID and Fast interval or Long Format or 29 bit and 500kbps
CANSF stands for Short ID and Fast interval or Short Format.
CAN stands for Controller Area Network
In my fooling around trying to determine the setting, once I caused all the trouble lights on the dash to illuminate and the 3 to drop to the stops. Fortunately disconnecting my ScanGauge from the OBD socket and a restart after a few minutes and all was well. In other words, there is just the hint of perhaps the high cost of education. 2005 LR3 HSE 4.4L AJ-V8 petrol; Traxide Dual Battery; PIAA 2500K Yellow Ion H11 Fog Light bulbs; CounterAct LT-2 Capacitive Corrosion control; LLumar AIR80 Blue clear Infra Red blocking side window film; Liftgate manual release; Schrader Valve "air in" mod to OEM air suspension reservoir tank; Akebono ceramic pads; OEM solid vented discs; LR4 design hitch receiver; Wiggs D4 MOST bluetooth module; Clock on the Dash; 3 Flash signal light mod; Backup Camera; 2015/16 Nav Data update.

Hi Guys, There is also a guy in Canada that seems to know a fair bit about the inards of D3 Electronics. I have just bought the 11DToolBeta from Gap Diagnostics. I set all the heights at each wheel, then set the "Tight Tol" mode prior to wheel alignment. Checked all the stored faults - 7x and then reset to zero. If I can use it then anybody can, it is really straight forward with great 'by return' help from the guys in Canada........ AND there are no cables!!! BUT you do have to have working cruise control buttons as they are used for operation of the module. Life always good with a Landy
