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) (VK45DE) or (B/R) (VQ35DE) connec- tion is clean and tight.
5. Check voltage between starter motor “B” terminal E313 terminal 2 (B) (VK45DE) or (B/R) (VQ35DE) and ground.
OK or NG
OK >> GO TO 2.
NG >> Check harness between battery and starter motor for
open circuit.
2. CHECK BATTERY CABLE CONNECTION (VOLTAGE DROP TEST)
Check voltage between starter motor “B” terminal E313 terminal 2
(B) (VK45DE) or (B/R) (VQ35DE) and battery positive terminal.
OK or NG
OK >> GO TO 3.
NG >> Check harness between battery and 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.
OK or NG
OK >> “B” terminal circuit is OK. Further inspection necessary. Refer to SC-14, "
WORK FLOW" .
NG >> Check starter motor case and ground for poor continuity. VK45DE

DIAGNOSTIC PROCEDURE 2
Check “S” Connector Circuit
1. CHECK POWER SUPPLY FOR STARTER MOTOR “S” 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. Disconnect starter motor connector.
5. Check voltage between starter motor harness connector E312 (VK45DE) or F33 (VQ35DE) terminal 1 (B) and ground.
OK or NG
OK >> “S” connector circuit is OK. Further inspection neces- sary. Refer to SC-14, "
WORK FLOW" .
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)
Harness for open or short
