System DescriptionINFOID:0000000001328246
Power is supplied at all times
 through 40A fusible link (letter F, located in the fuse and fusible link block)
 to ignition switch terminal 1,
 through 15A fuse (No. 78, located in the IPDM E/R)
 to CPU of IPDM E/R,
 through 10A fuse (No. 71, located in the IPDM E/R)
 to CPU of IPDM E/R.
When the selector lever in the P or N position, power is supplied
 from TCM, and through A/T assembly terminal 9
 to IPDM E/R terminal 53.
Ground is supplied
 to IPDM E/R terminals 38, 50 and 60
 from grounds E21, E50 and E51.
With the ignition switch in the START position, and provided that the IPDM E/R receives a starter relay ON sig-
nal from the CAN lines, the IPDM E/ R is energized and power is supplied
 from ignition switch terminal 5
 to IPDM E/R terminal 4 and
 through IPDM E/R terminal 3
 to starter motor terminal 1.
The starter motor plunger closes and provides a clos ed circuit between the battery and starter motor. The
starter motor is grounded to the engine block. With power and ground supplied, cranking occurs and the
engine starts.

1.CHECK “B” TERMINAL CIRCUIT
1. Turn ignition switch OFF.
2. Make sure that starter motor “B” terminal E313 terminal 2 connection is clean and tight.
3. Check voltage between starter motor “B” terminal E313 terminal 2 and ground.
OK or NG
OK >> GO TO 2.
NG >> Check harness between battery and starter motor for open circuit.
2.CHECK BATTERY CABLE CONNECTION STATUS (VOLTAGE DROP TEST)
1. Shift A/T selector lever to “P” or “N” position.
2. Check voltage between starter motor “B” terminal E313 terminal 2 and battery positive terminal.
OK or NG
OK >> GO TO 3.
NG >> Check harness between battery and starter motor for poor continuity.
3.CHECK GROUND CIRCUIT STATUS (VOLTAGE DROP TEST)
1. Turn ignition switch OFF.
2. Shift A/T selector lever to “P” or “N” position.
3. Check voltage between starter motor case and battery negative terminal.
OK or NG
OK >> “B” terminal circuit is OK. Further inspection necessary. Refer to SC-10, "
Trouble Diagnosis with Starting/Charg-
ing System Tester (Starting)".
NG >> Check starter motor case and ground for poor continuity.
DIAGNOSTIC PROCEDURE 2
Check “S” Connector Circuit
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
