I've been messing with my consult on and off for ages now but have never got it to work.

I have a S2 RS-4 S and am trying to use one of those cheap Chinese consult adapters.

I am pretty sure my ECU is stock, my consult port has a yellow Tx and a brown/yellow Rx wire, no clock wire and a black ground. I havent seen those particular colours on any of the pinout diagrams but I assume doesn't matter, and I have read Pete's posts before that no clock on the RS-4 S is normal same as the R34 Gtt.

I have so far tried ECUtalk windows XP and 7 laptops, a Windows CE mobile device. As well as writing my own python program in Linux that works similar to Hyper Terminal. I have used 2 different Serial - USB converters one of which is FTDI based. No luck on anything so far.

When I use the terminal program it works fine transmitting to itself and other systems so the Serial comms side is fine, when I turn the key on the Stagea to ON I receive a 0x0 hex character, but no initiation string I have used so far has yielded any results. While sending random hex chars to the consult port (while the Stagea isn't running) sometimes returns different hex characters so I am assuming the consult adapter I am using is working.

I was hoping Pete or one of the other more experienced members could give me an idea on what the problem could be, I'm running out of ideas.

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
