Situation
ABS warning light illuminated.
Cause
Disconnecting front left decompression solenoid valve in the ABS hydro unit.
Maintenance
Diagnosis noticed cord24 that was fault of the front left decompression valve.
Then I looked into it by service manual.
Firstly I pulled off valve relay and checked electric continuity.
One of the cable was infinite.
I judged that this was the cause.
Thean I changed a new ABS hydro unit.
After that it worked properly.
