3. Fault Confirmation
__________________
A. Test
(1) Make sure that the engine 2 shutdown time was of 5 minutes minimum.
(2) Do the operational test of the Engine Interface Unit (Ref. AMM TASK 73-25-34-710-043).
4. Fault Isolation
_______________
A. If the test gives the maintenance message 115VU (MASTER LEVER 2SW):
- do a check and repair the wiring between the ENG/MASTER CTL switch (2KC) and the EIU 2 (1KS2), (Ref. ASM 73-25/08).
(1) If the fault continues:
(a) Replace the CTL SW - ENG/MASTER 2 (2KS).
(b) Do the operational test of the Engine Interface Unit (Ref. AMM TASK 73-25-34-710-040).
