DTC C1A4A: Skid Control Buzzer Circuit [12/2015 - 11/2017]: Description

Based on pre-collision control, the driving support ECU communicates to the driver to be careful. The driving support ECU performs this by sending a sounding signal to the skid control ECU to sound the skid control buzzer.

When the skid control ECU detects a malfunction in the VSC warning buzzer circuit, a malfunction signal is sent to the driving support ECU, and a DTC is stored. Although the skid control ECU sends a malfunction signal to the driving support ECU, the vehicle stability control system does not stored a relevant malfunction detection DTC.
