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
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.

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
.
NO
>> Check harness for open between alternator and fuse.
