Hello friends. I got error 88 right rear wheel sensor. i changed the sensor, but the lights are still solid asc / abs. I have heard that it may be a matter of the hydraulic control unit. I have removed the hydraulics, but it is different from the year 99 onwards (the welds tend to go away). Does anyone know if it could be a problem with the hydraulic unit? Attached photos of the switchboard and the type of hydraulic.
