  Summary

  A kick-down switch has been adopted to determine when the customer has fully depressed the throttle pedal for maximum acceleration. A load can be felt while the accelerator pedal is being depressed. When the accelerator pedal is depressed further, the kick-down switch is activated and a click is felt. The driver can control the kick-down by knowing the amount of accelerator depression. An electrical signal is not transmitted by the kick-down switch turning on/off.

  Summary

  Some customers may experience the following symptoms: No sound from some audio sources (AM, FM, SiriusXM®) after turning the ignition on. Radio station selection (AM, FM, SiriusXM®) changes unintentionally after turning the ignition on. Audio source cannot be changed. Diagnosing according to MGSS online does not solve the problem. These concerns may be caused by the remote tuner not operating properly under certain situations. To eliminate these concerns, the remote tuner control software has been modified.

  Summary

  Some customers may complain about color discrepancies (brightness differences) of the image displayed on the screen when using the 360°view monitor. As this phenomenon is not a system failure, do not make any repairs or replace any parts. Explain the cause of this occurrence to the customer as follows: The 360°view monitor is a system that provides a complete picture of the vehicle surroundings by combining the pictures captured by 4 separate cameras. These cameras are installed in the front, rear, right and left sides of the vehicle. Each camera has a color adjustment function (white balance) that operates independently from each other, which can result in color discrepancy when the combined picture is displayed on the screen. This is especially true when one of the cameras captures more green objects than the remaining cameras.

  Summary

  Some customers may complain that the ambient temperature on the instrument cluster is displayed more than 50 °F (10 °C) lower than the actual temperature, resulting in insufficient performance of the air conditioning. This is caused by inappropriate soldering in the ambient temperature sensor. To eliminate this concern, the soldering process has been enhanced at the supplier.

  Summary

  Some technicians may notice an oil seepage from the A/T at the thermo valve when the vehicle under covers are removed. This is caused by insufficient tightening torque of the thermo valve. To eliminate this concern, the tightening torque of the thermo valve has been modified from 52-59 ft-lbs (70-80 N·m) to 63-71 ft-lbs (86-96 N·m). Technicians seeing this concern should repair the vehicle using the following repair procedure.

  Summary

  SSPD6 - SPECIAL SERVICE PROGRAM - VEHICLE CONTROL MODULE (VCM) PROGRAMMING - 2024 CX-90 SSPD6 - 2024 CX-90 - Vehicle Control Module (VCM) Reprogramming: This campaign will resolve three different concerns. Unintentional warning or braking when backing up. When backing up the vehicle in a parking lot or similar area, the View Monitor Camera (VMC) may detect certain physical obstacles lower to the ground such as, the tires of an adjacent vehicle, parking lines, plants, etc. even though there are no obstacles behind the vehicle. Under this condition, the Smart Brake Support (SBS) system may determine that there is a possibility of a collision, notifying with a visual (screen display) and audible (warning sound), and the brakes possibly being applied in certain cases. Driver recognition result is not displayed (on equipped vehicles) The Driver Personalization system may not recognize the driver’s face to change the seat position settings that have been programmed. In this case the vehicle interprets the driver as a “guest” (non-personalized). The vehicle driver must be in the driver’s seat within 15 seconds of unlocking the vehicle to initiate the Driver Recognition function. Mazda Radar Cruise Control (MRCC) may reduce speed to match adjacent lane vehicle While driving on a curved road condition with the Mazda Radar Cruise Control (MRCC) activated, a vehicle in the right or left lane may be detected as a vehicle in front of the CX-90 and the MRCC will unexpectedly reduce vehicle speed to match the detected vehicle. The repair will be reprogramming the VCM with modified software via M-MDS, using MDARS. There are 28,404 vehicles in the campaign in the U.S. and U.S. Territories.

  Summary

  Some customers may experience a warning message for the approaching vehicle audible system (AVAS) right after the ignition is turned on (POWER ON) while a loud noise, such as a horn, occurs close to the vehicle. Upon inspection, DTC B1A03:2B [ISB_AMP] (AVAS device circuit malfunction) is stored in memory. (AVAS Malfunction, Pedestrians May Not Hear This Vehicle Approach, Drive Safely, Have the Vehicle Inspected) This may be caused by an internal initial diagnosis in the notification and warning amplifier detecting a false malfunction under this particular situation. To eliminate this concern, the control software of the notification and warning amplifier has been modified.

  Summary

  Some customers may feel a slight surge when driving at around 60 mph (100 km/h) in EV mode and decelerating with the accelerator pedal not fully released. If the accelerator pedal is fully released, the concern does not occur. This may be caused by improper torque control occurring for some shift down occasions. To eliminate this concern, the control software of the TCM has been modified.
