Diagnostic Test

  1. CHECK FOR DELAMINATION ON THE WINDSHIELD 
    NOTE: If module has been reflashed or powered up while not connected to the windshield, this DTC will set. If this is the case, reattach the RSM to the windshield and proceed.
    1. Check the contact surface of the Rain Sensor Module to the windshield for delamination (this will resemble air bubbles in the contact area).

      Is delamination present on the windshield?

      Yes 

      No 

      • Go to step  2
  2. REPLACE THE RAIN SENSOR MODULE 
    1. With the scan tool read RSM DTCs.

      Does the scan tool read: B2211-RAIN SENSOR MODULE INITIALIZATION PERFORMANCE?

      Yes 

      No 

      • Test complete.
