Dynamic Radar Cruise Control System

DTC P1575 WARNING BUZZER MALFUNCTION

CIRCUIT DESCRIPTION

DTC Detection Condition:

The ABS & traction actuator assembly (skid control ECU) receives the alarm demand signal from the ECM and operates the skid control buzzer.

The buzzer sounds to warn that the distance between the vehicle in front and your own vehicle is shortening.

HINT: If the vehicle ahead in the same lane significantly decreases its speed or another vehicle pulls in front of your own vehicle, adequate deceleration cannot be applied and the vehicle-to-vehicle distance will shorten. At this time, the system sounds the buzzer and the master warning light blinks to inform the driver.

This circuit uses CAN for communication. Therefore, if there are any malfunctions in the communication circuit, one or more DTCs in the CAN communication system is/are output.
