Purpose
The tire pressure warning alarm warns the user that a tire pressure has decreased or notifies the user that the tire pressure warning alarm has been reset.
Function
If the instrument cluster receives a tire pressure warning alarm request signal sent from the DSC HU/CM via the CAN signal, the tire pressure warning alarm is sounded.
The tire pressure warning alarm sound pattern is as follows: For the conditions in which each alarm pattern sounds, refer to TIRE PRESSURE MONITORING SYSTEM (TPMS).

Tire pressure monitoring system initialization

Construction
The tire pressure warning alarm sounds using the buzzer built into the instrument cluster.
Operation
1. The instrument cluster receives (1) the tire pressure warning alarm request signal from the DSC HU/CM.
2. The instrument cluster microcomputer turns the transistor on (2) based on the tire pressure warning alarm request signal.
3. When the transistor turns on, the ground circuit of the alarm is established and the alarm sounds (3).
