Got Brake, ABS and Traction Light on. INPA showed error code 81 on ABS module – Brake Pressure Sensor discontinuity.
Brake Pressure sensor itself did output voltage based on Brake pedal input, but INPA didn’t show any fluctuations.
So problem with ABS Circuit board. This time gave it to modulerepair from ebay to fix the circuit.
