A. Test
(1) Do the Interface test of the IR (Ref. AMM TASK 34-14-00-740-001).
4. Fault Isolation
_______________
A. If during the test, with the ATT HDG selector switch at CAPT 3, the HDG data do not come into view on the VOR/ADF/DME RMI (21FN):
- do a check for a maintenance message in the BITE test of the IR system.
(1) If the BITE test gives a maintenance message:
- Do the trouble shooting procedure related to the maintenance message.
(2) If the BITE test does not give a maintenance message:
- replace the SEL SW-ATT HDG (13FP)
(a) If the fault continues:
- replace the RELAY-HDG SOURCE SEL (19FN). 1 If the fault continues:
_
- do a check of the wiring of the HDG SOURCE SEL relay (19FN): . pins A/A and A/Z to the ground points
