Lexus CS-350 2011-2014 Aftermarket Cruise Control Kit

Description

Cruise control is an essential product that improves driver comfort and vehicle safety for passengers. This system not only maintains a steady speed at the touch of a button but also acts as a driver-set speed limiter where drivers can choose a maximum speed according to road conditions, allowing the vehicle to be driven at any speed below the set limit. Additionally, it features a top-end speed limiter that sets a maximum speed limit upon installation and prevents the vehicle from being driven above that speed. Having a cruise control system installed in your vehicle is highly recommended. If you’re wondering how to purchase and install one, it typically takes about 2-4 hours to install depending on the make, model, and year of your vehicle. However, some vehicles may take longer to install depending on their physical and electronic accessibility.

What’s included in the box:

• Cruise control computer: This computer is pre-programmed specifically for your vehicle, ensuring compatibility and optimal performance.
• Computer wiring loom: This wiring loom provides power to the cruise control computer and also connects to your vehicle’s speed pulse, brake switch, clutch switch or CANBUS connection. It ensures seamless integration of the cruise control system with your vehicle’s existing electronics.
• T-Harness: The T-harness is a plug-in connection to the throttle pedal. It allows the cruise control system to control the throttle and maintain a consistent speed, giving you a comfortable and stress-free driving experience.
• Command module: The command module is the interface between you and the cruise control system. It comes with a GC3 standard stalk, but you have the option to upgrade to GC4 or GC5 stalks when making your purchase. With the command module, you can easily set and adjust your cruising speed, as well as turn the system on and off.

Cruise control safety features:

• Before activation, the cruise control system must detect resistance across the brake circuit. If there is a fault in the brake lights or brake switch, the cruise control will not work.
• The system also automatically deactivates if the speed increases or decreases by more than 15% of the set speed, such as when driving up a steep hill and the vehicle cannot maintain the set speed in the current gear.
• It’s important to note that the throttle pedal connection only affects the working of the vehicle when the cruise control power is turned on. When the cruise control is turned off, the pedal signals are unchanged, allowing the throttle pedal to operate normally.
• Additionally, the cruise control will automatically deactivate when the brake or clutch is applied, further enhancing the safety features of the system.

General installation process – Lexus CS-350 2011-2014

The installation process for a cruise control system usually takes around 2-4 hours, depending on the make, model, and year of the vehicle. Some vehicles may require more time due to physical and electronic accessibility issues.

To install the system, you’ll need to remove the knee-trim and steering column cowling to access the area under the dashboard and the steering column. You’ll then need to use soldered joints to connect the +ve and CANBUS connections. Next, you’ll need to install the clutch switch and connect it to the cruise computer. Unplug the throttle pedal connector and place the T-harness inline. Connect the other end of the T-harness to the cruise computer. Once the hardware installation is complete, install the command module to the steering column cowling. Make sure to mark the best position before removing the trim. Run the cabling and connect it into the main computer loom. Finally, the setup procedure is straightforward and doesn’t require any additional equipment. The information needed to communicate with the vehicle is pre-installed by Conrad Anderson, so all that is required is to allow the vehicle to access the information.

The static setup procedure for cruise control installation typically involves two steps: pedal setup and CAN search.

• The pedal setup involves calibrating the cruise control to learn the throttle pedal signals of the specific vehicle. This is done by pressing the set button on the command module and then gradually pressing down on the throttle pedal until it reaches its maximum position. The cruise control then learns the range of signals from the pedal and stores them for future use.
• The CAN search involves the cruise control computer searching for and matching the installed software to the specific vehicle make and model. This is done by pressing and holding the set and resume buttons on the command module simultaneously for a few seconds. The cruise control will then display the software version and will search for the appropriate software for the vehicle.

After completing the pedal setup and CAN search, it is recommended to take the vehicle on a short drive to test the cruise control and ensure that it is working correctly.

Command module functions:

The GC3 is the basic stalk that is included in the product price, and it comes with all the basic functions, including setting the current speed, increasing and decreasing speed, coasting (which deactivates the cruise and can also be done by pressing the brake or clutch pedal), and resuming the previous speed.

In addition to these functions, the alternative command modules also include preset speed memory buttons. These buttons allow the driver to set and change specific speeds at any time. These speeds are non-volatile, meaning they remain set even after the ignition is turned off.

• GC4 – 2 preset memories
• GC5 – 3 preset memories (new design)

Command module installation:

Installation of the command module is straightforward. The stalk is bolted to the steering column cowling, with wiring running through the center of the hollow mounting bolt to the main computer wiring loom. The wires are supplied non-terminated to allow them to be run through the drilled cowling. Once the wires are in place, the connector is connected to the pre-pinned cables. It’s important to mount the module in a location that provides enough space to the rear of the cowling for the securing nut and flanged washer. The final position of the stalk can be adjusted using the integral ball joint.

If the cruise control is not working properly, here are some troubleshooting steps to take:

• Check the power supply and main fuse for the command module. If the module isn’t lighting up, this could be the issue.
• Check the brake connection using diagnostic mode. If the module indicator light doesn’t change from green to red, there may be an issue with the brake circuit.
• Check that the brake lights are operational. The cruise control system requires resistance across the brake circuit, so if the brake lights or brake switch is faulty, the cruise control will not work.
