Calibration Procedure

  1. Verify no other DTCs, except for DTC U3000 55, are set.
    • Go to next step: If no other DTCs are set 
  2. Prior to driving the vehicle make sure the surface in front of the B233B Forward Range Radar Sensor - Long Range is clean. Also, verify the mounting area is not damaged and allows the B233B Forward Range Radar Sensor - Long Range to face the intended direction.
  3. Prepare the scan tool to be mobile for Long Range Radar Calibration driving phase. The scan tool needs to stay connected during the driving phase of the calibration.
  4. Engine running.
    5. NOTE:

    Once calibration has begun, do not back out of screen or press any other buttons on the scan tool until the calibration is complete.

    NOTE:

    Vehicle speed must be less than 10 km/h (6 mph) before initiating the Forward Range Radar Sensor - Long Range Learn.

  5. Select Long Range Radar Sensor Module Learn on the scan tool and follow any on-screen instructions. The driver information center will display the FORWARD COLLISION ALERT message during calibration.
  6. Drive the vehicle within the following conditions for 15 - 30 minutes or until calibration is complete. The FORWARD COLLISION ALERT message will turn off when calibration is complete.
    • Drive at speeds greater than 40 km/h (25 mph).
    • Minimize tight curves.
    • Avoid extreme acceleration or deceleration.
    • Follow one or multiple vehicles. Typical vehicle traffic is sufficient, but vehicles 30 - 50 m (100 - 165 ft) away are most effective at decreasing the calibration time.
    • Drive in on a urban/city road that has stationary objects on the side of the road (street signs, guard rails, mail boxes, fences, etc.).
  7. Verify proper calibration by observing that the FORWARD COLLISION ALERT message turns off within 15 - 30 minutes of normal driving.
    • If the FORWARD COLLISION ALERT message fails to turn off 

      Refer to If Slow to Calibrate below and repeat the calibration procedure following recommended operating conditions.

    • Go to next step: If the FORWARD COLLISION ALERT message turns off 
  8. Drive at speeds greater than 40 km/h (25 mph) and verify engagement of adaptive cruise control.
    • If adaptive cruise control will not engage 

      Check vehicle for DTCs and correct as required.

    • Go to next step: If adaptive cruise control engages 
  9. All OK.
