STARTER INSPECTION[L3 WITH TC]
On-vehicle Inspection
1. Verify that the battery is fully charged.
2. The starter is normal if it rotates smoothly and without any noise when the engine is cranked.
• If the starter does not operate, inspect the following:
— Remove the starter, and inspect the starter unit.
— Inspect the related wiring harnesses, the ignition switch, and the transaxle range switch.
No-load Test
1. Verify that the battery is fully charged.
2. Connect the starter, battery, and a tester as
shown in the figure.
3. Operate the starter and verify that it rotates
smoothly.
• If the starter does not rotate smoothly, inspect
the starter unit.
4. Measure the voltage and current while the starter
is operating.
• If not within the specification, replace the
starter.
Starter no-load test voltage
11 V
Starter no-load test current
90 A or less
Magnetic Switch Operation Inspection
Pull-out test
Note
• Depending on the battery charge condition, the starter motor pinion may rotate while in an extended state.
This is due to current flowing to the starter motor through the pull-in coil to turn the starter motor, and does
not indicate an abnormality.
1. Verify that the starter motor pinion is extended
while battery positive voltage is connected to
terminal S and the starter body is grounded.
• If the starter motor pinion is not extended,
repair or replace the starter.
