id092200022200

Purpose

• The i-stop warning alarm alerts the driver that the driver-side door is open or the engine stalls while the engine is stopped by i-stop control.

Function

• When the instrument cluster receives the i-stop warning alarm request signal sent from the PCM via the CAN signal, the i-stop warning alarm sounds.

• The i-stop warning alarm sound pattern is as shown in the figure.

Construction

• The i-stop warning alarm sounds using the buzzer built into the instrument cluster.

Operation

1. The instrument cluster receives (1) the i-stop warning alarm request signal from the PCM.

2. The instrument cluster microcomputer turns the transistor on (2) based on the i-stop warning alarm request signal.

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