Diagnostic Procedure 2, Check "S" Terminal Circuit
WARNING: This page is about a different car, the 2004 Nissan Pathfinder, 2003 Nissan Pathfinder, and 2002 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
- Remove the fuel pump fuse. See COMPONENT LOCATIONS .
- Crank or start the engine (if possible) until the fuel pressure is released.
- Turn the ignition switch OFF.
- Disconnect starter motor connector E109 (for 2002 model vehicles) or E147 (for 2003 and 2004 model vehicles). See COMPONENT LOCATIONS .
- Check voltage between starter motor connector E109 (for 2002 model vehicles) or E147 (for 2003 and 2004 model vehicles) terminal "S" and ground using a digital circuit tester. With ignition switch "ON", battery voltage should exist. See Fig 1. If voltage is as specified, go to next step. If voltage is as not specified, check:
- 40-Amp fusible link (letter "E" , located in fuse and fusible link box).
- Park/Neutral Position relay
- Harness for open or short.
- Connect starter motor connector E109 (for 2002 model vehicles) or E147 (for 2003 and 2004 model vehicles). Check voltage between starter motor connector E109 (for 2002 model vehicles) or E147 (for 2003 and 2004 model vehicles) terminal "S" and battery positive terminal using a digital tester. With ignition switch in "START" position, voltage should be less than 1.0 volt. See Fig 1. 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.
