Check Starter Motor 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 STARTER MOTOR
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. Check that the starter motor connector E210 connection is clean and tight.
5. Check voltage between starter motor connector E210 terminal 2 and ground using a digital circuit tester.
  Battery voltage should exist.

OK or NG

OK: GO TO 2.

NG: Check harness between the battery and the starter motor for open circuit.
CHECK VOLTAGE DROP ON STARTER MOTOR CIRCUIT
Check voltage between starter motor connector E210 terminal 2 and battery positive terminal using a digital circuit tester.

Ignition switch in START. : Less than 0.5V

OK or NG

OK: GO TO 3.

NG: Check harness between the battery and the starter motor for poor continuity.
CHECK VOLTAGE DROP ON STARTER MOTOR GROUND CIRCUIT
Check voltage between starter motor case and battery negative terminal using a digital circuit tester.

Ignition switch in START. : Less than 0.2V

OK or NG

OK: Starter motor ground circuit is OK. Further inspection is necessary. Refer to "WORK FLOW ".

NG: Check harness between the starter motor case and ground for poor continuity.
