to the Rear Wheel Anti-Lock (RWAL) control module.
Circuits B113 and B114, a pair of twisted wires connect to the sensor to provide signals to the ABS control module. These circuits also connect to the
rolls test connector used during manufacture of the vehicle.
Circuit B113 connects to cavity 14 of the RWAL module and to circuit B1 of the wheel speed sensor harness. Circuit B114 connects to cavity 13 of the
RWAL module and circuit B2 of the sensor harness.
