Tsb: Sensitive Acura Sensors

This bulletin applies to 2022-2024 Acura RDX and MDX vehicles. Under certain circumstances when reversing near a chain link fence or highly reflective surfaces, a parking and back-up sensor system abnormal message may be displayed in the multi-information display. When the back-up sensors detect a large number of reflected waves, the increased processing load on the sensor may cause a memory processing overload. 

Clear any DTCs and update the parking and back-up sensor system software with the latest version.
