S TERMINAL CIRCUIT

Description

INFOID:0000000006530934

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 or N position for CVT models or the clutch pedal is depressed for M/T
models.

Diagnosis Procedure

INFOID:0000000006530935

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” TERMINAL CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect starter motor connector.

3.

Shift selector lever to “P” or “N” position. (CVT models)
Keep depressing clutch pedal fully. (M/T models)

4.

Check voltage between starter motor harness connector and ground.

Is the inspection result normal?

YES

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

STR-14, "Work Flow"

.

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 IPDM E/R harness connector.

Is the inspection result normal?

YES

>> Further inspection is necessary. Refer to

STR-14, "Work Flow"

.

NO

>> Repair the harness.

INFOID:0000000006530939

INSPECTION

Magnetic Switch Check

• Before starting to check, disconnect the battery cable from the negative terminal.
• Disconnect “M” terminal of starter motor.
1.

Continuity test [between “S” terminal (A) and switch body]

• Replace magnetic switch if continuity does not exist.

2.

Continuity test [between “S” terminal (A) and “M” terminal (C)]

• Replace magnetic switch if continuity does not exist.

Pinion/Clutch Check

1.

Inspect pinion teeth.
• Replace pinion if teeth are worn or damaged. (Also check con-

dition of ring gear teeth.)

2.

Inspect reduction gear teeth (If equipped).
• Replace reduction gear if teeth are worn or damaged. (Also

check condition of armature shaft gear teeth.)

3.

Check to see if pinion locks in one direction and rotates
smoothly in the opposite direction.
• Replace pinion assembly if it is locked or rotated in both direc-

tions or unusual resistance is evident.

• Check wear of brush.

• Replace brush if the measurement value is less than the specified

value.

Brush Spring Check

• Check brush spring tension with brush spring detached from

brush.

• Replace brush spring if the measurement value is less than the

specified value.

Brush Holder Check

1.

Perform insulation test between brush holder (positive side) and
its base (negative side).
• Replace brush holder assembly if continuity does not exist.

2.

Check brush to see if it moves smoothly.
• If brush holder is bent, replace it; if sliding surface is dirty,

clean.

Yoke Check

Magnet is secured to yoke by bonding agent. Check magnet to see
that it is secured to yoke and for any cracks. Replace malfunctioning
parts as an assembly.

CAUTION:

Never clamp yoke in a vise or strike it with a hammer.

mm (0.008 in) or less.

ADJUSTMENT

Pinion Protrusion Length Adjustment

CLEARANCE

• With pinion driven out by magnetic switch, push pinion back to

remove slack and measure clearance “L” between the front edge
of the pinion and the pinion stopper.

• Adjust with the adjusting plate if the measurement value is not in
