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.
CAUTION / NOTICE / HINT NOTICE: The lane departure alert system (w/ steering control) uses the CAN communication system. First, confirm that there are no malfunctions in the CAN communication system. Refer to How to Proceed with Troubleshooting. Click here PROCEDURE
