RABS Speed Sensor Mini-Schematic:

DESCRIPTION
Code 9 is generated by the module's detection of high speed sensor resistance. The anti-lock electronic control unit will consider the speed sensor circuit to have a high resistance when it exceeds approximately 3 K ohms. The code may also be generated by a failed internal module circuit.
