Diagnosis Procedure
Regarding Wiring Diagram information, refer to " WIRING DIAGRAM ".
| CAUTION | Perform diagnosis under the condition that the engine cannot start by the following procedure. Remove fuel pump fuse. Crank or start the engine (where possible) until the fuel pressure is depleted. |

- CHECK TERMINAL B POWER SUPPLY VOLTAGE Turn ignition switch OFF. Make sure that starter motor connector F27 terminal B connection is clean and tight. Check voltage between starter motor connector F27 terminal B and ground. B - ground Battery voltage Is there battery voltage present? YES >> GO TO 2 NO >> Check harness between battery and starter motor for open circuit.
- CHECK BATTERY CABLE (VOLTAGE DROP TEST) Shift CVT selector lever to "P" or "N" position. Check voltage between battery positive terminal and starter motor connector F27 terminal B while cranking the engine. While cranking the engine Terminal B - B+ terminal Less than 0.5V Is the voltage drop less than 0.5V? YES >> GO TO 3 NO >> Check harness between the battery and the starter motor for high resistance.
- CHECK GROUND CIRCUIT STATUS (VOLTAGE DROP TEST) Shift CVT selector lever to "P" or "N" position. Check voltage between starter motor case and battery negative terminal while cranking the engine. While cranking the engine Starter case - B-terminal Less than 0.2V Is the voltage drop less than 0.2V? YES >> Terminal B circuit is OK. Further inspection necessary. Refer to " «WORK FLOW»(ref-388059-S01691071192011022800000) ". NO >> Check the starter motor case to engine mounting for high resistance.

- CHECK "S" CONNECTOR CIRCUIT Turn ignition switch OFF. Disconnect starter motor connector F28. Shift CVT selector lever to "P" or "N" position. Check voltage between starter motor harness connector F28 terminal S and ground with the ignition in START. With ignition switch in START S - ground Battery voltage Is battery voltage present? YES >> "S" circuit is OK. Further inspection necessary. Refer to " «WORK FLOW»(ref-388059-S01691071192011022800000) ". NO >> GO TO 2
- CHECK CONNECTOR Turn ignition switch OFF. Check the following terminals and connectors for damage, bent pins and loose connections. IPDM E/R harness connector F10 Starter motor harness connector F28 Is the inspection result normal? YES >> GO TO 3 NO >> Repair the terminal and connector.
- CHECK HARNESS CONTINUITY (OPEN CIRCUIT) Disconnect the following harness connectors. IPDM E/R connector F10 Starter motor connector F28 Check continuity between starter motor harness connector F28 terminal S and IPDM E/R harness connector F10 terminal 80. S - 80 Continuity exists Is there proper continuity between the two pins? YES >> Further inspection necessary. Refer to " «WORK FLOW»(ref-388059-S01691071192011022800000) ". NO >> Repair the harness.
