Hello all, my baby, a 94 GTI check engine light flashes steadily from when I turn the key to on and when the car is running, it has a pattern of 1 flash then a pause followed by 4 quick flashes. The guy I've recently bought it off, said that it first appeared when the new Cd player was fitted, Ive removed the F/I fuse in the engine comparment and it extinguishes the light. Any ideas are greatly appreciated.

I know what your problems is... Someone left the Diagnostic fuse in the slot.. just remove the fuse under the dash (I'll update with a pic) and it will stop

and by the sounds of it.. you car getting code 14 from your car

*EDIT*

Top left "DIAG SW" pull that fuse out... it is used to find error codes of the car

Thats list of the error code.. looks like your getting code 14

Aim of the game is to get code 12 .. which means there are no problems

Re-read the text with the picture - fuse is in to read the codes (which means it is normally not there).

Also in the picture - see the pink fuse (actually red in real life) - it's a spare. Use it to see the codes. 1 flash followed by 2 flashes is 12 - everything normal.

All this assumes that you do indeed have a Suzuki GTi. Doesn't work for anything else. :twisted:

Is there a correct way to reset the code or is disconnecting the battery the only way?

Disconnecting is the only way unless you have the hugely expensive hardware to check the codes. From memory you can reset the ECU with them as well.

I didn`t think the tech 2 scan tool could read off this early system? or was there a predecessor to the T2?

I've not seen a GTi with the Serial Data Link, for other models a Tech 1 scan tool can clear the codes or you can use an ALDL type interface and a terminal programme to send the correct data sequence 14, 03, E9. I will be incorporating fault code reads/clearing in the next issue of my Rhinoview software as severalk people have asked for this capability, personally I just disconnect the battery.
