S CONNECTOR CIRCUIT
S CONNECTOR CIRCUIT
DescriptionINFOID:0000000009461231
The starter motor magnetic switch is supplied with power when the ignition switch is turned to the START posi-
tion while the selector lever is in the P (Park) or N (Neutral) position.
Diagnosis ProcedureINFOID:0000000009461232
Regarding Wiring Diagram information, refer to STR-7, "Wiring Diagram".
CAUTION:
Perform diagnosis under the condi tion that engine cannot start by the following procedure.
1. Remove fuel pump fuse.
2. Crank or start the engine (where possi ble) until the fuel pressure is released.
1.CHECK “S” CONNECTOR CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect starter motor connector.
3. Shift selector lever to “P” (Park) or “N” (Neutral) position.
4. Check voltage between starter motor harness con nector F28 (QR25DE) or F81 (VQ35DE) and ground.
Is the inspection result normal?
YES >> “S” circuit is OK. Further inspection is necessary. Refer to STR-12, "Work Flow (With GR8-1200
NI)" or STR-16, "Work Flow (Without GR8-1200 NI)".
NO >> GO TO 2.
2.CHECK HARNESS CONTI NUITY (OPEN CIRCUIT)
1. Disconnect IPDM E/R connector.
2. Check continuity between starter motor harness connector F28 (QR25DE) or F81 (VQ35DE) and the
IPDM E/R harness connector F10.
Is the inspection result normal?
YES >> Further inspection is necessary. Refer to STR-12, "Work Flow (With GR8-1200 NI)" or STR-16,
"Work Flow (Without GR8-1200 NI)".
NO >> Repair or replace the harness or connectors.
