B TERMINAL CIRCUIT

Description

INFOID:0000000005146559

The terminal “1” circuit supplies power to charge the battery and operate the vehicles electrical system.

Diagnosis Procedure

INFOID:0000000005146560

Regarding Wiring Diagram information, refer to 

CHG-14, "Wiring Diagram"

.

1.

CHECK TERMINAL “1” CONNECTION

1. Turn ignition switch OFF.

2. Verify terminal “1” is clean and tight.
Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair terminal “1” connection. Confirm repair by performing complete Starting/Charging system

test. Refer to diagnostic station instruction manual.

2.

CHECK TERMINAL “1” CIRCUIT

Check voltage between generator connector E204 terminal 1 and

ground.

Is voltage reading as specified?

YES

>> GO TO 3.

NO

>> Check harness for open between generator and fusible

link.

3.

CHECK TERMINAL “1” CONNECTION (VOLTAGE DROP TEST)

1. Start engine, then engine running at idle and warm.

2. Check voltage between battery positive terminal and generator

connector E204 terminal 1.

Is the voltage reading as specified?

YES

>> Terminal “1” circuit is normal. Refer to 

CHG-5, "Work

Flow"

.

NO

>> Check harness between battery and generator for high resistance.

L TERMINAL CIRCUIT

L TERMINAL CIRCUIT

Description

INFOID:0000000005146561

The terminal “2” (L) circuit controls the charge warning lamp. The charge warning lamp illuminates when the

ignition switch is set to ON or START. When the generator is providing sufficient voltage with the engine run-

ning, the charge warning lamp will go off. If the charge warning lamp illuminates with the engine running, a

malfunction is indicated.

Diagnosis Procedure

INFOID:0000000005146562

Regarding Wiring Diagram information, refer to 

CHG-14, "Wiring Diagram"

.

1.

CHECK CHARGE WARNING LAMP CIRCUIT CONNECTION

Verify generator connector E205 terminal 2 is clean and tight. 
Is the connection secure?

YES

>> GO TO 2.

NO

>> Repair the connection. Confirm repair by performing complete Starting/Charging system test.

Refer to diagnostic station instruction manual.

2.

CHECK CHARGE WARNING LAMP CIRCUIT

1. Disconnect generator connector E205.

2. Apply ground to generator harness connector E205 terminal 2

with the ignition switch in the ON position.

Does the charge lamp illuminate?

YES

>> Check generator function. Refer to 

CHG-5, "Work Flow"

.

NO

>> GO TO 3.

3.

CHECK HARNESS CONTINUITY

1. Turn ignition switch OFF.

2. Disconnect the generator connector E205 and combination

meter connector M24.

3. Check continuity between generator harness connector E205

(A) terminal 2 and combination meter harness connector M24

(B) terminal 6.

4. Check continuity between generator harness connector E205

(A) terminal 2 and ground.

Are the continuity results as specified?

YES

>> Replace the combination meter. Refer to  

MWI-100, "Removal and Installation"

.

NO

>> Repair the harness or connector.

Charge lamp should illuminate

Description

INFOID:0000000005146563

The output voltage of the generator is controlled by the IC regulator at terminal “3” (S) detecting the input volt-

age. Terminal “3” circuit detects the battery voltage to adjust the generator output voltage with the IC regulator.

Diagnosis Procedure

INFOID:0000000005146564

Regarding Wiring Diagram information, refer to 

CHG-14, "Wiring Diagram"

.

1.

CHECK VOLTAGE REGULATOR CIRCUIT CONNECTION

Check to see if connector E205 terminal 3 is clean and tight. 
Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair terminal connection. Confirm repair by performing complete Starting/Charging system test.

Refer to diagnostic station instruction manual.

2.

CHECK VOLTAGE REGULATOR CIRCUIT

Check voltage between generator harness connector E205 terminal

3 and ground.

Does battery voltage exist?

YES

>> Refer to 

CHG-5, "Work Flow"

.

NO

>> Check harness for open between generator and fuse.
