Subject:
IMPROPER FRONT PARKING SENSOR OPERATION IN HEAVY RAIN
Bulletin No.: 15-004/19
Last Issued: 09/27/2019
APPLICABLE MODEL(S)/VINS
2018-2019 Mazda6 vehicles with VINs lower than JM1GL******510711 (produced before Aug. 6, 2019)
DESCRIPTION
Some customer's may complain that In heavy rain, the front parking sensor system detects objects despite
nothing being in front of the vehicle, and no related DTCs are stored. This may be caused by the ultrasonics
diffusing inside when the front parking sensors get wet. As a result, the parking assist unit mistakenly
detects objects near the front of the vehicle. To correct this issue, the detecting logic in close range has
been improved.
Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
1. Verify the customer concern.
2. Replace the parking assist unit with modified one according to the instruction on MGSS (PARKING
ASSIST UNIT REMOVAL/INSTALLATION).
NOTE: Explain to the customer that even with the improved parking assist unit, the same symptom may
occur during heavy rain due to the characteristics of the sensor. Refer the customer to “Parking Sensor
System” in the owner's manual.
3. Verify repair.
