A. If the test gives the maintenance message:
- NO GPWS DATA
(1) Do the operational test of the Ground Proximity Warning System (Ref. AMM TASK 34-48-00-710-001).
(a) If the test gives a different maintenance message, you can find the related trouble shooting procedure in the applicable Page Block 101.
(2) If the fault continues:
- do a check and repair the wiring from the GPWC (1WZ) to the DMU (1TV) (Ref. ASM 31-37/01):
GPWC Connector AB/1C to DMU Connector AA/5C
