id0212002028f3


Purpose

•  The tire pressure monitoring system warning alarm warns the user that a tire pressure has decreased.

Function

•  If the instrument cluster receives a tire pressure monitoring alarm request signal sent from the start stop unit via the CAN signal, the tire pressure monitoring alarm is sounded.
•  The tire pressure monitoring system warning alarm sound pattern is as shown in the figure:

Construction

•  The tire pressure monitoring system warning alarm sounds using the buzzer built into the instrument cluster.

Operation

1.  The instrument cluster receives (1) the tire pressure monitoring system warning alarm request signal from the start stop unit.

2.  The instrument cluster microcomputer turns the transistor on (2) based on the tire pressure monitoring system warning alarm request signal.

3.  When the transistor turns on, the ground circuit of the alarm is established and the alarm sounds (3).
