| 15-001/22 | 2022-02-04. Service bulletin. LANE DEPARTURE: BLIND SPOT DETECTION; LANE DEPARTURE; ELECTRICAL SYSTEM; EQUIPMENT. Some vehicles equipped with Blind Spot Monitoring (BSM) may experience a BSM indicator light on the outer door mirror, even if there is no vehicle in the alert (blind spot) area. NOTE: This concern occurs only after a cold start. As the BSM control module temperature rises, the BSM system returns to normal operation. Due to BSM control module production variances, a false detection may occur in some units when the BSM temperature in the control module has not yet reached normal operating temperature. To eliminate this concern, the control logic of the BSM control module has been modified. |
