Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Calibration Procedure
- Verify no other DTCs, except for DTC U3000 55, are set.
- If other DTCs are set
Diagnose any other DTCs first. Refer to Diagnostic Trouble Code (DTC) List - Vehicle .
- Go to next step: If no other DTCs are set
- If other DTCs are set
- 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.
- 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.
- Engine running.
- Select Long Range Radar Sensor Module Learn on the scan tool and follow any on-screen instructions. The driver information center will display the SERVICE DRIVER ASSIST message during calibration.
- Drive the vehicle within the following conditions for 10 - 30 minutes or until calibration is complete. The SERVICE DRIVER ASSIST message will turn off when calibration is complete.
- Drive at speeds greater than 56 km/h (35 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 an environment that has stationary objects on the side of the road (street signs, guard rails, mail boxes, fences, etc)
- Verify proper calibration by observing that the SERVICE DRIVER ASSIST message turns off within 10 - 30 min of normal driving.
- If the SERVICE DRIVER ASSIST 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 SERVICE DRIVER ASSIST message turns off
- If the SERVICE DRIVER ASSIST message fails to turn off
- 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
- If adaptive cruise control will not engage
- All OK.
Vehicle must be equipped with factory install grille and emblem. Decorative aftermarket accessories around the grille or emblem may prevent calibration.
Once calibration has begun, do not back out of screen or press any other buttons on the scan tool until the calibration is complete.
