DIAGNOSTIC PROCEDURE 1
Check “B” Terminal Circuit

1. 

CHECK POWER SUPPLY FOR STARTER MOTOR “B” TERMINAL

1.

Remove fuel pump fuse.

2.

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

3.

Turn ignition switch OFF.

4.

Make sure that the starter motor “B” terminal E203 terminal 2 (B/R) connection is clean and tight.

5.

Check voltage between starter motor “B” terminal E203 terminal
2 (B/R) and ground using.

OK or NG

OK

>> GO TO 2.

NG

>> Check harness between battery and starter motor for

open circuit.

2. 

CHECK BATTERY CABLE CONNECTION (VOLTAGE DROP TEST)

Check voltage between starter motor “B” terminal E203 terminal 2
(B/R) and battery positive terminal.

OK or NG

OK

>> GO TO 3.

NG

>> Check harness between battery and starter motor for

poor continuity.

3. 

CHECK STARTER MOTOR GROUND CIRCUIT (VOLTAGE DROP TEST)

1.

Turn ignition switch OFF.

2.

Check voltage between starter motor case and battery negative
terminal using.

OK or NG

OK

>> “B” terminal circuit is OK. Further inspection necessary.

Refer to 

SC-16, "WORK FLOW"

 .

NG

>> Check starter motor case and ground for poor continuity.

DIAGNOSTIC PROCEDURE 2
Check “S” Connector Circuit

1. 

CHECK POWER SUPPLY FOR STARTER MOTOR “S” TERMINAL

1.

Remove fuel pump fuse.

2.

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

3.

Turn ignition switch OFF.

4.

Disconnect starter motors connector.

5.

Check voltage between starter motor connector F9 terminal 1
(B/Y) and ground.

OK or NG

OK

>> “S” connector circuit is OK. Further inspection neces-

sary. Refer to 

SC-16, "WORK FLOW"

 .

NG

>> Check the following.

●

40A fusible link (letter M, located in fuse and fusible
link block)

●

Ignition switch

●

Starter relay (within the IPDM E/R)

●

Harness between starter motor and IPDM E/R

Removal and Installation 

NKS000F0

REMOVAL 

1.

Open the driver and front passenger window, and then disconnect the battery cable from the negative ter-
minal.   

CAUTION:

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent
any interference between the window edge and the vehicle when the door is opened/closed. Dur-
ing normal operation, the window slightly raises and lowers automatically to prevent any window
to vehicle interference. The automatic window function will not work with the battery discon-
nected.

2.

Remove engine rear undercover, using power tools.

3.

Disconnect “S” connector.

4.

Remove “B” terminal nut.

5.

Remove starter motor mounting bolts and harness connector
clip bracket, using power tools.

6.

Remove starter motor downward.

INSTALLATION

Installation is the reverse order of removal.

CAUTION:

Be sure to tighten “B” terminal nut carefully.
