U0571 Invalid Data Received From Image Processing Sensor L

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

U0571 closes the image-processing-sensor block; the next number, U0572, already belongs to a vehicle motion control module. An image processing sensor computes objects inside the camera itself, for instance with a system-on-chip as in Bosch's multi purpose camera or with Mobileye's EyeQ processors, the first generation of which launched in 2008. That differs from an image processing module (U053B–U053D), a separate controller that evaluates camera streams. U0571 means sensor L's results arrived but failed the receiver's checks. No manufacturer documents U0571 or partner U0270, and the position of L is unknown. Expect the dependent assistant to switch off; no MIL.

Likely causes

Processing software in sensor L faulty or not matching the receiver
Wiring or connector fault corrupting the sensor's messages
Image processing sensor L internally faulty

Symptoms

  • Assistance function using sensor L unavailable
  • Code stored without warning lamp

Repair estimate
