DESCRIPTION

The forward recognition camera receives vehicle stability signals from the acceleration sensor (yaw rate sensor). If the acceleration sensor (yaw rate sensor) detects an abnormal yaw rate sensor signal or yaw rate sensor power supply voltage, it informs the forward recognition camera via CAN communication, and DTC C1AA4 or C1AA5 is stored.

DTC No. Detection Item DTC Detection Condition Trouble Area
C1AA4 Yaw Rate Sensor Circuit 2 seconds after the power switch is turned on (IG), a signal from the yaw rate sensor indicating a malfunction in the yaw rate sensor is detected by the forward recognition camera for 5 seconds or more. Electronically controlled brake system
C1AA5 Yaw Rate Sensor Power Supply Voltage Circuit 2 seconds after the power switch is turned on (IG), a signal from the yaw rate sensor indicating an abnormal yaw rate sensor power supply voltage signal is detected by the forward recognition camera for 5 seconds or more.
