AUTOHOLD WARNING BEEP
id041500107200
Purpose/Function
• Notifies the driver that the brake pedal is not depressed to prevent a mis-operation or accident.
Construction/Operation
• If there is a problem with the AUTOHOLD function and the electric parking brake while AUTOHOLD is operating without depressing brake pedal, the AUTOHOLD warning beep sounds.
• The AUTOHOLD warning beep is activated using the buzzer built into the instrument cluster.
• The instrument cluster receives (1) the AUTOHOLD warning beep request signal from the DSC HU/CM.
• The instrument cluster turns the transistor on (2) based on the AUTOHOLD warning beep request signal.
• When the transistor turns on, a ground circuit with the buzzer built into the instrument cluster is established and the warning beep sounds (3).
• When the driver operates the brake pedal and the brake fluid pressure is the specification or more, the AUTOHOLD warning beep stops.
