Front View Camera Module Learn

Calibration

Note:

  • Do NOT swap cameras between vehicles. This is not an approved procedure and will result in a VIN mismatch.
  • After replacement of the B174W Frontview Camera – Windshield and SPS programming, a current DTC may be set in the B174W Frontview Camera – Windshield. This is normal and is an indication that the 174W Frontview Camera – Windshield does not have a currently learned calibration. Continue with this calibration procedure. Upon successful completion of the calibration, the DTC will transition to a history DTC and can be cleared.

The calibration process for the B174W Frontview Camera – Windshield is necessary any time the module is removed from it’s bracket, or the windshield glass has been replaced. This includes replacement of the B174W Frontview Camera – Windshield, as well as any time the module is removed for diagnosis or windshield replacement. Any maintenance, repair, or part replacement that impacts the vehicle ride height will also require frontview camera calibration. When the correct driving conditions are met, this process can be completed within 3–5 minutes. If conditions are not met, the B174W Frontview Camera – Windshield will continuously run the calibration until successfully completed. This calibration will work across ignition cycles and is not required to be re-initialized at start up. If the lane departure warning switch is pressed during calibration, the lane departure warning switch indictor will flash momentarily and then remain not illuminated. This is normal operation.

The calibration procedure may start automatically after SPS programming is complete. During this time the amber Lane Departure Warning indicator on the P16 Instrument Cluster will illuminate.

To calibrate the B174W Frontview Camera – Windshield, 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.)

If calibration does not begin automatically after SPS programming or if any diagnostic procedure requires calibration to be performed, perform the following with a scan tool to begin the calibration procedure:

  1. Apply the parking brake.
  2. Place the transmission in Park (if applicable)
  3. Install scan tool
  4. Select B174  Frontview Camera
  5. Select Configuration/ Reset Functions
  6. Select the Frontview Camera Learn and follow the directions displayed on the screen.
  7. Drive the vehicle to complete calibration.

If Slow to Calibrate

The ideal calibration condition is driving on a 2 lane divided highway with markings on both sides of the lane. One or more of the following conditions may increase the length of time required to complete the calibration procedure:

  • Heavy traffic
  • Stop and go traffic
  • Mountain roads
  • Curves in roadway
  • Poor contrast lane markings
  • Botts Dots type lane markings
  • Operating the vehicle at speeds greater than recommended
  • Driving through snow or fog, or driving directly into the sun
  • B174W Frontview Camera – Windshield not properly installed – Verify the camera is fully snapped into the bracket tabs and is secure
  • Incorrect windshield – Some aftermarket windshields may have the B174W Frontview Camera – Windshield bracket installed in the incorrect location or may have incorrectly installed film that partially blocks the camera field of view

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
  • B174W Frontview Camera – Windshield not properly installed – Verify the camera is fully snapped into the bracket tabs and is secure
  • Incorrect windshield – Some aftermarket windshields may have the B174W Frontview Camera – Windshield bracket installed in the incorrect location or may have incorrectly installed film that partially blocks the camera field of view
