The Park Assist Module (PAM) (also known as the ParkTronic System/PTS module) (1) is secured with two push-in plastic fasteners through two mounting tabs (3) integral to the module housing on the lower inner deck lid opening reinforcement below the right rear lamp unit housing. The module is concealed behind the lower deck lid opening sill inner trim. Concealed within the molded plastic PAM housing is a microprocessor and the other electronic circuitry of the module. The module housing is sealed to enclose and protect the internal electronic circuitry. The module software is flash programmable.
Two connector receptacles (2) containing terminal pins are integral to the downward-facing side of the housing. The module is connected to the vehicle electrical system through two dedicated take outs and connectors of the body wire harness.
The PAM cannot be adjusted or repaired and, if damaged or ineffective, it must be replaced with a new unit.
- Position the Park Assist Module (PAM) (2) (also known as the ParkTronic System/PTS module) to the right side of the lower deck lid opening inner reinforcement panel (1) below the right tail lamp within the trunk.
- Reinstall the two plastic push-in fasteners (3) that secure the PAM to the lower deck lid opening inner reinforcement panel.
- Reconnect the two body wire harness connectors to the PAM connector receptacles (4).
- Reinstall the trunk side trim onto the right side of the lower deck opening inner reinforcement panel within the trunk. Refer to «PANEL, TRUNK TRIM, INSTALLATION»(ref-646233-S11107010512014072800000) .
- Reinstall the trim panel onto the lower deck lid opening sill in the trunk area. Refer to «CARPET, FLOOR, INSTALLATION»(ref-646233-S00332336212014072800000) .
- Reconnect the negative cable to the battery.
Note. If this Electronic Control Unit (ECU) is being replaced with a new unit, a diagnostic scan tool MUST be used to align the PROXI configuration data into the new ECU. Follow the routine outlined in the diagnostic scan tool for PROXI Configuration Alignment under Body Control Module (BCM) Miscellaneous Functions menu.

Vehicles equipped with the optional Blind Spot Monitor (BSM) system have two primary components. These components are the two RAdio Detection And Ranging (RADAR) blind spot sensors (1) (also known as the Left or Right Blind Spot Sensors/LBSS or RBSS). In this vehicle, each sensor also includes an internal microcontroller and control circuitry that monitors and controls both the sensor and the blind spot display for the same side of the vehicle. This explains why the sensors are sometimes referred to as smart sensors.
Each sensor with control circuitry is contained and protected within a molded plastic case that includes an integral connector receptacle (2) at one end. The sensors are each connected to the vehicle electrical system through a dedicated take out and connector of the rear bumper fascia wire harness. The two sensors are concealed behind the outboard ends of the rear bumper fascia. Each sensor is snapped into a dedicated molded plastic mounting bracket that is permanently affixed to the inside surface of the fascia just behind the left and right rear wheel openings.
The blind spot sensors and control circuitry cannot be adjusted or repaired. If a sensor is damaged or ineffective, it must be replaced with a new unit. The sensor module software is flash capable. The mounting bracket for each sensor is serviced only as a unit with the rear bumper fascia.
Note. Be certain that both the Left Blind Spot Sensor (LBSS) and the Right Blind Spot Sensor (RBSS) part numbers are at the same revision level. The Blind Spot Monitor (BSM) system will not function or will not function properly if the revision levels of the LBSS and the RBSS part numbers are not synchronized.
- Position the Left Blind Spot Sensor (LBSS) or Right Blind Spot Sensor (RBSS) (3) to the mounting bracket on the rear bumper fascia (1).
- Using hand pressure, press the LBSS or RBSS firmly and evenly into the mounting bracket until the latch tabs (2) are fully engaged.
- Reconnect the rear bumper fascia wire harness connector (4) to the LBSS or RBSS connector receptacle.
- Reinstall the rear bumper fascia onto the vehicle. Refer to «FASCIA, REAR, INSTALLATION»(ref-646214-S21494098532014072800000) .
- Reconnect the negative cable to the battery.
Note. If this Electronic Control Unit (ECU) is being replaced with a new unit, a diagnostic scan tool MUST be used to align the PROXI configuration data into the new ECU. Follow the routine outlined in the diagnostic scan tool for PROXI Configuration Alignment under Body Control Module (BCM) Miscellaneous Functions menu.

