WARNING: This page is about a different car, the 2021 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
- The connectivity master unit (CMU) determines the presence/non-presence of the commander switch based on the communication condition between the commander switch and records it when the ignition is switched to ACC or ON (engine off or on) the first time after connecting the negative battery terminal.
- If the commander switch is installed with the negative battery terminal connected and the CMU recorded that there is no commander switch, the commander switch does not operate.
- For the commander switch installation/removal, always disconnect the negative battery terminal, switch the ignition to ACC or ON (engine off or on) after the servicing is completed so that the CMU records the presence/non-presence of the commander switch.
- Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION (US) .)
