CHECK MAGNETIC SWITCH OPERATION SOUND

Check that a magnetic switch operation sound can be heard when the ignition switch is set at the starting posi-
tion. 

Does magnetic switch operation sound occur?

YES

>> GO TO 10.

NO

>> Replace magnetic switch.

10.

PINION AND RING GEAR ENGAGEMENT CHECK

Check condition of pinion and ring gear mesh.
Is the inspection result normal?

YES

>> GO TO 12.

NO

>> GO TO 11.

11.

CHECK STARTER MOTOR UNIT

Check the following.
• Adjust pinion movement. Refer to 

STR-19, "Inspection and Adjustment"

.

• Check pinion moving mechanism.
• Check ring gear.

Are these inspection results normal?

YES

>> INSPECTION END

NO

>> Repair or replace, if necessary.

12.

CHECK STARTER MOTOR UNIT

Check that the starter motor runs when connecting the positive ter-
minal (12 V) to starter motor terminal M and the negative terminal
(ground) to starter motor body. 
Does the starter motor run?

YES

>> Replace magnetic switch.

NO

>> Repair starter motor.

B TERMINAL CIRCUIT

DTC/CIRCUIT DIAGNOSIS

B TERMINAL CIRCUIT

Description

INFOID:0000000006057523

The “B” terminal is constantly supplied with battery power.

Diagnosis Procedure

INFOID:0000000006057524

CAUTION:

Perform diagnosis under the condition that engine cannot start by the following procedure.
1.

Remove fuel pump fuse.

2.

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

1.

CHECK “B” TERMINAL CIRCUIT

1.

Turn ignition switch OFF.

2.

Check that starter motor “B” terminal connection is clean and tight.

3.

Check voltage between starter motor “B” terminal and ground.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Check harness between battery and starter motor for open circuit.

2.

CHECK BATTERY CABLE CONNECTION STATUS (VOLTAGE DROP TEST)

1.

Shift selector lever to “P” or “N” position. (A/T models)

2.

Check voltage between battery positive terminal and starter motor “B” terminal.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Check harness between the battery and the starter motor for poor continuity.

3.

CHECK GROUND CIRCUIT STATUS (VOLTAGE DROP TEST)

1.

Shift selector lever to “P” or “N” position. (A/T models)

2.

Check voltage between starter motor case and battery negative terminal.

Is the inspection result normal?

YES

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

STR-11, "Work Flow"

.

NO

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

S TERMINAL CIRCUIT

Description

INFOID:0000000006057525

The starter motor magnetic switch is supplied with power when the ignition switch is turned to the START posi-
tion while the selector lever is in the P or N position for A/T models.

Diagnosis Procedure

INFOID:0000000006057526

CAUTION:

Perform diagnosis under the condition that engine cannot start by the following procedure.
1.

Remove fuel pump fuse.

2.

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

1.

INSPECTION START

Check which type of transmission the vehicle is equipped with.

Which type of transmission?

A/T

>> GO TO 2.

M/T

>> GO TO 4.

2.

CHECK “S” TERMINAL CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect starter motor connector.

3.

Shift selector lever to “P” or “N” position.

4.

Check voltage between starter motor harness connector and ground.

Is the inspection result normal?

YES

>> “S” terminal circuit is OK. Further inspection is necessary. Refer to 

STR-11, "Work Flow"

.

NO

>> GO TO 3.

3.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1.

Disconnect IPDM E/R connector.

2.

Check continuity between starter motor harness connector and IPDM E/R harness connector.

Is the inspection result normal?

YES

>> Further inspection is necessary. Refer to 

STR-11, "Work Flow"

. 

NO

>> Repair the harness.
