Calibration of the front mounted radar may require which of the following?

• A. All of the Above
• B. Visual inspection
• C. Tire pressure
• D. Steering angle

Answer: (A)

Calibrating a front-mounted radar depends on accurate physical conditions and a clear sensor view. The radar uses the vehicle’s geometry as a baseline, so anything that changes ride height, wheel alignment, or sensor visibility can throw off the calibration. Visual inspection ensures the radar housing and bumper are free from damage, dirt, or obstructions that could distort readings. Tire pressure matters because incorrect pressures change the vehicle’s stance and ride height, which shifts the radar’s reference position. Steering angle is crucial because calibration assumes the steering wheel is centered and the wheels are pointing straight ahead; if the steering angle isn’t within tolerance, the reference geometry is off and calibration won’t be accurate. Since all of these factors can affect calibration, the correct option is that all of the above are required.
