Wheel Speed Sensor: Description and Operation
Rear Wheel Antilock Brakes
The rear wheel speed sensor is mounted on the top of the rear axle differential. The sensor converts wheel speed into an electrical signal that is
transmitted to the Rear Wheel Anti-Lock (RWAL) control module.
Circuits B113 and B114, a pair of twisted wires connect to the sensor and provide signals to the RWAL control module. These circuits also connect to
the rolls test connector used only during manufacture of the vehicle.
Circuit B113 connects to cavity 14 of the RWAL control module and to circuit B1 of the wheel speed sensor harness. Circuit B114 connects to cavity 13
of the RWAL control module and circuit B2 of the sensor harness.
