Circuit description
The vehicle speed sensor circuit is sent to cruise control ecu assy as a
vehicle speed signal. For each rotation
of the shaft, the vehicle speed sensor sends a signal through the combination
meter assembly to the
cruise control ecu assy (see the following chart). The cruise control ecu assy
