Purpose
The keyless warning alarm notifies the driver that the remote transmitter cannot be verified or the steering lock cannot be released.
Function
When the instrument cluster receives the keyless warning alarm request signal sent from the start stop unit via the CAN signal, the keyless warning alarm sounds.
The keyless warning alarm sound pattern is as shown in the figure. For the conditions that the alarm for each pattern sounds, refer to KEYLESS ENTRY SYSTEM (without advanced keyless entry system)/ADVANCED KEYLESS ENTRY SYSTEM (with advanced keyless entry system).
Pattern A

Pattern B

Pattern C

Construction
The keyless warning alarm sounds using the buzzer built into the instrument cluster.
Operation
1. The instrument cluster receives (1) the keyless warning alarm request signal from the start stop unit.
2. The instrument cluster microcomputer turns the transistor on (2) based on the keyless warning alarm request signal.
3. When the transistor turns on, the ground circuit of the alarm is established and the alarm sounds (3).
