Ye s > > G O T O 2 .
No >> Check combination meter trouble diagnosis. Refer toDI-28, "
Vehicle Speed Signal Inspection
[With ESP]" in “COMBINATION METERS”.
2. VEHICLE SPEED SIGNAL CHECK
1. Start engine and drive vehicle at more than 40 km/h (25MPH).
2. Check the signal between audio unit harness connector M41
terminal 22 (L/W) and ground with CONSULT-II or oscilloscope.
OK or NG
OK >> Replace audio unit.
NG >> GO TO 3.
3. HARNESS CHECK
1. Turn the ignition switch OFF.
2. Disconnect audio unit connector and combination meter con-
nector.
3. Check continuity between audio unit harness connector M41 ter-
minal 22 (L/W) and Unified meter control unit harness connector
M44 terminal 33 (L/W).
4. Check continuity between audio unit harness connector M42 ter-
minal 22 (L/W) and ground.
OK or NG
OK >> Check combination meter system. Refer to DI-22, "Diagnosis Flow" in “COMBINATION
METERS”.

NAVI control unit controls images on the display.
NAVI SWITCH
NAVI switch connects to the display and transfer unit with com-
munication lines. NAVI switch transmits the demand signal and
the response signal with the serial transmission.
Communication form of the operation signal is conversed in
transfer unit to NAVI switch. The operation signal is transmitted
to NAVI control unit.

SELF–DIAGNOSIS RESULT
Quick reference table
1. Select an applicable diagnosis No. in the diagnosis result quick reference table.
2. Find estimated malfunctioning system in the diagnosis No. table and perform check.
3. Turn the ignition switch to OFF and perform self-diagnosis again.

Method of diagnosis for malfunctioning system
When system does not start, indicate malfunction connection between units by outbreak sound from sys-
tem.
Diagnosis procedure
1. Turn ignition switch ON. Make sure whether or not route guide start sound which is output from NAVI con-
trol unit indicate 10 seconds after.
2. Push and hold “MAP” and “ ” switches simultaneously for 5 seconds or more. Make sure whether or not
2 times of beep sound or route guide start sound indicate.
3. According to the former two steps, Select an proper diagnosis No. in the diagnosis result quick reference
table.
4. Find estimated malfunctioning system from the diagnosis No. table and perform check.
