A positive value indicates an offset to the left of the vehicle’s longitudinal axis (driver’s side) and a negative value indicates an offset to the right of the vehicle’s longitudinal axis (passenger side). The offset range is ± 500 mm (19.69 inches). The physical mounting location of the sensor cannot exceed ± 500 mm.
Following Distance Settings Creating Data Log Report The following distance / alerts configuration number is a numeric value that represents the current configuration of the ACB sensor following distance setting and alerts.
