DTC/CIRCUIT DIAGNOSIS

SOLAR CELL MODULE

Diagnosis Procedure

INFOID:0000000010119475

CHECK VEHICLE CONDITION

Visually check the appearance of the solar cell module for scratches, cracks, and dirt.

>> GO TO 2.

CHECK SOLAR CELL MODULE FUNCTION

1. Disconnect 12V battery negative terminal. Refer to

GI-29, "Precaution for Removing 12V Battery"

2. Move vehicle to an area (indoor acceptable) that the solar cell module can get sufficient sunlight.

3. Cover the solar cell module with a black cloth to shut out the sunlight.

4. Check voltage between 12V battery positive terminal and negative cable terminal.

5. Repeat covering and uncovering the solar cell module with black cloth, and check the voltage change.

NOTE:

If the voltage change is too small to judge, put a light source close or perform the operation outside where sun-

light is available.
Is the inspection result normal?

YES

>> GO TO 7.

Voltage does not change at 0 V.>>GO TO 3.

Voltage does not change at a constant voltage. >>There is a possibility of diffraction by other circuits. Repair

diffraction to start inspection.

CHECK HARNESS

1. Install 12V battery positive terminal and negative terminal.

2. Check voltage between coil and body ground.

Is the inspection result normal?

YES

>> GO TO 4.

>> Check the following items.

• 10 A fuse (#9)

• Harness or connector between 12V battery and coil for a break or short

CHECK COIL

Check voltage between coil and ground.

Is the inspection result normal?

YES

>> GO TO 5.

>> Replace coil.

< DTC/CIRCUIT DIAGNOSIS >

Check voltage between solar cell module and ground.

Is the inspection result normal?

YES

>> GO TO 6.

>> Repair harness or connector between coil and solar cell module.

CHECK HARNESS

Check continuity between solar cell module and ground.

Is the inspection result normal?

YES

>> Replace solar cell module.

>> Repair harness of connector.

CHECK DARK CURRENT

1. Install 12V battery positive terminal and negative terminal.

2. Check dark current. Refer to

CHG-9, "Work Procedure"

NOTE:

If the diode in solar cell module has a malfunction (poor commutation), dark current of 150 mA flows.
Is dark current normal?

YES

>> INSPECTION END

>> GO TO 8.

CHECK DARK CURRENT

Remove 10 A fuse (#9) to check dark current.
Is dark current normal?

YES

>> GO TO 9.

>> Excessive dark current in other circuit.

CHECK SOLAR CELL MODULE

1. Install 10 A fuse (#9).

2. Disconnect connector of solar cell module to check dark current.
Is dark current normal?

YES

>> Replace solar cell module.

>> Excessive dark current in other circuit.

DISCHARGED 12V BATTERY

SYMPTOM DIAGNOSIS

DISCHARGED 12V BATTERY

Description

INFOID:0000000010119476

DESCRIPTION

12V batteries go dead due to diverse factors, such as 12V battery deterioration, poor power generation in DC/

DC junction box, driving condition, malfunctioning wiring or control unit. In this case, it is important for the cor-

rect diagnosis to check vehicle condition, battery saver function condition, and operating state of the power

consumption control system (sleep function), in addition to an interview to the customer.

NOTE:

For battery saver function and the power consumption control system (sleep function), refer to the following

items:

• Exterior lamp battery saver system:

EXL-22, "EXTERIOR LAMP BATTERY SAVER SYSTEM : System

Description"

• Interior room lamp battery saver system:

INL-10, "INTERIOR ROOM LAMP BATTERY SAVER SYSTEM :

System Description"

• Power consumption control system (sleep function):

BCS-12, "POWER CONSUMPTION CONTROL SYS-

TEM : System Description"

For an interview, obtain detailed information about the following items as much as possible:

• History of 12V battery replacement by the customer

• Usual usage pattern

• Usage pattern immediately before the 12V battery goes dead or the situation at parking.

Diagnosis Procedure

INFOID:0000000010119477

CHECK INTERVIEW RESULT AND VEHICLE CONDITION

Check the use pattern of before and after the occurrence of malfunction and the vehicle condition of after the

occurrence of the malfunction. Refer to

CHG-12, "Description"

CAUTION:

To perform a field repair for a dead 12V battery, check the vehicle condition before restarting with a

booster cable and measure battery voltage, specific gravity of battery fluid, and dark current (with/

without the jumping battery connection) to perform a correct diagnosis.

>> GO TO 2.

CHECK 12V BATTERY

Check 12V battery. Refer to

PG-83, "Work Flow"
