• The connectivity master unit (CMU) determines the presence/non-presence of a commander switch and records it based on the communication status when the ignition is switched ON (engine off or on) or to the ACC position for the first time after the negative battery terminal is connected.
• If the negative battery terminal is connected while the CMU has recorded the non-presence of the commander switch and thereafter a commander switch is installed, the installed commander switch will not operate.
• When installing or removing the commander switch, always disconnect the negative battery terminal, and after the servicing is completed, switch the ignition to ACC or ON (engine off or on) to allow the CMU to record the presence/non-presence of the commander switch.
