2. Bend the retaining tabs down behind the headliner. see scheme 3
3. Raise the headliner in the rear of the vehicle in the liftgate opening «(Refer to BODY/INTERIOR/HEADLINER - INSTALLATION)»(ref-248887-S04541608782007022700000).
4. Close liftgate.
5. Connect the battery negative cable.
6. Close hood.

Scheme 5

The Park Assist Module is located on the left side of the vehicle, behind the quarter trim panel, just behind the C-pillar. (Scheme 5)and (Scheme 6). It is has a molded plastic housing which housing internal circuitry and one electrical connector. There are two mounting tabs that affix the module to the left inner quarter panel with two screws.

Scheme 6

The module has a number of functions

1. Supply voltage to the sensors and display.
2. Disconnection of the display with bus idle and over voltage Vmax.
3. Triggering the sensors.
4. Analyze echo delay times and calculate obstacle distances.
5. Bi-directional data communication to the display for diagnosis.
6. System diagnostics - diagnosis and error handling (sensors, display, module).
7. Data exchange over the Programmable Communication Interface (PCI) data bus.

1. Position the Park Assist Module and install the two attaching screws. see scheme 7 Torque screws to 3.5 N.m (30 in. lbs.).
2. Connect the Park Assist Module electrical connector. see scheme 6
3. Install the left quarter trim panel «(Refer to BODY/INTERIOR/QUARTER TRIM PANEL - INSTALLATION)»(ref-248887-S20438406012007022700000).
4. Connect the battery negative cable.

Scheme 7

The Park Assist Sensors are located in the rear bumper fascia mounted equally apart. (Scheme 7)and (Scheme 8). The sensors generate ultrasonic pulses when triggered by the park assist module when an obstacle is detected. The sensors then signal the module when reflected ultrasonic pulses are received.

Scheme 8

The sensors detect objects with an ultrasonic pulse that reflects off the object and then is sent to the module to determine the distance of the object.

1. Position the Park Assist Sensor over the retaining housing and firmly snap into housing in rear fascia.
2. Install the rear fascia «(Refer to FRAME & BUMPERS/BUMPERS/REAR FASCIA - INSTALLATION)»(ref-248897-S40320818372007022700000) .
3. Connect the battery negative cable.
4. Close hood.
5. Verify vehicle and system operation.
