DTC Table
WARNING: This page is about a different car, the 2020 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
- If there is any vehicle malfunction complaint lodged by a customer, refer to "FOREWORD" and perform CAN malfunction diagnosis following the steps in the troubleshooting procedure.
(See FOREWORD .)
NOTE:
- DTC is a capital "U". The DTCs which are not described in the following table can be verified by the "Reference for initial letter of DTC is capital U".
