 - N1 = 0

 - N2 = 0

 - FF = 0

 - EGT = ambient temperature

 4. Fault Isolation
_______________
 A. If the test is confirmed:
 (1) Do a check and repair the wiring between the FADEC GND PWR pushbutton switch (7KS1) and the EIU 1 (1KS1), (Ref. ASM 73-25/08).

 (2) If the fault continues:

 - replace the P/BSW-ENG/FADEC GND PWR/1 (7KS1).
 B. Do the functional test of the ECU (Ref. AMM TASK 73-21-60-720-040).
