COMPONENT DIAGNOSIS

B TERMINAL CIRCUIT

Description

INFOID:0000000001728578

Terminal "2" (B) is constantly supplied with battery power.

Diagnosis Procedure

INFOID:0000000001728579

CAUTION:

Perform diagnosis under the condition that the 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 depleted.

1.

CHECK TERMINAL 2 POWER SUPPLY VOLTAGE

1.

Turn ignition switch OFF.

2.

Make sure that starter motor connector F27 terminal 2 connection is clean and tight.

3.

Check voltage between starter motor connector F27 terminal 2
and ground.

Is there battery voltage present?

YES

>> GO TO 2

NO

>> Check harness between battery and starter motor for

open circuit.

2.

CHECK BATTERY CABLE (VOLTAGE DROP TEST)

1.

Shift the transmission into park or neutral.

2.

Check voltage between battery positive terminal and starter
motor connector F27 terminal 2 while cranking the engine.

Is the voltage drop less than 0.2V?

YES

>> GO TO 3

NO

>> Check harness between the battery and the starter

motor for high resistance.

3.

CHECK GROUND CIRCUIT STATUS (VOLTAGE DROP TEST)

Check voltage between starter motor case and battery negative ter-
minal while cranking the engine.

Is the voltage drop less than 0.2V?

YES

>> Terminal 2 circuit is OK. Further inspection necessary.

Refer to 

STR-25, "Work Flow"

.

NO

>> Check the starter motor case to engine mounting for

high resistance.

S CONNECTOR CIRCUIT

Description

INFOID:0000000001728580

Terminal "1" (S) is the power supply for the starter motor magnetic switch. Terminal 1 is supplied with power
when the ignition switch is turned to the START position while the selector lever is in the P or N position.

Diagnosis Procedure

INFOID:0000000001728581

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 STARTER MOTOR MAGNETIC SWITCH CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect starter motor connector F28.

3.

Shift transmission into park or neutral.

4.

Check voltage between starter motor harness connector F28
terminal 1 and ground with the ignition in START.

Is battery voltage present?

YES

>> Magnetic switch circuit is OK. Further inspection necessary. Refer to 

STR-25, "Work Flow"

.

NO

>> GO TO 2

2.

CHECK CONNECTOR

1.

Turn ignition switch OFF.

2.

Check the IPDM E/R harness connector E44 and starter motor harness connector F28 for damage, bent
pins and loose connections.

Is the inspection result normal?

YES

>> GO TO 3

NO

>> Repair the terminal and connector.

3.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1.

Disconnect IPDM E/R connector E44 and starter motor connec-
tor F28.

2.

Check continuity between starter motor harness connector F28
(A) terminal 1 and IPDM E/R harness connector E44 (B) termi-
nal 19.

3.

Check continuity between starter motor harness connector F28
(A) terminal 1 and ground.

Are the continuity test results as specified?

YES

>> Further inspection necessary. Refer to 

STR-25, "Work Flow"

.

NO

>> Repair the harness.
