Speed Control Switch - Description

DESCRIPTION




Figure 1 - Except Adaptive Speed Control



Figure 2 - With Adaptive Speed Control
The speed control switch pod (1) is located in the right spoke of the steering wheel spoke bezel. Two different switches are used. One switch has four buttons and is used on vehicles not equipped with the optional adaptive speed control (also known as the Adaptive Cruise Control/ACC) system. The other switch has six buttons and is used on vehicles equipped with the ACC system option. These switches are the primary control used by the vehicle operator to manage the particular speed control system installed in the vehicle. The only visible components of the switch pod are the switch push buttons and a decorative bezel around the push buttons, which stands slightly proud of the steering wheel spoke bezel. The remainder of the switch pod including its mounting provisions and its electrical connection are concealed beneath the spoke bezel.

The switch pod housing and push buttons are constructed of molded plastic. Each of the push buttons has white International Control and Display Symbol graphics or text applied to it, which clearly identify the function of each push button. The switch pod is secured through three integral mounting tabs (2) to mounting bosses on the back of the spoke bezel by three screws. A connector receptacle (3) integral to the inboard end of the switch pod housing connects the speed control switch and the Local Interface Network (LIN) slave node circuitry integral to the switch pod to the vehicle electrical system through a dedicated take out and connector of the steering wheel wire harness.

The speed control switch pod cannot be adjusted or repaired. If any function of the switch or the LIN slave node is ineffective or damaged, the entire switch pod unit must be replaced.
