Abs, speed input, abs light.

[m0sad]

Hello all, 

Lexus sc300

G4x xtreme 

I have tapped my abs sig, and all is good from that side, i see the speed and signal is great, understood that it's reading from 15kph because the minimum voltage is 1.5v.

 

One question please, 

1. I see an abs light on my oem dash, how can i trick the abs computer that there isn't an issue please?

Most likely the ABS uses a differential input rather than referencing ground.  Have you only connected one wire?
