OEM ADAS Radar Optimized Color Resources: Nissan

Changes in advanced driver assistance systems (ADAS) radar technology are introducing new refinishing considerations. Paint film thickness not only may affect the performance of ADAS radars, color formula selection may also be a contributing factor. What resources do repairers have available? Let’s see what Nissan has to say.

Nissan provides the Ariya Bumper Refinishing Requirements position statement. This document offers precautions for repairability of the bumper covers, including a chart of paint maker product lines that are approved for refinishing a bumper cover per color code.

When researching a 2023 Nissan Ariya service information a statement is found under Cruise Control & Driver Assistance ➤ Cruise Control System ➤ ProPilot Assist 2.0 ➤ System Description ➤ Handling Precaution ➤ Precautions For ProPilot Assist 2.0:

"If an improper repair is performed on the bumper (for example, application of putty made from different materials, repaint, etc.) the radar signal could be weakened or prevented from functioning properly. This may cause the radar sensor not to detect objects correctly. Improper repair may result in serious personal injury."

More precautions for refinishing bumpers are found under: Body Exterior, Doors, Roof & Vehicle Security ➤ Exterior ➤ Removal And Installation ➤ Front Bumper ➤ Inspection.

Nissan states:

  • "Only the body exterior paint color, which are adopted for this model, painting can be constructed. (Do not paint more thickness than necessary)"
  • "Only the approved paint suppliers, products and color formulator can be constructed"

Nissan also provides precautions when only clearcoat is applied near the side radars.

Within the bumper inspection document Nissan provides charts and illustrations to describe permittable repairs and measurements to identify the irradiation area of the side radar.

Improper color selection may cause ADAS to malfunction and potentially fail. Check OEM repair information to identify what restrictions may apply to the repairs you are considering. Always verify that the ADAS is functioning properly after completing repairs.
