Circuit Diagnosis Procedure

Terminal "2" (S) is the power supply for the starter motor magnetic switch. Terminal 2 is supplied with power when the ignition switch is turned to the START position while the selector lever is in the P (Park) or N (Neutral) position.

1. CHECK STARTER MOTOR MAGNETIC SWITCH CIRCUIT 
   1. Turn ignition switch OFF.
   2. Disconnect starter motor connector E209 (VQ40DE) or F42 (VK56VD).
   3. Shift transmission into park or neutral.
   4. Check voltage between starter motor connector E209 (VQ40DE) or F42 (VK56VD) terminal 2 and ground with the ignition in START.

      (+)		(-)	Condition	Voltage
      Connector	Terminal
      E209 (VQ40DE)	2	Ground	Ignition switch in START position	Battery voltage
      F42 (VK56VD)

   Is the inspection result normal?

   YES

   Magnetic switch circuit is OK. Further inspection is necessary. Refer to Work Flow (With DSS-5000P NI) or Work Flow (Without DSS-5000P NI) .

   NO

   GO TO 2

2. CHECK CONNECTOR 
   1. Turn ignition switch OFF.
   2. Check the IPDM E/R connector E120 and starter motor connector E209 (VQ40DE) or F42 (VK56VD) 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 connector E209 (VQ40DE) or F42 (VK56VD).
   2. Check continuity between starter motor connector E209 (VQ40DE) or F42 (VK56VD) terminal 2 and IPDM E/R connector E120 terminal 19.

      Connector	Terminal	Connector	Terminal	Continuity
      E209 (VQ40DE)	2	E120	19	Yes
      F42 (VK56VD)

   3. Check continuity between starter motor connector E209 (VQ40DE) or F42 (VK56VD) terminal 2 and ground.

      Connector	Terminal	--	Continuity
      E209 (VQ40DE)	2	Ground	No
      F42 (VK56VD)

   Is the inspection result normal?

   YES

   Further inspection is necessary. Refer to Work Flow (With DSS-5000P NI) or Work Flow (Without DSS-5000P NI) .

   NO

   Repair the harness.
