L TERMINAL CIRCUIT (OPEN)

Description

INFOID:0000000005514986

The “L” terminal circuit controls the charge warning lamp. The charge warning lamp illuminates when the igni-
tion switch is set to ON or START. When the alternator is providing sufficient voltage with the engine running,
the charge warning lamp will go off. If the charge warning lamp illuminates with the engine running, a malfunc-
tion is indicated.

Diagnosis Procedure

INFOID:0000000005514987

1.

CHECK “L” TERMINAL CONNECTION

1.

Turn ignition switch OFF.

2.

Check if “L” terminal is clean and tight.

Is the inspection result normal?

YES

>> GO TO 2.

NO

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

test. Refer to Technical Service Bulletin.

2.

CHECK “L” TERMINAL CIRCUIT (OPEN)

1.

Disconnect alternator connector.

2.

Apply ground to alternator harness connector terminal.

3.

Check condition of the charge warning lamp with the ignition switch in the ON position.

Does it illuminate?

YES

>> “L” terminal circuit is normal. Refer to 

CHG-3, "Work Flow"

.

NO

>> GO TO 3.

3.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1.

Disconnect the battery cable from the negative terminal.

2.

Disconnect the combination meter connector.

3.

Check continuity between alternator harness connector and combination meter harness connector.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair the harness or connector.

4.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

Check continuity between combination meter harness connector and fuse block.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Repair the harness.

5.

CHECK POWER SUPPLY CIRCUIT

Description

INFOID:0000000005514988

The “L” terminal circuit controls the charge warning lamp. The charge warning lamp illuminates when the igni-
tion switch is set to ON or START. When the alternator is providing sufficient voltage with the engine running,
the charge warning lamp will go off. If the charge warning lamp illuminates with the engine running, a malfunc-
tion is indicated.

Diagnosis Procedure

INFOID:0000000005514989

1.

CHECK “L” TERMINAL CIRCUIT (SHORT)

1.

Turn ignition switch OFF.

2.

Disconnect alternator connector.

3.

Turn ignition switch ON.

Does charge warning lamp illuminate?

YES

>> GO TO 2.

NO

>> Refer to 

CHG-3, "Work Flow"

.

2.

CHECK HARNESS CONTINUITY (SHORT CIRCUIT)

1.

Turn the ignition switch OFF.

2.

Disconnect the battery cable from the negative terminal.

3.

Disconnect combination meter connector.

4.

Check continuity between combination meter harness connector and ground.

Is the inspection result normal?

YES

>> Replace combination meter.

NO

>> Repair the harness.

S TERMINAL CIRCUIT

S TERMINAL CIRCUIT

Description

INFOID:0000000005514990

The output voltage of the alternator is controlled by the IC voltage regulator at the “S” terminal detecting the
input voltage.
The “S” terminal circuit detects the battery voltage to adjust the alternator output voltage with the IC voltage
regulator.

Diagnosis Procedure

INFOID:0000000005514991

1.

CHECK “S” TERMINAL CONNECTION

1.

Turn ignition switch OFF.

2.

Check if “S” terminal is clean and tight.

Is the inspection result normal?

YES

>> GO TO 2.

NO

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

test. Refer to Technical Service Bulletin.

2.

CHECK “S” TERMINAL CIRCUIT

Check voltage between alternator harness connector and ground.

Is the inspection result normal?

YES

>> Refer to 

CHG-3, "Work Flow"

.

NO

>> Check harness for open between alternator and fuse.
