Some 2012 ? 2013 model year Camry vehicles may exhibit a condition where ABS brake actuator pump motor noise is heard from the engine compartment with Brake, ABS and/or TRAC warning lamp(s) illuminated and Diagnostic Trouble Code (DTC) C1431 stored. This condition may be caused by a poor ground on the left fender side panel bracket after a collision repair. This may occur during body shop repairs or other repairs where the left side fender bracket grounds were left loose, not properly attached using the correct bolts, or improperly painted.
