Fig. 16: Identifying Rear Object Sensor Housing

  1. Remove rear bumper fascia. Refer to Rear Bumper Fascia Replacement .
  2. Disconnect electrical from the rear object sensor.

NOTE: The rear object sensor is a one piece design. Do NOT twist the sensor cap to try and remove the painted cap. Replacement sensor requires painting to match fascia/bumper body color.

  1. Lift the locking tabs on the housing and remove the rear object sensor.

Installation Procedure

NOTE: Do not refinish previously painted sensors. Excess paint build up will cause the sensor to be inoperative.

  1. Paint the rear object sensor. Refer to Basecoat/Clearcoat Paint Systems .
  2. Ensure the paint does not exceed 6 mils. Use a paint thickness gauge suitable for non-ferrous metals.

    Refer to Paint Gauges .

NOTE: Ensure the silicone decoupling ring is installed on the sensor to avoid sensor failure.

  1. Insert the sensor into the housing.
  2. Connect the electrical connector to the rear object sensor.

FRONT VIEW CAMERA MODULE CALIBRATION

The calibration procedure will start automatically after SPS programming is complete. If calibration does not start automatically or if manual initialization is desired, calibration can be initiated by selecting Frontview Camera Learn in the scantool. During this time the Lane Departure Warning amber indicator will illuminate.

Calibration

The calibration process for the front view camera system is necessary when a front view camera module is replaced by a new one. This process shall not be required when only replacing the windshield and the front view camera module has been mounted again properly. This process shall be completed within 3-5 minutes when the correct driving conditions are met. If conditions are not met correct, the front view camera module shall continuously run the service point calibration until successfully completed. This process shall work across ignition cycles and shall not be required to be re-initialized at start up. If the Lane Departure Warning Switch is pressed during calibration, the indictor will flash momentarily and then stay out - this is normal operation.

To calibrate the front camera, operate the vehicle in the following conditions until the calibration is complete:

  • Clean windshield.
  • Avoid lane changes.
  • Maintain vehicle speeds between 56-90 km/h (35-56 MPH).
  • Ensure the road contains visible references (well defined lane markings, curbs, etc.).

Once the procedure is complete, the amber indicator will turn off. Shortly after the green ready to assist light should turn on as long as all conditions are met for normal operation. The system is then ready to assist.

If Slow to Calibrate

One or more of the following conditions may increase the length of time required to complete the selfcalibration procedure:

  • Heavy traffic
  • Stop and go traffic
  • Mountain roads
  • Curves in roadway
  • Poor contrast lane markings
  • Botts' Dots type lane markings
  • Operating the vehicle speed is greater than 90 km/h (56 MPH)
  • Driving through snow or fog, or driving directly into the sun
  • Camera not properly installed. Verify it is snapped into tabs and is secure. Refer to Front View Camera Replacement (Encore) .

No Calibration

Conditions that will prevent completion of the self-calibration procedure:

  • Dirty windshield glass or obstruction on windshield
  • Operating the vehicle with speed less than 56 km/h (35 MPH)
  • No visible lane markings
  • Severe weather where lane markings cannot be seen
  • Camera not properly installed. Verify it is snapped into tabs and is secure. Refer to Front View Camera Replacement (Encore) .
