15-001-262026-06-02. Service bulletin. ELECTRICAL SYSTEM; LANE DEPARTURE: BLIND SPOT DETECTION. DESCRIPTION Some customers may experience that the BSM (Blind Spot Monitoring) warning light remains on while driving, even though no vehicle is present behind. This may be caused by electrical noise in the BSM control module power supply and vibration noise from the rear bumper that falsely detects a vehicle behind. To eliminate this concern, the control software of the BSM has been modified to prevent the influence of noise. Customers having this concern should have their vehicle repaired using the following repair procedure. REPAIR PROCEDURE 1. Verify the customer concern. NOTE: This issue may have two causes: the BSM software not at the latest version and the BSM insufficiently fastened. The issue may occur due to either one or both. Therefore, it is necessary to strictly follow the procedure outlined below. 2. Reprogram ECU with the Mazda Modular Diagnostic System (M-MDS), using Mazda Diagnostic and Repair Software (MDARS). Refer to MDARS ECU Reprogramming Procedure. 3. Remove the rear bumper according to the instructions in MGSS (REAR BUMPER REMOVAL/INSTALLATION).
