Subtask 21-31-00-810-212-A
A. If one or both of the reports, LAST LEG REPORT, PREVIOUS LEG REPORT, and/or the test gives the maintenance message which follows,
Subtask 21-31-00-710-144-A - OUTFLOW VALVE ELEC 1 (68):
- replace the
VALVE-OUTFLOW (10HL), ELECTRONIC MODULE 1 (referred to as OFV (10HL)) AMM 21-31-51-000-002 and AMM 21-31-51-400-002.
NOTE: The electronic module 1 is connected to the electrical connector 10HL-A.
(1) If the fault continues:- replace the
VALVE-OUTFLOW (10HL), AUTO MOTOR 1 AMM 21-31-51-000-003 and AMM 21-31-51-400-003.
B. Do the test as given in the Para. 3.A.
