NOTE: Check the vehicle battery condition first.
Check the connectors for poor connections or loose terminals.
1. Verify the SVC mode setting in the navigation unit sound set-up.
Change the setting to Mid and retest
(see page 23-164).
Go to step 2.
2. Do the self-diagnostic function for the vehicle speed pulse indication (see page 23-190).
Substitute a known-good navigation unit
(see page 23-355), and retest. If the symptom/
indication goes away, replace the original
navigation unit.
Go to step 3.
3. Test-drive the vehicle at highway speeds, and monitor if the volume increases.
Intermittent failure, the system is OK at this
time.
Go to step 4. 4. Remove the navigation unit (see page 23-355) and
disconnect navigation unit connector A (24P).
NOTE: Eject all the discs before removing the navigation unit to prevent damaging the CD player’s load
mechanism.
Remove the PC card before removing the navigation unit.
5. Drive the vehicle, and have an assistant measure voltage at navigation unit connector A (24P)
terminal No. 15.
Replace the navigation unit (see page 23-355).
Repair open or shorts in the wire between
navigation unit connector A (24P) terminal No. 15
and ECM/PCM connector A (44P) terminal No. 29. If
no opens or shorts are found, Update the ECM/
PCM (see page 11-227) if it does not have the latest
software or substitute a known-good ECM/PCM
(see page 11-228).
