mind boggling experience..
My RAV4 throws the ABS lamp at 60 KMh. and remains on till ignition off. speeds below 60 no problem.. All 4 WSS are cleaned tooth wheels cleaned. Cannot figure out what next. The ABS actuator is 44510-42020 and ABS ECU is 89540-42110.
The pin outs of neither of two are not available after rigorous search.
there are two VSS on the transmission. Are they involved in anyway??
Diagnostics give several C errors . Non of them are speed related.
(C0278,0274,1244,1246,1203)
Any help would be greatly appreciated…
Cutting the ABS lamp wire is acceptable, if I knew which one..

Cheers..

Instead of cutting the abs wire, simply remove the ABS relay from the fuse\/relay block. The light will remain on but the function will no longer work. <\/p>\n\n\n\n

Looking at the wiring diagram(provided) there are four wheel speed sensors and one Deceleration sensor involved. Maybe that or an issue in the wiring harness is causing the issue. <\/p>\n\n\n\n
