I purchased an OBDLink SX this week to make use of the new features the STN111x firmware brings over the std ELM series.
The problem is the SX will not, and I repeat WILL NOT connect to the vehicle at all.
I've used OBD scanners for years and am quite adept at making them work, even rewiring connectors to access the various pin-out's on the DLC's on various makes of cars.
The SX connects to multiple PC's without issue.. the Orange LED illuminates indicating the presence of drivers (even though I too got the wrong instructions telling me to look for a Blue LED), I soon saw past that error.
Device manager shows everything as being correct.
Terminal programs and various other software's all talk to the SX and identify it as being on Comm 4.
The problem is when it's plugged into a vehicle, nothing!
It's as though the car may as well not be there at all.
However doing a direct side-by-side comparison with an old ELM scanner, this connects right away without a problem at all.
The DLC provides J1850 PWM across pins 2 and 10 and also has a CAN Link across pins 6 and 14.
In this case the OBD is issued over the J1850 protocol.
I have tried the SX now with all the provided Scantool software and 3rd party offerings from Palmer and various others OBD2 spy, Freescan, OBD master etc.. non of which can get it to talk to the host vehicle.
The older ELM scan works flawlessly.
Which scan tool are you using? OBDLink SX
Connection type (serial port, USB, Bluetooth)? USB - Comm 4 - verified connected
What is the operating system? Specify whether it is 32 or 64 bit 32-but but tested with both
What is the year, make, model, and country where the vehicle was purchased in, new? 2003 Aston Martin V12 GT, UK
If known, what is the engine type (gasoline or diesel, number of cylinders, displacement). Petrol, 12, 6000cc
Which software are you using (name + version)? Essentially tried lot's and everything on the supplied CD.
Describe the problem in detail: ECU not found
Exact text of any error messages you received.
UNABLE TO CONNECT
when I set the protocol to J1850 PWM
SAE J1850 PWM
Misc codes sent / received from SX
UNABLE TO CONNECT
and finally just to be clear, the older ELM327 v 1.0 I have connect 100% every time without fail and produces feedback from both ECU's
