So I had a lot of time to run some tests and also I've used the Fiat/Lancia Tester to diagnose the ABS. I'll report my findings below.
First and foremost, errors read through the F/L Tester do not match errors from the flashing light diagnosis, as identified through the pre-facelift error code table. Codes from flashing light diagnosis ended up being something else than what is listed in the table. I believe it was a brake switch and a safety relay.
Unfortunately I did not get a real good chance to note them down, because as I reconnected the ABS a couple of times and ran the diagnostics again, the only remaining code was for the "ABS safety relay" listed as intermittent. I believe it matches code 19 from the flashing light diagnosis, but am not sure, as the code has been cleared by the tester and paperclip diagnosis shows no more error codes.
Now, most importantly, the codes are clear, tester shows no codes "no errors found", flashing light diagnosis shows no codes (only blinking 12 repetitively), BUT MY ABS LIGHT IS STILL ON. The light turns on with the ignition and does NOT extinguish afterwards, does not matter if the car is started or stopped. The car has not been moving. The light flashes correctly (I presume) with the paperclip diagnosis, but does NOT go out after ignition turned on, despite listing no errors.
Any ideas?
Second question: where the hell can I find the G272 connector, ABS fuse and the ABS safety relay? The location as listed in the connector diagram, right of the glove box, is unfortunately not where they are in my Q4 (1994 model year). Instead, space right to the glove box under the aircon vent is occupied by 3 or 4 large connectors attached to a drawer-like mechanism, allowing them to be pulled out for access. Nothing more is in there, can't see anything else. Where can I find the ABS fuse, relay and G272?
I hope to get some good ideas from you guys, thanks.
