DTC C1A4A: Skid Control Buzzer Circuit [03/2014 - ]: Description

Based on pre-collision control, the driving support ECU provides warnings to the driver. The driving support ECU does this by sending a request signal to the skid control ECU to sound the skid control buzzer.

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

DTC No. DTC Detection Condition Trouble Area
C1A4A While the engine switch is on (IG), a skid control buzzer circuit malfunction signal is received from the skid control ECU for 1 second or more.
