_______________
A. If the test is confirmed:
(1) Do a check and repair the wiring between the FADEC GND PWR pushbutton switch (7KS2) and the EIU 2 (1KS2), (Ref. ASM 73-25/08).
(2) If the fault continues:
- replace the P/BSW-ENG/FADEC GND PWR/ 2 (7KS2).
B. Do the functional test of the ECU (Ref. AMM TASK 73-21-60-720-040).
