Hi all

 

ECU- SupraLink (G4+ EXTREME)

 

I disconnected my battery and unplugged the ecu to do continuity tests on my trigger wires as i was having a trigger issue, how ever now i have no Check engine light, no Battery light and no oil light when i switch to 3rd ignition my laptop now has no communication to the ecu

 

Ive pulled every fuse on the car none are blown any ideas? its a Mk4 Manual NA-T

 

ive posted this to Link aswell to see if its just an ecu issue but im hoping someone has had this issue ):

I would start with undoing what ever you did while you was testing , if it was just testing and no changes made revisit the points you tested and check good connections and that all pins are still in plugs correctly. Also check to see if you have power at the ecu. If not then check the wiring diagrams on the home page in the repair manuals

Thats oil level not temp. Sounds like a power issue somewhere

 

Why do we have two oil lights? one red on the left panel and this orange one on the right panel?

 

Also Issue is no resolved problem was the orange connector plug i now have power and i am able to access the ecu again.

One is oil pressure, the other is oil level
