Check Magnetic Switch Circuit

WARNING: This page is about a different car, the 2007 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.

CHECK POWER SUPPLY TO MAGNETIC SWITCH
1. Remove the fuel pump fuse.
2. Crank or start the engine (where possible) until the fuel pressure is released.
3. Turn the ignition switch OFF.
4. Disconnect starter motor connector E207.
5. Check voltage between starter motor connector E207 terminal 1 and ground using a digital circuit tester.
  Ignition switch in START. : Battery voltage

OK or NG

OK: GO TO 2.

NG: Check the following.
- 40A fusible link (letter j , located in fuse and fusible link box)
- Ignition switch
- Starter relay [within the intelligent power distribution module engine room (IPDM E/R)]
- Starter relay request ON signal
- Harness for open or short
CHECK VOLTAGE DROP ON MAGNETIC SWITCH CIRCUIT
1. Turn the ignition switch OFF.
2. Connect starter motor connector E207.
3. Check voltage between starter motor connector E207 terminal 1 and battery positive terminal using a digital circuit tester.
  Ignition switch in START. : Less than 1V

OK or NG

OK: Magnetic switch circuit is OK. Further inspection is necessary. Refer to "WORK FLOW ".

NG: Check harness between the battery and the magnetic switch for poor continuity.
