<div dir="ltr">Hi all,<br><div>Anybody got any experience with HUDs?</div><div><br></div><div>I bought this simple HUD from FastTech:</div><div><a href="https://www.fasttech.com/products/9686283">https://www.fasttech.com/products/9686283</a></div><div>When connected direct to the OBDII port, it powers on and seems to function. When I connect it to the OVMS module with the standard <a href="https://www.fasttech.com/products/9652027">https://www.fasttech.com/products/9652027</a> the HUD doesn't even power on.</div><div><br></div><div>It's stated draw is 200ma which afaict should be fine. I'm pretty sure the 12V power is getting to PIN 16... though I will try again to make sure. I only have a crappy little Multimeter.</div><div><br></div><div>On the Troubleshooting it states:</div><div> "HUD only available for cars with OBD2 and EU-OBD agreements ... HUD Products don't support JOBD and OBDI protocol."</div><div><br></div><div>The OBD HUD connector has the following pins:</div><div>
<p style="line-height:100%;margin-bottom:0cm;background:transparent">4* Chassis</p>
<p style="line-height:100%;margin-bottom:0cm;background:transparent">5* Signal Ground</p>
<p style="line-height:100%;margin-bottom:0cm;background:transparent">6 CAN High</p>
<p style="line-height:100%;margin-bottom:0cm;background:transparent">7 <b>ISO9141 K Line</b></p>
<p style="line-height:100%;margin-bottom:0cm;background:transparent">14 CAN Low</p>
<p style="line-height:100%;margin-bottom:0cm;background:transparent">15 <b>ISO9141 L Line</b></p>
<p style="line-height:100%;margin-bottom:0cm;background:transparent">16 Vehicle Battery
+ve</p>
<p style="line-height:100%;margin-bottom:0cm;background:transparent">* Long pins</p>
<p style="line-height:100%;margin-bottom:0cm;background:transparent"><br>
</p>
<p style="line-height:100%;margin-bottom:0cm;background:transparent">These are the standard OVMS supplied pins:</p>
<p style="line-height:100%;margin-bottom:0cm;background:transparent">4 Chassis Ground</p>
<p style="line-height:100%;margin-bottom:0cm;background:transparent">5 Chassis Ground</p>
<p style="line-height:100%;margin-bottom:0cm;background:transparent">6 CAN H (Primary)</p>
<p style="line-height:100%;margin-bottom:0cm;background:transparent">14 CAN L (Primary)</p>
<p style="line-height:100%;margin-bottom:0cm;background:transparent">16 +12V</p>
<p style="line-height:100%;margin-bottom:0cm;background:transparent">So obviously the main difference is the lack of K / L lines in the OVMS ... but I wouldn't have thought that would have prevented it from powering up.</p><p style="line-height:100%;margin-bottom:0cm;background:transparent">Does anybody have any thoughts on this?</p><p style="line-height:100%;margin-bottom:0cm;background:transparent">//.ichael</p><p style="line-height:100%;margin-bottom:0cm;background:transparent"><br></p></div></div>
