                        | Title: SUSPENSION CONTROL: ADAPTIVE VARIABLE SUSPENSION SYSTEM: C1783; Front Wheels Speed Sensor Signal Malfunction; 2019 - 2022 MY Avalon Avalon HV [04/2018 -        ] |  
                     
                        
                           | DTC | C1783 | Front Wheels Speed Sensor Signal Malfunction |  DESCRIPTIONThe speed sensors monitor the speed of the wheels and send an appropriate speed signal to the absorber control ECU through the skid control ECU (brake actuator assembly). If a malfunction occurs in either a front speed sensor or rear speed sensor, DTC C1783 is stored.
