S CONNECTOR CIRCUIT

Description

The starter motor magnetic switch 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

Regarding Wiring Diagram information, [1][2]Electrical Diagrams.

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 F28.
3.Shift CVT selector lever to "P" or "N" position.
4.Check voltage between starter motor harness connector F28
terminal S and ground with the ignition in START.
With ignition switch in START
S - ground Battery voltage
Is battery voltage present?
YES- "S" circuit is OK. Further inspection is necessary. Initial Inspection and Diagnostic Overview.
NO- GO TO 2

2. CHECK CONNECTOR

1.Turn ignition switch OFF.
2.Check the following terminals and connectors for damage, bent pins and loose connections.
-IPDM E/R harness connector F10
-Starter motor harness connector F28
Is the inspection result normal?
YES- GO TO 3
NO- Repair the terminal and connector.

3. CHECK HARNESS CONTINUITY (OPEN/SHORT CIRCUIT)






1.Disconnect the following harness connectors.
-IPDM E/R connector F10
-Starter motor connector F28
2.Check continuity between starter motor harness connector F28
terminal S and IPDM E/R harness connector F10 terminal 80.
S - 80Continuity exists
Is the inspection result normal?
YES- Further inspection is necessary. Initial Inspection and Diagnostic Overview.
NO- Repair the harness.
