Diagnostic Check. lights constantly flashing (no code)

Just fitted my Fmic and other bits and bobs. Finally got the car back together and my red warning triangle is lit constantly now when i start her.

Done a diagnostics check tonight and the o/d off light just flash's and doesent give a code out. I noticed as well, the spoiler light was flashing at the same rate. I have removed the front spoiler to get the fmic to fit.

 

Is this the reason the red warning triangle is on?

It's not the OD OFF light that flashes the error codes it's the yellow engine warning light.

 

But yeah if you've removed the active spoiler but left its ECU connected I believe you will get the MIL light on permanently.

both the od off light and the engine light was flashing together with the spoiler light.

 

Where is the spoiler ECU? Is it just to simply disconnect it?

the light that gives you the code is in the top right display shaped like an engine, just in case were confused here .did you connect the right pins on the plug ???

Just took the spoiler 30 Amp fuse out in the drivers footwell. Took the ecu fuse's out and put the back in and started the car and still getting the warning triangle light staying on. Even disconnected the battery but no joy.

 

Do i have to disconnect the active spoiler ecu? And if so where abouts is it?
