Mk1 Galaxy 2.3 Dohc Engine With Minimalistic Electronics

Led lights up for a while when turning the key to running position. In case I remove key from PATS tranceiver and turn on the power, led blinks rapidly. I'm sure I have the led wired correctly now.

 

By the way, does anybody know what is the purple wire? Goes to ECU pin 58, central junction box connector P6 and also to instrument cluster. Also looks to be going to cruise control box, power mirrors, then it changes color to red when it goes to radio connector pin 1. There is one white wire as well connected to this purple, but that I don't know for sure where it goes.

 

But this likely has something to do with the diagnostics... And would be nice to understand what it is.

Sounds like your unlocking the immobiliser then rather than bypassing it, so that rules that out. But is probably good overall.

 

Don't know what to suggest further at the present time, It might be worth working on the TIS setup though.

Oh yes, problem solved. :)

 

Turns out that my ELM327 just did not like talk to ECU of my Galaxy engine anymore, even it did like to talk to it earlier. Also it still likes to talk with my Fiesta EEC-V box, so seems that it is a bit picky...

 

So my problem is now solved after I purchased OBDlink SX cable from Ebay and that works nicely. A bit stupid issue, but also a bit weird at the same time though... But I'm happy that I can now continue with my project(s) and not spend any more time to troubleshoot the OBD connection issue.

Well thats rather odd, though maybe its just starting to fail. That said a lot of the diagnostics kit available is rather poor quality particularly if its been sourced from eBay or similar (misprintings on the product, one of the ones i brought had 4 different spelling mistakes on a total of 10 words!) and it can be hit and miss as to what they support protocol wise so its not that surprising really.

 

You solved your own problem at least though so all good there. Hopefully you will get to use the engine as you intend to at a later point.

Likely I will now put this engine + test trolley to storage for a while and continue working with it later. But at least now I can say for sure that the central junction box is not needed for the engine to run perfectly well. Only boxes that are needed with manual gearbox car are EEC-V and PATS (+transceiver for the key).

 

I still have also the instrument cluster connected, since I need to figure out how vehicle speed sensor and speed pulse leaving from the instrumentation cluster actually works... From the wiring diagram it looks that VSS gives its signal to the instrument cluster and that sends it to ECU with Galaxy, even with most of the other EEC-V equipped cars VSS wires go directly to ECU. Would be nice to know the difference of speed pulse and VSS signals, but at least they have separate wiring.

 

Related to the OBDlink SX cable I purchased, I'm fairly sure it is genuine, not any cheap copy even purchased from eBay. It included also OBDwiz application license key and instructions that were looking perfectly legitimate and worked for the application I downloaded from official obdlink.com website. When purchasing from eBay there are usually multiple options where to purchase, so eBay itself does not mean that the product is pirated or bad quality. Likely I will purchase some OBDlink wireless device later on, but now I'm satisfied with the cable version for the time being.

No very true - there is some absolute junk on there to be wary of though (usually evident by checking the addresses against the item location, when they appear to be trying to hide details of it coming from abroad etc).

 

Some bargains can be had from there (2 of my current vehicles came from there) but not everything is good!

 

If you get the chance to try the same cable on another Galaxy that might give you an answer if its something wierd with the cable gone wrong, or somehow related to the wiring. But your working now which is the main thing.

At least you found the answer,it could have been a tricky one.

 

When all the obvious has been tried, it sometimes pays to go through the basics again.
