                        | Title: CRUISE CONTROL: LANE DEPARTURE ALERT SYSTEM (w/ Steering Control) (for HV Model): C1AA2; Vehicle Speed Tolerance Malfunction; 2019 - 2021 MY Avalon HV [04/2018 - 08/2021] |  
                     
                        
                           | DTC | C1AA2 | Vehicle Speed Tolerance Malfunction |  DESCRIPTIONThe forward recognition camera receives vehicle speed tolerance signals from the combination meter assembly. If the combination meter assembly detects a vehicle speed tolerance malfunction signal, it informs the forward recognition camera via CAN communication, and DTC C1AA2 is stored.
