(a) If the fault continues:
- do a check and repair the wiring of the TERRAIN POP-UP CAPT discrete between the GPWC (1WZ) and the TERR ON ND, CAPT pushbutton switch (30WZ1): for pin AA/1A of the GPWC (Ref. ASM 34-48/02).
B. Do the test given in Para. 3.

A. Test
(1) Do the BITE test of the Enhanced GPWS (Ref. AMM TASK 34-48-00-740-002).
4. Fault Isolation
_______________
A. If the BITE test gives the maintenance message: FO TERR ON ND PB SW (30WZ2)/GPWC (1WZ) - on the LDG GEAR CTL & IND PNL (402VU), make sure that the TERR ON ND,
F/O pushbutton switch (30WZ2) is not pushed (the ON legend is off)
- do a check for ground at pin AA/1B of the GPWC (Ref. ASM 34-48/02).
(1) If there is no ground:
- replace the GPWC (1WZ) (Ref. AMM TASK 34-48-34-000-001) and (Ref. AMM TASK 34-48-34-400-001).
