SUBJECT: ORDERING REQUIREMENT FOR AT COMPONENTS FOR H3T (INLINE 6) Use this guide before ordering or replacing an AT component on applicable H3T vehicles. QUICK CHECKLIST BEFORE ORDERING • Confirm the vehicle is a CX-90 (KK) or CX-70 (KJ) with H3T and is within the applicable market coverage. • In GEPC, identify the AT component part number for the vehicle. • Use the GEPC lookup tables below to determine whether the vehicle requires Table A or Table B parts. • Order the complete set of parts listed in the applicable table. DO NOT order the AT component by itself. • Check whether water hose removal is required for that GEPC part number. • Follow the applicable WSM repair procedure for AT component removal/installation, water hose removal, and oil hose/oil pipe installation in MGSS. IMPORTANT: If only the AT component is ordered, required replacement parts will be missing, and the repair cannot be completed.

The new/superseded design can be used in place of the old/original design as the coolant hose (D-Code 21-5LX) is no longer needed to be used. Transmission part numbers beginning with supersession level “A” have had this change.

SA-036-242024-06-04. Other. STRUCTURE:BODY. 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.
SA-035-242024-06-04. Other. ENGINE. There is a concern that some water pumps are being replaced that are not faulty, due to signs of a very small coolant leak from the bleed hole.
