DIAGNOSTIC PROCEDURE 1
Check Starter Motor Circuit
1.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 F27 connection is clean and tight.

STARTING SYSTEM
5. Check voltage between starter motor connector F27 terminal Band ground using a digital circuit tester.
OK or NG
OK >> GO TO 2.
NG >> Check harness between the battery and the starter motor for open circuit.
2.CHECK VOLTAGE DROP ON STARTER MOTOR CIRCUIT
1. Check voltage between starter motor connector F27 terminal B and battery positive terminal using a digital circuit tester.
OK or NG
OK >> GO TO 3.
NG >> Check harness between the battery and the starter motor for poor continuity.
3.CHECK VOLTAGE DROP ON STARTER MOTOR GROUND CIRCUIT
1. Check voltage between starter motor case and battery negative terminal using a digital circuit tester.
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.
DIAGNOSTIC PROCEDURE 2
Check Magnetic Switch Circuit
1.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 F28.
5. Check voltage between starter motor connector F28 terminal S and ground using a digital circuit tester.
OK or NG
OK >> GO TO 2.
NG >> Check the following: • 40A fusible link (letter  h, located in fuse and fusible
link box)
