fangio 1 Posted March 11, 2015 Can anyone with PP2000 help with this problem please. Have activated PP2000 and connected to ECU but it returns with: 'ECU has not replied.' I have the leads supplied by Rich at Lynx, which also have battery leads attached to the Diagnostic tool - I assumed that they should be attached to the vehicle battery. This a SC 205GTi 6 done by Rich running the std ECU set-up. Thanks Guys. Share this post Link to post Share on other sites
Paul_13 212 1 Cars Posted March 11, 2015 Have you connected it by the 2 pin plug? Is the ignition on and the engine off? Share this post Link to post Share on other sites
fangio 1 Posted March 11, 2015 Yes to all. also just tried Diagbox and again the same non-response from ECU. Share this post Link to post Share on other sites
Paul_13 212 1 Cars Posted March 11, 2015 I wonder if the diagnostic plug is wired up correctly Share this post Link to post Share on other sites
Paul_13 212 1 Cars Posted March 11, 2015 I've personally never connected to the ecu like you are so can't really offer any experience Share this post Link to post Share on other sites
Slo 283 1 Cars Posted March 11, 2015 Is this the 2 pin plug obd? I asume you've tried it both ways round? Share this post Link to post Share on other sites
fangio 1 Posted March 11, 2015 [/url][img=http://forum.205gtidrivers.com/This is the plug. I didn't think it could go another way due to the clip? Share this post Link to post Share on other sites
Paul_13 212 1 Cars Posted March 11, 2015 That's a lot different to the plug I have. I take its a custom loom? Not your standard gti6 conversion loom using oe plugs Share this post Link to post Share on other sites
fangio 1 Posted March 11, 2015 It still has only two wires from the ECU though. Knowing Rich I'm sure it's all connected up correctly. Share this post Link to post Share on other sites
James_K 6 1 Cars Posted March 11, 2015 You don't need anything connected to the battery to get it to work. Not sure if that will help the problem you have though Share this post Link to post Share on other sites
Slo 283 1 Cars Posted March 11, 2015 (edited) Yikes wth is that......Do those wires definitely go to the ecu? Edited March 11, 2015 by Slo Share this post Link to post Share on other sites
fangio 1 Posted March 12, 2015 Yes. They do. This was set up by Rich @ Lynx and he definitely knows what he's doing. I don't know what else to do now, except to try it on my son in laws GTi6'd 205, as the programme seems to be working. Share this post Link to post Share on other sites
Slo 283 1 Cars Posted March 12, 2015 If the program is running then the usb lexia thing whatever you call it is working as it wont run without it being plugged in and correct driver installed. Share this post Link to post Share on other sites
fangio 1 Posted March 12, 2015 Well, just came back from trying my son in law's and same result. Share this post Link to post Share on other sites

Alan_M 66 1 Cars Posted March 15, 2015 As Slo said, the program won't run without the gizmo plugged in. It'll get to a point where PP2000 will ask you to plug the gizmo into the USB, if not it'll shutdown. I'd imagine if the drivers weren't installed, it won't work either. A green LED should alight when working correctly (plugged into the USB of laptop and drivers installed). To connect to the my HDi, start PP2000, plug gizmo into USB, plug into the OBD socket under the steering wheel when told to and follow instructions. I have never used the croc clips, although I am intrigued to know what they're for. I'm wondering if they can be used on older management systems too (it has twin male connector for earlier diagnostic plugs). Share this post Link to post Share on other sites
Slo 283 1 Cars Posted March 15, 2015 Old style 1 socket 2 pin plug odb the crocs are battery terminals for the vehicle you are plugging into I have yet to use it on my turbo engine to find the cause of my misfire Share this post Link to post Share on other sites
