DIAGNOSTIC PROCEDURE 1
Check Starter Motor Circuit

OK >> GO TO 2.
NG >> Check harness between the battery and the starter motor for open circuit. OK >> GO TO 3.
NG >> Check harness between the battery and the starter motor for poor continuity. OK >> Starter motor ground circuit is OK. Further inspection is
necessary. Refer to "WORK FLOW".
NG >> Check harness between the starter motor case and
ground for poor continuity.
DIAGNOSTIC PROCEDURE 2
Check Magnetic Switch Circuit OK >> GO TO 2.
NG >> Check the following:
• 40A fusible link (letter h, located in fuse and fusible
link box)
Battery voltage should exist

• 10A fuse (No. 49, M/T model
s, located in the IPDM E/R)
• 15A fuse (No. 52, located in the IPDM E/R)
• 20A fuse (No. 53, located in the IPDM E/R)
• PNP switch, clutch interlock switch or TCM depending on equipment
• Ignition switch
• Ignition relay IPDM E/R
• Starter relay IPDM E/R
• Starter relay request ON signal from BCM
• Harness for open or short circuit OK >> Magnetic switch circuit is
OK. Further inspection is nec-
essary. Refer to "WORK FLOW".
NG >> Check harness, components and connections between the battery and the magnetic switch for poor continuity.

CHARGING SYSTEM
System Description INFOID:0000000004306825
The generator provides DC voltage to operate the vehicl e's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times to generator terminal 3 through
• 10A fuse (No. 29, located in the fuse and fusible link box).
Power is supplied through terminal 1 to charge the batte ry and operate the vehicle's electrical system. Output
voltage is monitored at terminal 3 by the IC regulator. The charging circuit is protected by the 120A fusible link
[letter a , located in the fusible link box (battery)].
Ground is supplied
• to generator terminal 5
• through body ground F5, and
• through the generator case to the cylinder block
With the ignition switch in the ON or START position, power is supplied
• through 10A fuse [No. 3, located in the fuse block (J/B)]
• to combination meter terminal 28 for the charge warning lamp.
The IC regulator controls ground to terminal 38 of the combination meter through terminal 2 of the generator.
When the ignition is turned on and power becomes availabl e at terminal 2, this "wakes up" the regulator. The
regulator monitors charge output and grounds terminal 2 or leaves it open depending on charge output. With
power and ground supplied, the charge warning lamp will il luminate. When the generator is providing sufficient
voltage, the ground is opened and the charge warning lamp will go off.
If the charge warning lamp illuminates with the engine running, a malfunction is indicated.

DIAGNOSTIC PROCEDURE 1
Check Charge Warning Lamp Circuit OK >> GO TO 2.
NG >> Repair terminal 2 connection. Confirm repair by performing complete Starting/Charging system test. Refer to diagnostic station instruction manual. B

OK >> GO TO "WORK FLOW" .
NG >> Check the following.
• 10A fuse [No. 3, located in fuse block (J/B)]
• CHARGE lamp
• Harness for open or short between combination meter and fuse
• Harness for open or short between combination meter and generator
DIAGNOSTIC PROCEDURE 2
Check Battery Circuit OK >> GO TO 2.
NG >> Repair terminal 1 connection. Confirm repair by performing complete Starting/Charging system
test. Refer to diagnostic station instruction manual. OK >> GO TO 3.
NG >> Check the following. • 120A fusible link [letter a , located in fusible link box
(battery)]
• Harness for open or short between generator and fus- ible link OK >> Replace the generator. Refer to
SC-25, " Removal and
Installation " . Confirm repair by performing complete
Starting/Charging system test. Refer to diagnostic sta-
tion instruction manual.
NG >> Check harness between the battery and the generator for poor continuity.
DIAGNOSTIC PROCEDURE 3
Check Voltage Regulator Circuit CHARGE lamp should light up.
