## Discrepancy

DURING TAXI, NR 2 ENG EXPERIENCED AN UN-COMMANDED ENG SHUTDOWN. CREW OBSERVED THE ENG COMPUTER 2 CB (201E2) HAD TRIPPED. POWER LEVER WAS PUT IN CUT-OFF, A/C RETURNED TO RAMP. INSP OF NR 2 ENG INTAKE AND EXHAUST AREAS WAS NORMAL.  MAINT TROUBLESHOOTING REVEALED NR 2 DIGITAL ELECTRONIC ENGINE CONTROL (DEEC) TO BE DEFECTIVE. CB COULD NOT BE RESET; IN ADDITION THE DEFECTIVE DEEC CAUSED EMERGENCY BATTERY (93E2) CIRCUIT BREAKER TO OPEN. THE DEFECTIVE PART WAS REPLACED WITH A SERVICEABLE UNIT, CIRCUIT BREAKERS WERE RESET AND DEEC WAS ADJUSTED / TESTED IAW MFG SPECIFICATIONS AND AC WAS RETURNED TO SERVICE.  ABOVE MALFUNCTION SHOULD HAVE CAUSED ENG TO TRANSFER TO MANUAL MODE AND NOT CAUSED AN ENGINE SHUTDOWN.
