厂商摘要

以下为英文原文

Some customers may complain about one or more warning lights ON when they start the vehicle during hot weather. The following DTC is stored in memory: U3000:98 - Forward sensing camera (FSC) stops functioning due to temporary high temperature. The combination of warning lights mentioned by the customer may include: SCBS/SBS LAS/LDWS HBC Master Warning Light Instrument Cluster Multi-Information Display (if equipped) warning messages may include: Forward Smart City Brake Support Malfunction. Smart Brake System Malfunction. Front Camera Sensor System Malfunction. MAZDA CONNECT center display warning messages may include: High Beam Control [HBC] / Lane-keep Assist System [LAS] Malfunction. Have the vehicle checked by a dealer if this indicator stays on. Smart City Brake Support [SCBS] Malfunction. Have the vehicle checked by a dealer immediately. Note: The center display Warning Messages are only displayed when the customer selects Applications>Vehicle Status Monitor>Warning Guidance>Warnings. This condition may be caused by the FSC not being durable enough in high temperatures. [Earlier production Mazda3, Mazda6, CX-3 and CX-5 until summer 2017] The warning lights may stay on and these functions are deactivated until the ignition switch is turned off. Both U3000:98 (FSC) and U3000:04 (FSC) are stored. U3000:04 - Forward sensing camera (FSC) internal malfunction. If only U3000:04 (FSC) is stored, this TSB does not apply. This condition may be caused by FSC control logic that is too sensitive. When the FSC detects DTC U3000:98 during high temperature, it stops the internal communication and stores DTC U3000:04. DTC U3000:04 will not clear and SCBS/SBS, LAS/LDWS, and/or HBC functions will not resume until the ignition switch has been turned OFF even if the temperature of the FSC cools.
