7. Check for continuity between navigation unitconnector D (12P) terminal No. 1 and HFL-voice
control switch 5P connector terminal No. 2.
Go to step 8.
Repair open in the wire between the
navigation unit and the HFL-voice control switch, or
replace the cable reel.
8. Disconnect navigation unit connector A (24P). 9. Check for continuity between navigation unit
connector A (24P) terminal No. 5 and HFL-voice
control switch 5P connector terminal No. 4.
Replace the navigation unit (see page 23-355).
Repair open in the wire between navigation
unit and voice control switch, or replace the cable
reel.
10. Use the Mic Level dia gnostic under Functional
Setup (see page 23-309) to check the operation of
the microphone.
Check the operation of the voice control
system (see the Navigation System Manual).
Go to step 11.
11. Check the HFL DTCs (see page 23-360).
Repair the indicated DTCs.
Substitute a known-good HFL-navigation
microphone (see page 23- 358), then reconnect all
of the connectors and recheck. If the symptom/
indication goes away, replace the original
microphone. If the symptom/indication is still
present, replace the navigation unit (see page
23-355).
