• “B” terminal circuit. Refer to 

STR-21, "Diagnosis Procedure"

.

• “S” terminal circuit. Refer to 

STR-23, "Diagnosis Procedure"

.

Are these inspection results normal?

YES-1 >> Type 1: Replace starter motor.
YES-2 >> Type 2: GO TO 10.
NO

>> Repair as needed.

10.

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 11.

NO

>> Replace magnetic switch.

11.

PINION AND RING GEAR ENGAGEMENT CHECK

Check condition of pinion and ring gear mesh.

Is the inspection result normal?

YES

>> GO TO 13.

NO

>> GO TO 12.

12.

CHECK STARTER MOTOR UNIT

Check the following.
• Adjust pinion movement. Refer to 

STR-29, "MR20DD : Inspection"

.

• Check pinion moving mechanism.
• Check ring gear.
Are these inspection results normal?

YES

>> INSPECTION END

NO

>> Repair or replace, if necessary.

13.

CHECK STARTER MOTOR UNIT

Check that the starter motor runs when connecting the positive terminal (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.

Diagnosis Procedure

INFOID:0000000010430895

CAUTION:

• Perform diagnosis under the condition that engine cannot start by the following procedure.
- Remove fuel pump fuse.
- Crank or start the engine (where possible) until the fuel pressure is released.
• For models with stop/start system, erase the starter operation counter when the starter motor con-

nector is disconnected. Refer to 

ECH-120, "Work Procedure"

 (HR engine), 

ECK-146, "Work Proce-

dure"

 (K9K engine), 

EC9-155, "Work Procedure"

 (R9M engine) or 

ECM-203, "Work Procedure"

(MR16DDT engine).

1.

CHECK “B” TERMINAL CIRCUIT 1

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.

Except for MR engine

For MR engine

Is the inspection result normal?

YES

>> GO TO 2.

NO-1

>> For models with stop/start system: GO TO 4.

NO-2

>> For models without stop/start system: 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. (CVT models)
Keep depressing clutch pedal fully. (M/T models)

2.

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

Except for MR engine

For MR engine

Is the inspection result normal?

YES

>> GO TO 3.

NO

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