C1AA4 |
Yaw Rate Sensor Circuit |
|
DTC |
C1AA5 |
Yaw Rate Sensor Power Supply Voltage Circuit |
DESCRIPTION
The forward recognition camera receives vehicle stability signals from the yaw rate sensor (airbag ECU assembly). If the yaw rate sensor (airbag ECU assembly) 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 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 (airbag ECU assembly) indicating a malfunction in the yaw rate sensor is detected by the forward recognition camera for 5 seconds or more. |
Electronically controlled brake system |

Yaw Rate Sensor Power Supply Voltage Circuit |
2 seconds after the power switch is turned on (IG), a signal from the yaw rate sensor (airbag ECU assembly) indicating an abnormal yaw rate sensor power supply voltage signal is detected by the forward recognition camera for 5 seconds or more. |
Electronically controlled brake system |
CAUTION / NOTICE / HINT
NOTICE:
The front camera system uses the CAN communication system. First, confirm that there are no malfunctions in the CAN communication system. Refer to How to Proceed with Troubleshooting.
