Combination meter (c
harge warning lamp) The IC regulator warning function activates to illuminate the
charge warning lamp if any of the following symptoms occur while
generator is operating:
• Excessive voltage is produced.
• No voltage is produced.
Battery current sensor The battery current sensor is located on the battery cable terminal.
The battery current sensor detects the charging/discharging cur-
rent of the battery and sends a voltage signal to the ECM accord-
ing to the current value detected.

CHARGING SYSTEM DIAGNOSIS WITH EXP-800 NI OR GR8-1200 NI
To test the charging system, use t he following special service tools:
• EXP-800 NI Battery and electrical diagnostic analyzer
• GR8-1200 NI Multitasking battery and electrical diagnostic station
NOTE:
Refer to the applicable Instruction Manual fo r proper charging system diagnosis procedures.

2.STOP POWER GENERATION VOLT
AGE VARIABLE CONTROL SYSTEM
Stop the operation of the power generation voltage variabl e control in either of the following procedures.
• After selecting “ENGINE” using CONSULT, set the DUTY value of “ALTERNATOR DUTY” to 0 % by select- ing “ALTERNATOR DUTY” of “Active Test”. Continue “Active Test” until the end of inspection. (When the
DUTY value is 0 or 100 %, the normal power generation is performed according to the characteristic of the
IC regulator of the generator.)
• Turn the ignition switch OFF, and disconnect the batte ry current sensor connector. [However, DTC (P1550–
P1554) of the engine might remain. After finishing the inspection, connect the battery current sensor connec-
tor and erase the self diagnosis results history of the engine using CONSULT.]
>> GO TO 3.
3.DIAGNOSIS WITH EXP-800 NI OR GR8-1200 NI
Perform the charging system test using Multitasking battery and electrical diagnostic station GR8-1200 NI or
Battery and electrical diagnostic analyzer EXP-800 NI. Re fer to the applicable Instruction Manual for proper
testing procedures.
Test result
NO PROBLEMS>>Charging system is normal and will also show “DIODE RIPPLE” test result.
NO VOLTAGE>>GO TO 4.
LOW VOLTAGE>>GO TO 12.
HIGH VOLTAGE>>GO TO 14.
EXCESSIVE RIPPLE, OPEN PHASE, OPEN DIODE or SHORTED DIODE>>Replace the generator. Refer
to CHG-32, "Removal and Installation"
. Perform “DIODE RIPPLE” test again using Multitasking
battery and electrical diagnostic station GR8-1200 NI or Battery and electrical diagnostic analyzer
EXP-800 NI to confirm repair.
4.INSPECTION WITH CHARGE WARNING LAMP (IGNITION SWITCH IS ON)
Turn the ignition switch ON.
Does the charge warning lamp illuminate?
YES >> GO TO 6.
NO >> GO TO 5.
5.“L” TERMINAL CIRCUIT (OPEN) INSPECTION
Check “L” terminal circuit (open). Refer to CHG-27, "Diagnosis Procedure"
.
Is the
“L” terminal circuit normal?
YES >> Replace generator. Refer to CHG-32, "Removal and Installation".
NO >> Repair as needed.
6.INSPECTION WITH CHARGE WARNING LAMP (IDLING)
Start the engine and run it at idle.
Does the charge warning lamp turn OFF?
YES >> GO TO 9.
NO >> GO TO 7.
7.“L” TERMINAL CIRCUIT (SHORT) INSPECTION
Check “L” terminal circuit (short). Refer to CHG-29, "Diagnosis Procedure"
.
Is the
“L” terminal circuit normal?
YES >> GO TO 8.
NO >> Repair as needed.
8.“S” TERMINAL CIRCUIT INSPECTION
Check “S” terminal circuit. Refer to CHG-30, "Diagnosis Procedure"
.
Is the
“S” terminal circuit normal?
YES >> GO TO 10.
