If I try with my scan tool to write VIN, I get a message that VIN writing is not allowed. So now what?
Was the hydraulic unit a new or used item? If used, the VIN's don't match and I don't believe you can change that. It's a one time write in the ABS.

Ahhhhhhhh
You are correct! But I found a way around that just a few moments ago. The electrical part of the ABS module comes off. So, I switched that from the one to the other and now the light is off and the brakes are fine.

Good to know! Used unit is ok for hydraulic issue as long as you swap the electrics. Have faulty electrics and a new one is in order. Thanks for sharing.
