Diagnosis Procedure
INFOID:0000000010957648
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
.
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.
For QR engine
For MR engine
For R9M 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.

B TERMINAL CIRCUIT
For MR engine
For R9M engine
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. (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.
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.
Is the inspection result normal?
YES
>> Replace engine restart bypass relay. Refer to
EC-1230, "Removal and Installation"
