SN-8

< SYSTEM DESCRIPTION >

REAR SONAR SYSTEM

"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

SN-16, "DTC Index"

.

CLEARING FAULT CODES MODE

NOTE:

While in "clearing fault codes mode", self-diagnosis will automatically exit if no activity occurs for 30 seconds.
1. Push and hold sonar system OFF switch for three seconds to

reset time-out counter.

2. Push and hold sonar system OFF switch for three seconds to

clear codes.

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 

GI-

42, "Circuit Inspection"

.

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 

SN-5, "System Description"

 for more details.

Diagnosis Procedure

INFOID:0000000006159210

Regarding Wiring Diagram information, refer to 

SN-17, "Wiring Diagram"

.

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 

SN-17, "Wiring Diagram"

.

1.

CHECK REAR SONAR BUZZER

Refer to 

SN-11, "Component Inspection"

.

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.
