< DTC/CIRCUIT DIAGNOSIS >

B TERMINAL CIRCUIT

3.

CHECK GROUND CIRCUIT 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 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-19, "Work Flow"

.

NO

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

4.

CHECK “B” TERMINAL CIRCUIT 2

1.

Disconnect starter connector and engine restart bypass relay connector.

2.

Check continuity between starter motor harness connector and engine restart bypass relay harness con-
nector.

Except for MR16DDT engine

For MR16DDT engine

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Repair or replace harness.

5.

CHECK ENGINE RESTART BYPASS RELAY CIRCUIT

Check voltage between engine restart bypass relay harness connector and ground.

Except for MR16DDT engine

For MR16DDT engine

Is the inspection result normal?

YES

>> Replace engine restart bypass relay. Refer to 

ECH-322, "Removal and Installation"

 (HR engine),

ECK-402, "Removal and Installation"

 (K9K engine), 

EC9-413, "Removal and Installation"

 (R9M

engine) or 

ECM-619, "Removal and Installation"

 (MR16DDT engine).

NO

Diagnosis Procedure

INFOID:0000000010430896

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 “S” TERMINAL CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect starter motor connector.

3.

Shift selector lever to “P” or “N” position. (CVT models)
Keep depressing clutch pedal fully. (M/T models)

4.

Check voltage between starter motor harness connector and ground.

Except for MR engine

For MR engine

Is the inspection result normal?

YES

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

STR-19, "Work Flow"

.

NO

>> GO TO 2.

2.

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.

Except for MR engine

For MR engine

Is the inspection result normal?

YES

>> Further inspection is necessary. Refer to 

SEC-78, "Work Flow"

 (With Intelligent Key System) or

SEC-237, "Work Flow"

 (Without Intelligent Key System).

NO

>> Repair or replace harness.
