U044F Invalid Data Received From Mirror Control Module B

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

U044F is stored when a controller receives data from mirror control module B that it cannot use; U014D is lost contact, U0514 covers module A. Depending on design, mirror modules adjust, fold and heat the exterior mirrors, store memory positions or run an interior mirror with camera display. Stellantis shows how the letters are assigned: case S2108000013 for the 2021 Jeep Grand Cherokee names module A as the combined rear view mirror module inside the cabin, whose lost-contact code U0213 sets in the BCM after a configuration restore wrongly enables a mirror that is not fitted. No manufacturer documents U044F publicly. FMVSS 111 sets the rear visibility rules such mirrors serve. Expect memory, folding, dimming or display functions handled by module B to stop working.

Likely causes

Vehicle configuration does not match the fitted mirror modules
Damaged wiring in the door hinge area or loose mirror connector
Internal fault of mirror control module B, often after water entry

Symptoms

  • Mirror adjustment, folding or memory function inoperative
  • Camera mirror display or automatic dimming unavailable