Vehicles equipped with the rear park assist system have four park assist sensors (1) installed on the rear bumper fascia. Only the membrane (3) of each sensor is visible through a hole in the outer vertical surface of the fascia. The remainder of each sensor including the sensor mounting bracket, the sensor spacer (also known as the O-ring or decoupling ring) and the sensor wiring connection is concealed behind the fascia. A sensor wire harness behind the fascia connects the sensors to the vehicle electrical system.
Each of the four sensors is identical in construction and is interchangeable. The electronic circuitry and a communication chip for each sensor is enclosed and protected within the molded black plastic sensor housing. The housing includes an integral connector receptacle (4) and two integral latch tabs (2). The sensor membrane extends from the surface of the sensor housing, and is finished to match the outer surface of the fascia.
Scheme 8
The numbering system for the park assist sensors allows for up to twelve sensors on the vehicle, six front and six rear. The sensors are numbered in a clockwise manner starting at the left front bumper. The left front sensor (if the vehicle were equipped with front park assist) is the number 1 sensor. The numbering continues in a clockwise direction around the vehicle. Since this vehicle uses only four rear sensors, sensor numbers 7 and 12 are omitted, so the left rear sensor is the number 11 sensor.
A resilient O-ring spacer (also known as a decoupling ring) around the circumference of the membrane isolates the membrane from the openings in the fascia. Each sensor is snapped into its own dedicated molded plastic mounting bracket. Each sensor mounting bracket is heat-staked to the back side of the rear bumper fascia.
The park assist sensors cannot be adjusted or repaired. If a sensor is ineffective or damaged it must be replaced with a new unit. The sensor spacers are available for individual service replacement. The sensor mounting brackets are serviced only as a unit with the rear bumper fascia.
Note. The park assist sensors (1) and the resilient sensor spacers (2) (also known as decoupling rings or O-rings) are each available for separate service replacement. The sensor brackets (3) are bonded to and integral to the back side of the rear bumper fascia (4).
- Engage the O-ring spacer (2) around the circumference of the sensor membrane protrusion. NOTE: Production and all service replacement O-ring spacers are tapered. The wide side (base) of the O-ring should be seated against the sensor housing and the narrow side should be oriented toward the outer surface of the sensor membrane and the rear fascia.
- Align and insert the sensor (1) into the sensor bracket (3) behind the rear bumper fascia (4) until the bracket latch features are fully engaged over the latch tabs of the sensor. NOTE: Be certain that each sensor membrane is properly centered in the openings of the rear fascia and that the resilient O-ring spacers are not pinched. Improper centering or pinched O-rings can be detrimental to proper park assist sensor operation. Be certain that the sensor membrane is flush with the outer surface of the fascia.
- From behind the rear fascia, reconnect the wire harness connector to the sensor connector receptacle.
- Reinstall the rear bumper fascia onto the vehicle. Refer to «FASCIA, REAR, INSTALLATION»(ref-646214-S21494098532014072800000) .
- Reconnect the negative cable to the battery.

The park assist Off switch is a virtual push button (also known as a soft key) integral to the instrument panel Integrated Center Stack (ICS) display (1), also known as the Uconnect™ Touch screen module. The park assist system can be manually disabled or enabled using the Uconnect™ Touch screen module controls found under the Settings tab of the display.
The Uconnect™ Touch screen module cannot be adjusted or repaired and, if the park assist Off switch function is ineffective or damaged, the entire ICS display must be replaced with a new unit. Refer to MODULE, INTEGRATED CENTER STACK SCREEN, REMOVAL .
