Diagnostic Procedure 2, Check "S" Terminal Circuit

WARNING: This page is about a different car, the 2004 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.
  1. Remove the fuel pump fuse. See COMPONENT LOCATIONS . Crank or start the engine (if possible) until the fuel pressure is released.
  2. Turn the ignition switch "OFF".
  3. Disconnect starter motor connector F28 terminal "S" (Black/White wire) connector. See WIRING DIAGRAMS . Check voltage between starter motor connector F28 terminal "S" (Black/White wire) and ground using a digital circuit tester. With ignition switch "START", battery voltage should exist. If voltage is as specified, go to next step. If voltage is as not specified, check:
    • 40A fusible link (letter m, located in fuse and fusible link block).
    • Starter relay [within the IPDM E/R (intelligent power distribution module engine room)].
    • Harness for open or short.
  4. Connect starter motor connector. Check voltage between starter motor connector F28 terminal "S" (Black/White wire) and battery positive terminal using a digital tester. With ignition switch in "START" position, voltage should be less than 1 volt. Starter motor "S" terminal circuit is OK. Further inspection is necessary. Refer to WORK FLOW . If voltage is as not specified, check harness between the battery and the starter motor "S" terminal for poor continuity.
