Vehicle Speed Sensor (VSS)

TheVehicle Speed Sensor (VSS)is the primary sensor responsible for monitoring your vehicle's speed while cruise control is engaged. Located typically on the transmission or wheel hub, it:

• Converts rotational speed into electronic signals
• Provides real-time speed data to the cruise control module
• Helps maintain consistent vehicle speed on varying road conditions

Wheel Speed Sensor

TheWheel Speed Sensorworks in conjunction with the VSS to provide accurate speed readings. Mounted near each wheel, it:

• Monitors individual wheel rotation speeds
• Helps detect wheel slip or speed variations
• Ensures accurate cruise control operation during turns and varying road conditions

Transmission Speed Sensor

TheTransmission Speed Sensormonitors the transmission's output shaft speed. This sensor:

• Provides additional speed verification
• Helps coordinate gear shifts during cruise control operation
• Ensures smooth speed transitions when cruise control is engaged

Throttle Position Sensor

While not strictly a speed sensor, theThrottle Position Sensoris crucial for cruise control operation. It:

• Monitors throttle blade position
• Helps regulate engine power to maintain desired speed
• Communicates with the cruise control module for precise speed control

Note: The exact configuration and number of speed sensors may vary depending on your vehicle's make, model, and year.

ON/OFF Switch
The ON/OFF switch is the master control for your cruise control system. When turned ON, it activates the cruise control system, making it ready for use. When OFF, the entire system is disabled. This switch must be ON before any other cruise control functions can be used.

SET/ACCEL Switch
The SET/ACCEL switch serves two primary functions:

• SET: Engages cruise control at your current speed when pressed briefly
• ACCEL: When held down, gradually increases your set speed without using the gas pedal

This switch is essential for establishing and adjusting your desired cruising speed.

RESUME/COAST Switch
This dual-function switch allows you to:

• RESUME: Returns to your previously set speed after braking or canceling cruise control
• COAST: When held down, gradually decreases your set speed without using the brakes

It's particularly useful when you need to temporarily disengage cruise control and then return to your original speed.

CANCEL Switch
The CANCEL switch temporarily disables cruise control without turning off the system entirely. This is useful when you need to briefly take control of the vehicle's speed, such as in traffic or approaching a turn. Unlike turning the system OFF, using CANCEL maintains your set speed in memory, allowing you to resume it later.

Speed Adjustment Buttons (+/-)
These buttons allow for precise speed adjustments while cruise control is engaged:

• Plus (+): Increases set speed in small increments (typically 1 mph or 1 km/h)
• Minus (-): Decreases set speed in small increments (typically 1 mph or 1 km/h)

These buttons provide fine-tuned control without needing to reset the entire system.

Note: The exact location and combination of these switches may vary depending on your vehicle's make and model. Some vehicles integrate these functions into steering wheel controls for easier access.
