SECURITY AND LOCKS
NOTE:
Check the function settings of the body integrated unit if any of the following symptoms appear. <Ref. to
LAN(diag)-2, Basic Diagnostic Procedure.>
• The horn does not sound even when the security alarm is triggered and operating. As a cause, it is possi-
ble that the siren ON/OFF setting is set to ON in the customization function.
• The horn sounds when setting the security to ON (Monitoring condition) using the keyless transmitter. As
a cause, it is possible that the impact sensor present (ON) / not present (OFF) setting is set to ON in the cus-
tomization function though there is no impact sensor.
