The SCCM includes the steering column shroud (1), the Steering Angle Sensor (SAS) (2), the clockspring (3), the multi-function switch (6), a steering column power tilt and telescope switch (5) for vehicles so equipped and a trim cover (4).

The SCCM is secured to the steering column by a unique mounting system using no external fasteners. The SCCM has two key stone features that snap into slots in the upper column jacket to secure the SCCM. In addition, a mechanical red indicator on the lower surface of the column shroud will be flush with the shroud surface when the SCCM is properly installed, but will stand proud of the shroud surface if the key stones are incompletely or improperly seated in the slots of the column jacket.

There are also unique lugs cast into the outer circumference of the steering wheel hub that must be engaged into slots within the inner circumference of the clockspring rotor hub to unlock and drive both the clockspring and the SAS, and the steering wheel must be tightened to specification to ensure proper clockspring and SAS function.

The SCCM includes an integral connector receptacle that faces toward the instrument panel and is connected to the vehicle electrical system through a single take out and connector of the instrument panel wire harness. The instrument panel wire harness take out has been intentionally provided with additional length to facilitate service removal and installation of the SCCM. However, following SCCM installation, this additional length must be pulled back and secured to the instrument panel structure to prevent the potential for undesirable rattling and buzzing noises while driving.

The SCM cannot be adjusted or repaired. If ineffective or damaged the entire SCCM unit must be replaced.

The transmission control module (TCM) (2) and mounting bracket (1) is mounted under the center dash panel, on the transmission hump.

The electronic control system consists of various components providing inputs to the TCM. The TCM monitors transmission sensors, shifter assembly, and bus messages to determine transmission shift strategy. After shift strategies are determined, the TCM controls the actuation of transmission solenoids, which controls the routing of hydraulic fluid within the transmission, by moving a sequence of four valves to make a shift occur.

The system performs its functions based on continuous real-time sensor feedback information. In addition the TCM receives information from the rest of the vehicle over the CAN C bus. The CAN C bus is a high-speed communication bus that allows real time control capability between various controllers. Most messages are sent every 20 milliseconds. This means critical information can be shared between the transmission, engine, and ABS controllers. The CAN C bus is a two wire bus with a CAN C Bus (+) circuit and a CAN C Bus (-) circuit. These circuits are twisted pairs in the harness to reduce the potential of radio and noise interference.

The transmission control system automatically adapts to changes in engine performance, vehicle speed, and transmission temperature variations to provide consistent shift quality. The control system ensures that clutch operation during up-shifting and downshifting is more responsive without increased harshness. The TCM activates the solenoid valves and moves valves in the valve body to achieve the necessary gear changes. The required pressure level is calculated from the load condition, engine speed. Vehicle speed (from ABS module) and transmission oil temperature, matched to the torque to be transmitted. Power for the transmission system is supplied through the shifter mechanism (no transmission control relay).

10. Connect the battery negative cable.

Note. On vehicles equipped with the Sentry Key Immobilizer System (SKIS), when the Wireless Ignition Node (WIN) is replaced with a new unit, a diagnostic scan tool MUST be used to initialize the new WIN and to program at least two Sentry Key FOBIK transponders before the vehicle can be operated. Refer to STANDARD PROCEDURE .

Note. Vehicles equipped with PEM: If the WIN is being replaced, a diagnostic scan tool MUST be used to initialize and configure the new PEM. Follow the programming steps outlined in the diagnostic scan tool for Replace found under Miscellaneous Functions for the PEM/Passive Entry Module menu item.

Note. On vehicles equipped with a premium Tire Pressure Monitoring (TPM) system, when the Wireless Ignition Node (WIN) or the spare tire pressure sensor is replaced with a new unit, a diagnostic scan tool MUST be used to run a routine that allows the WIN to be programmed with the ID number and location of the spare tire pressure sensor mounted in the wheel of the spare tire. This may be done using a TPM-RKE Analyzer special tool by following the programming steps outlined in the diagnostic scan tool for Program Tire Sensor ID w/TPM Tool under Miscellaneous Functions for the WIN menu item. If a TPM-RKE Analyzer special tool is not available, the spare tire must be dismounted from its wheel to access and note the ID number on the spare tire pressure sensor so that the ID code for that sensor can be programmed into the new WIN. Follow the programming steps outlined in the diagnostic scan tool for Learn Spare Tire Sensor ID under Miscellaneous Functions for the WIN menu item as appropriate. Refer to SENSOR, TIRE PRESSURE MONITORING (TPM), INSTALLATION .

Note. On vehicles equipped with a shaft lock module the WIN initialization procedure is required whenever the WIN or shaft lock module is replaced. Refer to STANDARD PROCEDURE .

The adaptive speed control sensor (1) (also known as the Adaptive Cruise Control/ACC sensor or module, or the radar sensor or module) is located on a bracket secured near the center of the underside of the front bumper support member of the Front End Module (FEM) behind the front fascia. The stamped steel ACC sensor mounting bracket is secured by two screws to a bracket on the bumper support member. This sensor is also the primary component of the Forward Collision Warning (FCW) feature of the Electronic Vehicle Information Center (EVIC).

One fixed ball stud (4) and two adjustable ball studs (3) secure the sensor housing through a snap fit into three molded plastic ball socket clips installed in the mounting bracket. The sensor pivots on the fixed ball stud while the two adjustable ball studs allow the sensor to be vertically aligned after installation using an ACC vertical alignment special tool and a 3.5 millimeter hex nut driver special tool. Horizontal alignment is performed electronically using a diagnostic scan tool during a ten minute drive at a steady, predetermined speed following completion of the vertical alignment.

The ACC sensor electronic circuitry is sealed and protected within a die cast aluminum housing. A molded plastic cover and a lens or radar dome (5) faces forward through an opening in the center of the front fascia lower airflow grille texture that is trimmed with a bezel snapped into the texture opening. A molded plastic sensor bezel or mirror cover with a center clearance hole for the sensor lens snaps over the sensor and conceals a small square mirror in one corner of the sensor cover that is used for calibration purposes during the sensor manufacturing process.

The ACC sensor includes an applied connector receptacle (2) that is sealed and secured to the sensor housing with screws and faces downward when installed on the mounting bracket. The ACC sensor is connected to the vehicle electrical system through a single dedicated takeout and connector of the FEM wire harness.

The adjustable ball studs and the ACC sensor cannot be repaired. If ineffective or damaged the entire sensor unit must be replaced. The three plastic ball socket clips in the sensor mounting bracket must also be replaced each time the ACC sensor is removed from and reinstalled onto the mounting bracket.
