Toyota Sienna Service Manual: Security Indicator Light Circuit
DESCRIPTION
Even when the theft deterrent system is in the disarmed state, the security indicator blinks due to a signal output from the immobiliser system. The security indicator blinks continuously due to a continuous signal received from the immobiliser system while in the armed state.
The multiplex network body ECU causes the security indicator to light up or blink only during the arming preparation state and alarm sounding states.
