Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Module, Local Interface Network (Lin): Description
The Local Interface Network (LIN) module (1) is a LIN slave node located within the right horizontal spoke of the steering wheel, behind the spoke bezel. This module is used on all vehicles not equipped with the optional speed control (also known as cruise control) system. On vehicles equipped with optional speed control, the LIN module is integral to the speed control switch pod. The entire LIN module including its mounting provisions and its electrical connection are concealed beneath the spoke bezel. There are no visible components of the module above the steering wheel spoke bezel.
The LIN module housing is constructed of molded black plastic. The module and a mounting adapter plate are secured through three integral mounting tabs (2) and a molded plastic mounting adapter plate to mounting bosses on the back of the spoke bezel by three screws. The mounting adapter plate is also secured to the steering wheel spoke by a single screw installed through a clearance hole in the rear trim cover of the steering wheel, and by two screws within the steering wheel hub cavity. A connector receptacle (3) integral to the inboard end of the module housing connects the LIN slave node circuitry to the vehicle electrical system through a dedicated take out and connector of the steering wheel wire harness.
The LIN module cannot be adjusted or repaired. If the module or any function of the LIN slave node is ineffective or damaged, the entire LIN module unit must be replaced.
