SC-12
STARTING SYSTEM
Revision: 2007 April2007 M35/M45
DIAGNOSTIC PROCEDURE 1
Check “B” Terminal Circuit
CAUTION:
Perform diagnosis under the condition that engine cannot start by the following procedure.
1. Remove fuel pump fuse.
2. Crank or start the engine (where possible) until the fuel pressure is released.
1. CHECK “B” TERMINAL CIRCUIT
1. Turn ignition switch OFF.
2. Make sure that starter motor “B” terminal connection is clean
and tight.
3. Check voltage between starter motor “B” terminal 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 STATUS (VOLTAGE DROP TEST)
Check voltage between starter motor “B” terminal and battery posi-
tive terminal.
OK or NG
OK >> GO TO 3.
NG >> Check harness between the battery and the starter motor for poor continuity.
*1 For battery testing, use Battery Ser-
vice Center (J-48087). For details
and operating instructions, refer to
Technical Service Bulletin and/or
Battery Service Center User Guide.*2SC-13, "MINIMUM SPECIFICATION
OF CRANKING VOLTAGE REFER-

3. CHECK GROUND CIRCUIT STATUS (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-11, "
Trouble Diagnosis with Starting/Charging System Tester (Starting)" .
NG >> Check the starter motor case and ground for poor continuity.
DIAGNOSTIC PROCEDURE 2
Check “S” Connector Circuit
CAUTION:
Perform diagnosis under the condition that engine cannot start by the following procedure.
1. Remove fuel pump fuse.
2. Crank or start the engine (where possible) until the fuel pressure is released.
1. CHECK “S” CONNECTOR CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect starter motor connector.
3. Check voltage between starter motor harness connector and
ground.
OK or NG
OK >> “S” connector circuit is OK. Further inspection necessary. Refer to SC-11, "Trouble Diagnosis with
Starting/Charging System Tester (Starting)" .
NG >> Check the following.
