COMPONENT DIAGNOSIS
B TERMINAL CIRCUIT
Description
INFOID:0000000005260634
Terminal "2" (B) is constantly supplied with battery power.
Diagnosis Procedure
INFOID:0000000005260635
Regarding Wiring Diagram information, refer to
STR-15, "Wiring Diagram - VQ40DE"
CAUTION:
Perform diagnosis under the condition that the engine cannot start by the following procedure.
1. Remove fuel pump fuse.
2. Crank or start the engine (where possible) until the fuel pressure is depleted.
1.
CHECK TERMINAL 2 POWER SUPPLY VOLTAGE
1. Turn ignition switch OFF.
2. Make sure that starter motor connector E210 terminal 2 connection is clean and tight.
3. Check voltage between starter motor connector E210 terminal 2
and ground.
Is there battery voltage present?
YES
>> GO TO 2
NO
>> Check harness between battery and starter motor for
open circuit.
2.
CHECK BATTERY CABLE (VOLTAGE DROP TEST)
1. Shift the transmission into park or neutral.
2. Check voltage between battery positive terminal and starter
motor connector E210 terminal 2 while cranking the engine.
Is the voltage drop less than 0.2V?
YES
>> GO TO 3
NO
>> Check harness between the battery and the starter
motor for high resistance.
3.

S CONNECTOR CIRCUIT
S CONNECTOR CIRCUIT
Description
INFOID:0000000005260636
Terminal "1" (S) is the power supply for the starter motor magnetic switch. Terminal 1 is supplied with power
when the ignition switch is turned to the START position while the selector lever is in the P or N position.
Diagnosis Procedure - VQ40DE
INFOID:0000000005260637
Regarding Wiring Diagram information, refer to
STR-15, "Wiring Diagram - VQ40DE"
.
CAUTION:
Perform diagnosis under the condition that engine cannot start by the following procedure.
1. Remove fuel pump fuse.
2. Crank or start the engine (where possible) until the fuel pressure is released.
1.
CHECK STARTER MOTOR MAGNETIC SWITCH CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect starter motor connector E207.
3. Shift transmission into park or neutral.
4. Check voltage between starter motor harness connector E207
terminal 1 and ground with the ignition in START.
Is battery voltage present?
YES
>> Magnetic switch circuit is OK. Further inspection necessary. Refer to
.
NO
>> GO TO 2
2.
CHECK CONNECTOR
1. Turn ignition switch OFF.
2. Check the IPDM E/R harness connector E120 and starter motor harness connector E207 for damage,
bent pins and loose connections.
Is the inspection result normal?
YES
>> GO TO 3
NO
>> Repair the terminal and connector.
3.
CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect IPDM E/R connector E120 and starter motor con-
nector E207.
2. Check continuity between starter motor harness connector E207
(A) terminal 1 and IPDM E/R harness connector E120 (B) termi-
nal 19.
3. Check continuity between starter motor harness connector E207
(A) terminal 1 and ground.
