__________________
A. Test
(1) Do the BITE test of the weather radar 1 with the EIS DMC selector switch on the SWITCHING panel 8VU in CAPT/3 position (Ref. AMM TASK 34-41-00-740-002).
4. Fault Isolation
_______________
A. If the test result is satisfactory:
(1) Replace the DMC-1 (1WT1) (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001).
(2) If the fault continues:
- do a check of the wiring between DMC1 (1WT1) pins AA/12A, 12B and terminal block 1851VT39 pins A, F and between DMC1 (1WT1) pins AA/12C, 12D and terminal block 1851VT38 pins F, A (Ref. ASM 34-41/01).
B. If the test gives the maintenance message DMC1/2/3(1WT1/2/3)/WXR1(1SQ1):
(1) Replace the XCVR-WEATHER RADAR, 1 (1SQ1) (Ref. AMM TASK 34-41-33-000-004) and (Ref. AMM TASK 34-41-33-400-003).
(2) If the fault continues:
- do a check of the wiring between weather radar transceiver 1 (1SQ1) pins AB/2D, 3D and terminal block 1851VT39 pins D, J and between weather radar transceiver 1 (1SQ1) pins AB/2G, 3G and terminal block 1851VT38 pins J, D (Ref. ASM 34-41/01).
