## Discrepancy

AIRCRAFT WAS GROUNDED: FAULT MESSAGE FOR LEFT 2/ EMERGENCY POWER SUPPLY UNIT DISPLAYED DURING SYSTEM TEST. MAINTENANCE FOUND THE L1 (AALA202601127620) AND R1 (AALA202601128700) DOOR SLIDES CAUSING THE MESSAGE AND REPLACED BOTH OF THEM PER TASK CARD 26L00025011. A SATISFACTORY OPERATIONAL CHECK OF THE EMERGENCY LIGHTING WAS ACCOMPLISHED WITH NO MESSAGES NOTED.
