S Connector Circuit

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 (CVT models) or the clutch pedal is fully depressed (M/T models).




Diagnosis Procedure
Regarding Wiring Diagram information, Starting System Coupe or Starting System Sedan, "Wiring Diagram - Sedan With QR25DE".

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. (CVT models)
Press and hold the clutch pedal fully with the control lever in neutral. (M/T models)
4. Check voltage between starter motor harness connector F28 terminal S and ground with the ignition in START.





Is battery voltage present?
YES - "S" circuit is OK. Further inspection 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 IPDM E/R connector F10.
2. Check continuity between starter motor harness connector F28 terminal S and IPDM E/R harness connector F10 terminal 80.

S - 80 Continuity exists

3. Check continuity between starter motor harness connector F28 terminal S and ground.

S - ground Continuity does not exist

Are the continuity test results as specified?
YES - Further inspection necessary. Initial Inspection and Diagnostic Overview.
NO - Repair the harness.
