System Description

EKS00FTK

Power is supplied at all times

●

to starter motor terminal 2 and

●

through 40A fusible link (letter j , located in the fuse and fusible link box)

●

to ignition switch terminal B.

With the ignition switch in the START position, power is supplied

●

from ignition switch terminal ST

●

to IPDM E/R terminal 21.

With the ignition switch in the ON or START position, power is supplied to IPDM E/R (intelligent power distribu-
tion module engine room) CPU.
With the selector lever in the P or N position, power is supplied

●

through A/T assembly terminal 9

●

to IPDM E/R terminal 48.

Ground is supplied at all times

●

to IPDM E/R terminals 38 and 59

●

from body grounds E9, E15 and E24.

Provided that the IPDM E/R receives a starter relay request ON signal from the BCM over the CAN communi-
cation lines, the IPDM E/R grounds the starter relay and power is supplied

●

from terminal 19 of the IPDM E/R

●

to terminal 1 of the starter motor.

The starter motor plunger closes and provides a closed circuit between the battery and the starter motor. The
starter motor is grounded to the cylinder block. With power and ground supplied, the starter motor operates.

Trouble Diagnoses with Battery/Starting/Charging System Tester

EKS00FTM

NOTE:
To ensure a complete and thorough diagnosis, the battery, starter and generator test segments must be done
as a set from start to finish.

1.

Turn off all loads on the vehicle electrical system.

2.

Perform battery test with Battery/Starting/Charging system
tester. Refer to 

SC-6, "Trouble Diagnoses with Battery/Starting/

Charging System Tester"

 .

3.

Press “ENTER” to begin the starting system test.

4.

Start the engine.

5.

Diagnosis result is displayed on the tester. Refer to 

SC-13,

"DIAGNOSTIC RESULT ITEM CHART"

 .

NOTE:

●

If the starter performs normally but the engine does not start,
perform engine diagnosis.

●

For intermittent “NO CRANK” or “NO STARTER OPERA-
TION” incidents, refer to 

SC-16, "DIAGNOSTIC PROCE-

DURE 2"

 .

Service procedure

CRANKING VOLTAGE NORMAL

Go to 

SC-14, "WORK FLOW"

 .

CRANKING VOLTAGE LOW

CHARGE BATTERY

Perform the slow battery charging procedure. (Initial rate of charge is 10A for 12 hours.) Per-
form battery test again with Battery/Starting/Charging system tester. Refer to

SC-6, "Trouble 

Diagnoses with Battery/Starting/Charging System Tester"

  .

REPLACE BATTERY

Before replacing battery, clean the battery cable clamps and battery posts. Perform battery 
test again with Battery/Starting/Charging system tester. Refer to 

SC-6, "Trouble Diagnoses 

with Battery/Starting/Charging System Tester"

 . If second test result is “REPLACE BAT-

TERY”, then do so. Perform battery test again to confirm repair.

DIAGNOSTIC PROCEDURE 1
Check Starter Motor Circuit

1. 

CHECK POWER SUPPLY TO STARTER MOTOR

1.

Remove the fuel pump fuse.

2.

Crank or start the engine (where possible) until the fuel pressure is released.

3.

Turn the ignition switch OFF.

4.

Check that the starter motor connector E210 connection is clean and tight.

5.

Check voltage between starter motor connector E210 terminal 2
and ground using a digital circuit tester.

OK or NG

OK

>> GO TO 2.

NG

>> Check harness between the battery and the starter

motor for open circuit.

2. 

CHECK VOLTAGE DROP ON STARTER MOTOR CIRCUIT

Check voltage between starter motor connector E210 terminal 2 and
battery positive terminal using a digital circuit tester.

OK or NG

OK

>> GO TO 3.

NG

>> Check harness between the battery and the starter

motor for poor continuity.

3. 

CHECK VOLTAGE DROP ON STARTER MOTOR GROUND CIRCUIT

Check voltage between starter motor case and battery negative ter-
minal using a digital circuit tester.

OK or NG

OK

>> Starter motor ground circuit is OK. Further inspection is

necessary. Refer to 

SC-14, "WORK FLOW"

 .

NG

>> Check harness between the starter motor case and

ground for poor continuity.

Battery voltage should 
exist.
