VSA code 84-1

[098Joe]

Does anyone know the exact meaning of "84-1 sensor logic failure" as picked up by my autel scanner? I have noticed the disable button was flickering a bit and then stopped lighting up at all
TIA

Faulty wiring within the comments but it looks like a hardware issue.

Try draining all brake fluid - fully and repenish with new stuff first to save your time.

It’s normally when your VSA modulator has lost its calibration. You’ll need a Honda HDS to carry out a neutralisation procedure. I can do this, I’ve done it from time to time
