CHARGING SYSTEM
Component part Description
AlternatorThe alternator provides DC voltage to operate the vehicle's electri-
cal system and to keep the battery charged.
Combination meter (Charge warning lamp)The IC voltage regulator warning function activates to illuminate
the charge warning lamp, if any of the following symptoms occur
while alternator is operating:
 Excessive voltage is produced.
 No voltage is produced.

< FUNCTION DIAGNOSIS >
POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM
Component Description
INFOID:0000000003860520
Component part Description
Battery current sensorBattery current sensor is installed to the battery cable at the neg-
ative terminal, and it detects the charging/discharging current of
the battery and sends the voltage signal to ECM according to the
current value.
ECMBattery current sensor detects the charging/discharging current of
the battery. ECM judges the battery condition based on this signal.
ECM judges whether to perform the power generation voltage
variable control according to the battery condition.
When performing the power generation voltage variable control,
ECM calculates the target power generation voltage according to
the battery condition and sends the calculated value as the power
generation command value to IPDM E/R.
IPDM E/RIPDM E/R converts the received power generation command val-
ue into the power generation command signal (PWM signal) and
sends it to the IC voltage regulator.
Alternator (IC voltage regulator)IC voltage regulator controls the power generation voltage by the
target power generation voltage based on the received power gen-
eration command signal.
When there is no power generation command signal, the alterna-
tor performs the normal power generation according to the char-
acteristic of the IC voltage regulator.

B TERMINAL CIRCUIT
DescriptionINFOID:0000000003860521
“B” terminal circuit supplies power to charge the battery and to operate the vehicle’s electrical system.
Diagnosis ProcedureINFOID:0000000003860522
1.CHECK “B” TERMINAL CONNECTION
1. Turn ignition switch OFF.
2. Check if “B” terminal is clean and tight.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair “B” terminal connection. Confirm repair by performing complete Starting/Charging system
test. Refer to Technical Service Bulletin.
2.CHECK “B” TERMINAL CIRCUIT
Check voltage between alternator “B” terminal and ground.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Check harness for open between alternator and fusible link.
3.CHECK “B” TERMINAL CONNECTION (VOLTAGE DROP TEST)
1. Start engine, then engine running at idle and warm.
2. Check voltage between battery positive terminal and alternator “B” terminal.
Is the inspection result normal?
YES >> “B” terminal circuit is normal. Refer to CHG-2, "Work Flow".
NO >> Check harness between battery and alternator for poor continuity.

L TERMINAL CIRCUIT (OPEN)
L TERMINAL CIRCUIT (OPEN)
DescriptionINFOID:0000000003860523
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 ProcedureINFOID:0000000003860524
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-2, "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
1. Connect the battery cable to the negative terminal.
