DIAGNOSTIC PROCEDURE 1
Check “B” Terminal Circuit
1. CHECK POWER SUPPLY FOR STARTER MOTOR “B” TERMINAL
1. Remove fuel pump fuse.
2. Crank or start the engine (where possible) until the fuel pressure is released.
3. Turn ignition switch OFF.
4. Make sure that the starter motor B terminal E313 terminal 2 (B)
*1 or (B/R)*2 connection is clean and tight.
5. Check voltage between starter motor B terminal E313 terminal 2
(B)
*1 or (B/R)*2 and ground using a digital circuit tester.
NOTE:
*1: VK45DE, *2: VQ35DE
OK or NG
OK >> GO TO 2.
NG >> Check harness between the battery and the starter
motor for open circuit.
2. CHECK BATTERY HARNESS CONNECTION (VOLTAGE DROP TEST)
Check voltage between starter motor B terminal E313 terminal 2
(B)
*1 or (B/R)*2 and battery positive terminal using a digital circuit
tester.
NOTE:
*1: VK45DE, *2: VQ35DE
OK or NG
OK >> GO TO 3.
NG >> Check harness between the battery and the starter
motor for poor continuity.
3. CHECK STARTER MOTOR GROUND CIRCUIT (VOLTAGE DROP TEST)
1. Turn ignition switch OFF.
2. Check voltage between starter motor case and battery negative
terminal using a digital circuit tester.
OK or NG
OK >> Starter motor “B” terminal circuit is OK. Further inspec-
tion necessary. Refer to SC-14, "
WORK FLOW" .
NG >> Check the starter motor case and ground for poor conti-
nuity. Battery voltage should exist.

When the ignition switch is in START position,
Voltage: Less than 0.5V
PKIA2370E
When the ignition switch is in START position,
Voltage: Less than 0.2V

DIAGNOSTIC PROCEDURE 2
Check “S” Connector Circuit
1. CHECK POWER SUPPLY FOR STARTER MOTOR “S” CONNECTOR
1. Remove fuel pump fuse.
2. Crank or start the engine (where possible) until the fuel pressure is released.
3. Turn ignition switch OFF.
4. Disconnect starter motor S connector.
5. Check voltage between starter motor harness connector E312
*1
or F33*2 terminal 1 (B) and ground using a digital circuit tester.
NOTE:
*1: VK45DE, *2: VQ35DE
OK or NG
OK >> GO TO 2.
NG >> Check the following.

40A fusible link (letter F , located in fuse and fusible
link box)

Ignition switch

Starter relay [within the IPDM E/R (intelligent power distribution module engine room)].

Harness for open or short
2. CHECK “S” TERMINAL CONNECTION (VOLTAGE DROP TEST)
1. Turn ignition switch OFF.
2. Connect starter motor S connector.
3. Check voltage between starter motor harness connector E312
*1
or F33*2 terminal 1 (B) and battery positive terminal using a dig-
ital circuit tester.
NOTE:
*1: VK45DE, *2: VQ35DE
OK or NG
OK >> Starter motor “S” connector circuit is OK. Further inspec-
tion necessary. Refer to SC-14, "
WORK FLOW" .
NG >> Check harness between the battery and the starter motor “S” connector for poor continuity.
