Check that the security alarm works. If the alarm does not work, carry out troubleshooting. (Refer to GROUP 54D, Troubleshooting or GROUP 54E, Troubleshooting ).
note
The adjustment function allows you to change the security alarm setting from "without function (initial setting)" to "alarm by horns and hazard warning lamps" or "alarm by hazard warning lamps only". Prior to that check, confirm which setting is activated.
