Voltage Signal: Description and Operation
Cruise Control Status Signal

DESCRIPTION

The cruise control switches are part of the multifunction turn signal lever. These switches enable the driver to control the cruise ON/OFF, the
set/coast, and the resume/accel signals. These signals are inputs to the fuel control portion of the PCM and allow the PCM to maintain a desired
vehicle speed under normal driving conditions.
