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