"Requesting fault codes mode" will exit unless the fault code is acknowledged before it is repeated five
times. When all fault codes have been indicated, "clearing fault codes mode" will be entered. Refer to
.

Regarding Wiring Diagram information, refer to
INSPECTION FOR POWER SUPPLY AND GROUND CIRCUIT
1.
CHECK FUSES
Check for blown rear sonar system fuses.
Are any fuses blown?
YES
>> If fuse is blown, be sure to eliminate cause of malfunction before installing new fuse. Refer to
NO
>> GO TO 2.
2.
CHECK POWER SUPPLY CIRCUIT
1. Disconnect sonar control unit connector.
2. Turn ignition switch ON.
3. Check voltage between sonar control unit connector B24 termi-
nal 8 and ground.
Is there battery voltage?
YES
>> GO TO 3.
NO
>> Check harness for open between sonar control unit and
fuse.
3.
CHECK GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Check continuity between sonar control unit connector B24 ter-
minal 6 and ground.
Is there continuity?
YES
>> Inspection End.
NO
>> Check harness ground circuit.

SONAR SENSOR CIRCUIT INSPECTION
SONAR SENSOR CIRCUIT INSPECTION
Description
INFOID:0000000006159209
With power and ground supplied to the sonar sensors, the sonar sensors transmit an ultrasonic signal. This
signal is reflected back to the sensor by objects large enough and close enough to be detected. The sonar
sensors measure the time from the transmitted signal to the time the signal is reflected back and send this
information to the sonar control unit. Refer to
for more details.
Diagnosis Procedure
INFOID:0000000006159210
Regarding Wiring Diagram information, refer to
1.
CHECK REAR SONAR SENSOR CIRCUITS
1. Turn ignition switch OFF.
2. Disconnect sonar control unit connector and rear sonar sensor connectors.
3. Check continuity between sonar control unit harness connector
(A) and rear sonar sensor harness connectors (B).
4. Check continuity between sonar control unit harness connector
and ground.
Are the inspection results normal?
YES
>> Inspection End.
NO
>> Repair harness or connector.

SONAR BUZZER CIRCUIT INSPECTION
Description
INFOID:0000000006159211
When the A/T selector lever is not it park or neutral, a stationary object will be detected by the sonar sensors
causing the rear 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 very close to the vehicle, the tone will sound continuously.
Diagnosis Procedure
INFOID:0000000006159212
Regarding Wiring Diagram information, refer to
1.
CHECK REAR SONAR BUZZER
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Replace rear sonar buzzer. Refer to
SN-29, "Removal and Installation"
2.
CHECK REAR SONAR BUZZER CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect sonar control unit connector and rear sonar buzzer connector.
3. Check continuity between sonar control unit harness connector
(A) and rear sonar buzzer harness connector (B).
4. Check continuity between sonar control unit harness connector
and ground.
Are the inspection results normal?
YES
>> Inspection End.
NO
>> Repair harness or connector.
