DESCRIPTION
While the alarm is armed, the EEPROM inside the main body ECU (multiplex network body ECU) will remember the armed state even if the battery is disconnected, and the alarm will sound when the battery is reconnected.
If the alarm does not sound when the battery is reconnected, the alarm may not have been set, or there may be a malfunction in the main body ECU (multiplex network body ECU).
