< 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
.
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"

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
(K9K engine),
(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
.
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
