Used for the power generation voltage variable control system.
Refer to
Combination meter (Charge warning lamp)
The IC 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.
IPDM E/R
Used for the power generation voltage variable control system.

INFOID:0000000000964268
System Description
INFOID:0000000000964269
By performing the power generation voltage variable control, the engine load due to the power generation of
the alternator is reduced and fuel consumption is decreased.
NOTE:
When any malfunction is detected in the power generation voltage variable control system, the power genera-
tion is performed according to the characteristic of the IC regulator of the alternator.

Component part
Description
Battery current sensor
Battery 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.
ECM
Battery 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/R
IPDM E/R converts the received power generation command val-
ue into the power generation command signal (PWM signal) and
sends it to the IC regulator.
Alternator (IC regulator)
IC regulator controls the power generation voltage by the target
power generation voltage based on the received power generation
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 regulator.

B TERMINAL CIRCUIT
COMPONENT DIAGNOSIS
B TERMINAL CIRCUIT
Description
INFOID:0000000000964272
“B” terminal circuit supplies power to charge the battery and operate the vehicle’s electrical system.
Diagnosis Procedure
INFOID:0000000000964273
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
.
NO
>> Check harness between battery and alternator for poor continuity.
