B Terminal Circuit. Diagnosis Procedure. Diagnosis Procedure

Diagnosis Procedure

CAUTION:

Perform diagnosis under the condition that the engine cannot start by the following procedure:

1. CHECK “B” TERMINAL CIRCUIT

   1. 1. Ignition switch OFF.

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

      3. Check voltage between starter motor connector and ground.

         (+)		(-)	Voltage (Approx.)
         Starter motor
         Connector	Terminal
         F27	B	Ground	Battery voltage

   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. 1. Shift selector lever to P (Park) or N (Neutral) position (CVT Models) or the clutch pedal is depressed (M/T Models).

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

      (+)	(-)		Condition	Voltage (Approx.)
      	Starter motor
      	Connector	Terminal
      Battery positive terminal	F27	B	When the ignition switch is in START position	Less than 0.5 V

   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. 1. Shift selector lever to P (Pack) or N (Neutral) position (CVT Models) or the clutch pedal is depressed (M/T Models).

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

         (+)	(-)	Condition	Voltage (Approx.)
         Starter motor case	Battery negative terminal	When the ignition switch is in START position	Less than 0.2 V

   Is the inspection result normal?

   YES>>

   “B” terminal circuit is OK. Further inspection is necessary. Refer to Work Flow (With 165-DSS–5000P) or Work Flow (Without 165-DSS–5000P).

   NO>>

   Check the starter motor case to engine mounting for high resistance.

S Terminal Circuit. Description

Description

The starter motor magnetic switch is supplied with power when the ignition switch is placed to the START position while the selector lever is in the P (Park) or N (Neutral) position (CVT Models) or the clutch pedal is depressed (M/T Models).

Diagnosis Procedure

CAUTION:

Perform diagnosis under the condition that engine cannot start by the following procedure:

1. CHECK “S” CONNECTOR CIRCUIT

   1. 1. Ignition switch OFF.

      2. Disconnect starter motor connector.

      3. Shift selector lever to “P” (Park) or “N” (Neutral) position (CVT Models) or the clutch pedal is depressed (M/T Models).

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

         (+)		(-)	Condition	Voltage (Approx.)
         Starter motor
         Connector	Terminal
         F28	S	Ground	When the ignition switch is in START position	Battery voltage

   Is the inspection result normal?

   YES >>

   “S” circuit is OK. Further inspection is necessary. Refer to Work Flow (With 165-DSS–5000P) or Work Flow (Without 165-DSS–5000P).

   NO >>

   GO TO 2.

2. CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

   1. 1. Disconnect IPDM E/R connector.

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

         Starter motor		IPDM E/R		Continuity
         Connector	Terminal	Connector	Terminal
         F28	S	F97	83	Yes

      3. Check continuity between starter motor harness connector and ground.

         Starter motor		–	Continuity
         Connector	Terminal
         F28	S	Ground	No

   Is the inspection result normal?

   YES>>

   Further inspection is necessary. Refer to Work Flow (With 165-DSS–5000P) or Work Flow (Without 165-DSS–5000P).

   NO>>

   Repair or replace the harness or connectors.
