B2630, B2631 SUNLOAD SENSOR

Description

INFOID:0000000004215322

COMPONENT DESCRIPTION

Sunload Sensor

The sunload sensor (1) is located on the driver’s side front defroster

grille. It detects sunload entering through windshield by means of a

photo diode. The sensor converts the sunload into a current value

which is then input into the auto amp.

Sunload Sensor Circuit

SUNLOAD INPUT PROCESS

The auto amp. also includes a processing circuit which averages the variations in detected sunload over a

period of time. This prevents drastic swings in the HAC system operation due to small or quick variations in

detected sunload.

For example, consider driving along a road bordered by an occasional group of large trees. The sunload

detected by the sunload sensor will vary whenever the trees obstruct the sunlight. The processing circuit aver-

ages the detected sunload over a period of time, so that the (insignificant) effect of the trees momentarily

obstructing the sunlight does not cause any change in the HAC system operation. On the other hand, shortly

after entering a long tunnel, the system will recognize the change in sunload, and the system will react accord-

ingly.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1. Turn ignition switch ON (READY) and wait at least 5 seconds.

2. Check DTC.

NOTE:

Perform DTC confirmation procedure under sunshine. When performing indoors, aim a light (more than

60 W) at sunload sensor, otherwise B2631 will indicate despite that sunload sensor is functioning properly.

3. Select “SELF-DIAG RESULTS” mode with CONDULT-III.

4. Touch “ERASE”, and recheck DTC.
Is DTC detected?

YES

>> Go to Diagnosis Procedure.

>> END.

Diagnosis Procedure

INFOID:0000000004215324

1.

CHECK VOLTAGE BETWEEN SUNLOAD SENSOR AND GROUND

2. Turn ignition switch ON.

3. Check voltage between sunload sensor harness connector M56 terminal 1 and ground.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> GO TO 4.

2.

CHECK CIRCUIT CONTINUITY BETWEEN SUNLOAD SENSOR AND AUTO AMP.

nector M37 terminal 26.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair harness or connector.

3.

CHECK SUNLOAD SENSOR

1. Reconnect sunload sensor connector and auto amp. connector.

2. Refer to 

HAC-45, "Component Inspection"

.

Is the inspection result normal?

YES

>> Replace auto amp. Refer to 

VTL-8, "Removal and Installation"

.

NO

>> Replace sunload sensor. Refer to 

VTL-10, "Removal and Installation"

.

4.

CHECK CIRCUIT CONTINUITY BETWEEN SUNLOAD SENSOR AND AUTO AMP.

1. Turn ignition switch OFF.

2. Disconnect auto amp. connector.

3. Check continuity between sunload sensor harness connector M56 terminal 1 and auto amp. harness con-

nector M37 terminal 7.
