Revision: November 2009 2006 QX56
If an error occurred before the ignition switch was turned to ON and does not occur again until the “Self-diag-
nosis ” is completed, the diagnosis result will be judged normal. Therefore, those errors in the past which can-
not be found by the “Self-diagnosis” must be found by diagnosing the “Error History”.
The Error History displays the time and place of the most recent occurrence of that error. However, take note
of the following points.

Correct time of the error occurrence may not be displayed when the GPS antenna substrate within the
NAVI control unit has malfunctioned.

Place of the error occurrence is represented by the position of the current-location mark at the time when
the error occurred. If the current-location mark has deviated from the correct position, then the place of
the error occurrence may be located correctly.

The maximum number of occurrences which can be stored is 50. For the 51st and later occurrences, the
displayed number remains 50.
When a reproducible malfunction occurred but its cause cannot be identified because several errors are
present, record the item, number and place (longitude/latitude) of error occurrence (or delete the Error His-
tory), then turn the ignition switch from OFF to ON to reproduce the malfunction. Check the Error History to
find the items which show an increased number of occurrences, and diagnose the item.

FUNCTION
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No. 12 , located in the fuse block (J/B)]

to sonar control unit terminal 8, and

through 10A fuse (No. 51, located in the IPDM E/R)

to back-up lamp relay terminals 1 and 3.
Ground is supplied

to sonar control unit terminal 6

through body grounds B7 and B19.
With the ignition switch in the ON or START position, and the transmission gear selector lever in the R posi-
tion, power is supplied

to sonar control unit terminal 5

from back-up lamp relay terminal 5.
With power and ground supplied, transmission gear selector lever in R position, and the rear sonar system
OFF switch ON, the rear sonar system will detect obstacles within 1.8 m (5.9 ft.) of the rear sonar sensors.
The vehicle operator is notified of obstacles by varied rate of tone from the sonar buzzer depending on dis-
tance of obstacle being sensed.
REAR SONAR SYSTEM OFF SWITCH
With power and ground supplied to the sonar control unit, transmission gear selector lever in R position, the
sonar system can be disabled and the sonar buzzer silenced by momentarily pressing the rear sonar system
OFF switch. The rear sonar system OFF indicator lamp will be illuminated in the rear sonar system OFF
switch.
To disable the rear sonar system, ground is supplied

to sonar control unit terminal 13

through rear sonar system OFF switch terminal 1

through rear sonar system OFF switch terminal 2

from body grounds M57, M61, and M79.
To light the rear sonar system OFF indicator, power is supplied

from sonar control unit terminal 4

to the rear sonar system OFF switch terminal 5.
Ground is supplied

to the rear sonar system OFF switch terminal 6

from body grounds M57, M61, and M79.
The rear sonar system and buzzer will be disabled and the rear sonar system OFF indicator will be illuminated
until the ignition switch is turned OFF. When the ignition switch is turned ON, the rear sonar system will be
enabled. Depressing the rear sonar system OFF switch momentarily will enable the rear sonar system also.
Enabling the rear sonar system will cause the rear sonar system OFF indicator to go out.
SONAR BUZZER
With power supplied to the sonar control unit and the transmission gear selector lever in R position, a station-
ary object that is at least 7.0 cm (2.8 in.) wide and 1.0 m (39.0 in.) tall and that is closer than 1.8 meters (5.9 ft.)
will be detected by the rear sonar sensors, causing the sonar buzzer to sound a tone. As the vehicle moves
closer to the object, the rate of the tone will increase. When the object is less than 25.0 cm (10 in.) from the
rear bumper, the tone will sound continuously.
Power is supplied

to sonar buzzer terminal 1

from sonar control unit terminal 7.
Ground is supplied

to sonar buzzer terminal 2

from sonar control unit terminal 3.
