Resolved Help! with 1g ABS wiring

[Hopperman]

I bought this 1992 Eclipse, and it has ABS. The ABS light comes on instantly when you turn the key without pressing brakes or driving. I am pretty sure the reason is electrical, I think it fails the self diagnose so the light comes on instantly.

So if you could help me understand how the wiring works in these ancient ABS modules that uses two relays (pump relay and valve or solenoid relay).

Thanks in advance

I've got a similar issue. On mine there's 2 yellow wires that run outside the loom on the abs plug at the abs valve body and go into the relay box. They got cut and I think hooked up backwards. Have you done a visual inspection of the wires and or speed sensors? I know that the sensors themselves can get dirty or not pick up the signal because there's s*** on them.

My wires were good and I dont remember anymore how they should be wired. But my issue was the abs ecu, so if you have same problem i recomend to change it for used one (they are cheap), that fixed my issue, but could be wires also. And my diagnostic skill says that it cant be sensors if you have not driven It at all, so if the light comes on instantly it fails the self inspection so problem should be electrical in my opinion, hope this helps little bit.

Actually my abs light flashes as key is turned. Then goes out when started and turns back on while driving. I tried getting a code using an led test light, but it didn't give any.
