B TERMINAL CIRCUIT
DescriptionINFOID:0000000012432072
Terminal “B” is constantly supplied with battery power.
Diagnosis ProcedureINFOID:0000000012432073
Regarding Wiring Diagram information, refer to
STR-10, "Wiring Diagram - With Intelligent Key System" or
STR-16, "
Wiring Diagram - Without Intelligent Key System".
CAUTION:
Perform diagnosis under the cond ition that the 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 “B” TERMINAL CIRCUIT
1. Turn ignition switch OFF.
2. Check that starter motor B” terminal connection is clean and tight.
3. Check voltage between starter motor connector F27 and ground.
Is the inspection result normal?
YES >> GO TO 2.
NO >> 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 (P ark) or N (Neutral) position.
2. Check voltage between battery positive terminal and starter motor B terminal.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Check harness between the battery and starter motor for continuity.
3.CHECK GROUND CIRCUIT STATUS (VOLTAGE DROP TEST)
1. Shift selector lever to P (P ark) or N (Neutral) position.
2. Check voltage between starter motor case and battery negative terminal.
Is the inspection result normal?

S CONNECTOR CIRCUIT
DescriptionINFOID:0000000012432074
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:0000000012432075
Regarding Wiring Diagram information, refer to
STR-10, "Wiring Diagram - With Intelligent Key System" or
STR-16, "
Wiring Diagram - Without Intelligent Key System".
CAUTION:
Perform diagnosis under the cond ition 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 connector F28 and ground.
Is the inspection result normal?
YES >> “S” circuit is OK. Further inspection is necessary. Refer to STR-21, "Work Flow (With GR8-1200
NI)" or STR-25, "Work Flow (Without GR8-1200 NI)".
NO >> GO TO 2.
2.CHECK HARNESS CONTINUI TY (OPEN CIRCUIT)
1. Disconnect IPDM E/R connector.
2. Check continuity between starter motor harnes s connector F28 and the IPDM E/R harness connector
E43.
3. Check continuity between starter motor connector F28 terminal S and ground.
Is the inspection result normal?
YES >> Further inspection is necessary. Refer to STR-21, "Work Flow (With GR8-1200 NI)" or STR-25,
"Work Flow (Without GR8-1200 NI)".
NO >> Repair or replace the harness or connectors.
