DTC/CIRCUIT DIAGNOSIS

B TERMINAL CIRCUIT

Description

INFOID:0000000009446823

Terminal “B” is constantly supplied with battery power.

Diagnosis Procedure

INFOID:0000000009446824

Regarding Wiring Diagram information, refer to 

STR-7, "Wiring Diagram"

.

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 released.

1.

CHECK “B” TERMINAL CIRCUIT

1. Turn ignition switch OFF.

2. Check that starter motor ”B” terminal connection is clean and tight.

3. Check voltage between starter motor ”B” terminal and ground.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Check harness between battery and starter motor for open circuit.

2.

CHECK BATTERY CABLE CONNECTION STATUS (VOLTAGE DROP TEST)

1. Shift selector lever to ”P” (Park) or ”N” (Neutral) position.

2. Check voltage between battery positive terminal and starter motor ”B” terminal.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Check harness between the battery and starter motor for continuity.

3.

CHECK GROUND CIRCUIT STATUS (VOLTAGE DROP TEST)

1. Shift selector lever to ”P” (Park) or ”N” (Neutral) position.

2. Check voltage between starter motor case and battery negative terminal.

Is the inspection result normal?

Description

INFOID:0000000009446825

The starter motor magnetic switch is supplied with power when the ignition switch is turned to the START posi-

tion while the selector lever is in the P (Park) or N (Neutral) position.

Diagnosis Procedure

INFOID:0000000009446826

Regarding Wiring Diagram information, refer to 

STR-7, "Wiring Diagram"

.

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. Shift selector lever to “P” (Park) or “N” (Neutral) position.

4. Check voltage between starter motor harness connector and ground.

Is the inspection result normal?

YES

>> “S” circuit is OK. Further inspection is necessary. Refer to 

STR-13, "Work Flow (With GR8-1200

NI)"

 or 

STR-16, "Work Flow (Without GR8-1200 NI)"

.

NO

>> GO TO 2.

2.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT) 

1. Disconnect IPDM E/R connector.

2. Check continuity between starter motor harness connector and the IPDM E/R harness connector.

3. Check continuity between starter motor terminal S and ground. 

Is the inspection result normal?

YES

>> Further inspection is necessary. Refer to 

STR-13, "Work Flow (With GR8-1200 NI)"

 or
