(c) If the fault continues:

 - replace the VALVE-LP FUEL, ENG 2 (13QM) (Ref. AMM TASK 28-24-41-000-001) and (Ref. AMM TASK 28-24-41-400-001).

 (d) If the fault continues:

 - replace the CTL SW-ENG/MASTER 2 (2KC) on the panel 115VU.

 (2) If the valve is open:

 - replace the fuel pump and filter assembly (Ref. AMM TASK 73-11-10-000-003) and (Ref. AMM TASK 73-11-10-400-003).

 (3) If the fault continues, replace the HMU (Ref. AMM TASK 73-21-10-000-002) and (Ref. AMM TASK 73-21-10-400-002).

 C. Test
 (1) Start the engine 2 by the engine automatic start procedure (Ref. AMM TASK 71-00-00-710-003).

 (2) Make sure that there is no ECAM and CFDS fault message shown.

 B. If the fault symptom is identified by the CFDS message MASTER LEVER, HMU:
 NOTE : The fault is generated if there is a demand / position disagree on
____ the HMU HP fuel shut-off valve. While the A/C is electrically powered and the engine master lever is set to OFF.
 - disconnect the connector 4000KC-A from the HMU and make sure that, when the ENG/MASTER control switch on the 115VU is in the OFF position, there is 28VDC at pin AA/1 of the connector 4000KC-A (Ref. ASM 76-12/01) and (Ref. AWM 76-12-01).

 (1) If there is 28VDC:

 - replace the HMU (Ref. AMM TASK 73-21-10-000-002) and (Ref. AMM TASK 73-21-10-400-002).
 (2) If there is no 28VDC:
 - remove the panel 115VU.

 - do a check of the aircraft wiring between the connector 4000KC-A and the ENG/MASTER control switch (3KC) pin AA/1 to pin 1G.

 - do a check of the aircraft wiring between the ENG/MASTER control switch (3KC) pin 3G and the circuit breaker (1KC1) (Ref. ASM 76-12/01).

 (a) If the wiring is not correct:

 - repair the above defective wirings.

 (b) If the wiring is correct:

 - replace the CTL SW-ENG/MASTER 1 (3KC) on the panel 115VU. (Ref. R AWM 76-12-01)
 - install the panel 115VU and do a test program after removal/installation of a VU panel. (Ref. AMM TASK 31-10-00-700-001)
 C. Test
 (1) Start the engine 1 by the engine automatic start procedure (Ref. AMM TASK 71-00-00-710-003).

 (2) Make sure that there is no ECAM and CFDS fault message shown.
