Symptom/Vehicle Issue: Blind Spot Or Park Assist Warnings, False Activation
Customer Complaint/Technician Observation: Owner complains the blind spot warning
lamps stay on while driving or stay on longer than they should or park assist system warnings occur
without objects being present. Technician has observed the conditions as described, vehicle may or
may not have active DTC’s during the inspection.
Discussion: Closely inspect the rear fascia covering area for any noticeable body work
in the general area of the blind spot mounting locations behind the fascia covering.
To avoid false detections from radar sensors (lane change assist/blind spot detect),
always inspect the rear fascia covering for body service repairs.
1. The layer of paint before and on the sensor locations must not exceed OEM
thickness standards
2. A repair of the plastic must not be carried out within 25 cm of this mounting area.
3. Filler must not be applied within 25 cm of this area. Three-coat painting upon the
repaired areas of the bumper cover can contribute to false detections/warnings.
If the complaint is regarding the park assist system warnings that appear to be inaccurate;
closely inspect the sensor mounting trim rings to ensure sensors are evenly aligned with
the trim ring and any painted sensors do not have excessive paint from a potential recent
body repair. Fig 1, examples for blind spot sensor mounting (behind fascia) and park
assist sensor centering within trim ring.
