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, Coupe or Sedan.

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 F81 (CVT models).
Disconnect starter motor connector F82 (coupe with M/T models).
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 F81
(CVT models) or F82 (coupe with M/T models) 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 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 F81 (CVT models)
-Starter motor harness connector F82 (coupe with M/T models)
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 F81 (CVT models) or F82 (coupe with M/T models) terminal S and IPDM E/R harness connector F10 terminal 80.
S - 80Continuity exists
3.Check continuity between IPDM E/R harness connector F10 terminal 80 and ground.
.
80 - 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.
