Serkan Posted February 2, 2017 Report Share Posted February 2, 2017 Hello, I have been trying to solve a very weird problem for the last month or so but unfortunately haven't been able to find a solution. I have installed a TTlink plugin, and 95% of the time the car is running great with no issues. However, once i a while the e-throttle suddenly goes into safe mode and I get aux9/10 supply fault. More often I get it at first start in the morning but it also suddenly happens while driving too. Also couldn't find anything weird in the logs. Voltage steady around 14v, have checked all wiring, changed battery (higher cranking amps), also strange thing is that I can't replicate the fault, happens completely randomly. Today it happened while I was looking at the runtime values / ecu status tab and noticed that all of a sudden aux 9/10 supply went to 0v while internal 12v was still reading 12v, and Hardware Block 2 went red with an error for about 10 secs and then turned green again while aux 9/10 supply was still 0.. switched the ecu off then on again, started the car, everything perfect again... would really appreciate a help with what to look out for. Thank you very much. Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 3, 2017 Report Share Posted February 3, 2017 Hi Serkan,The hardware block error is usually an internal fault such as a failing solder joint. The ECU will likely need to come back to us for repair. Please send a message to tech support via http://www.linkecu.com/contact/ for info on the return process.

Serkan Posted February 10, 2017 Author Report Share Posted February 10, 2017 Hi, just wanted to share an update on this matter, before contacting tech, I just thought I'd inspect the wiring loom, and I found that a piece of wire (from pin 117 ethrottle motor +) about the thickness of a hair was sticking out through the insulation. I'm guessing that this thin wire was touching somewhere and probably grounding the throttle motor. I fixed and isolated the wire, been driving it for the last few days, everything seems to be okay now. No fault codes at the moment but I'm thinking if I should be worried about the hardware block 2 error that I was getting when I had the problem. Could it have done any damage to the ecu?

Adamw Posted February 12, 2017 Report Share Posted February 12, 2017 Hi Serkan,The aux outs do have over current protection so it is unlikely to damage the ECU. As far as I know however, a short circuit wouldnt normally cause a hardware block error so you may potentially still have some other problem. Keep a close eye on it for a while and let us know if any errors re-appear. Quote Link to comment Share on other sites More sharing options...
