Vehicle Speed Sensor Signal: Description and Operation

The vehicle speed signal is generated by the rear anti-lock brake sensor and sent to the 4-Wheel Anti-lock Brake System (4WABS) module. The
4WABS module sends the vehicle speed signal via circuit 679 (GY/BK) to all systems which require a vehicle speed signal input.
