A: REMOVAL AND INSTALLATION
CAUTION:
IIf the side of the vehicle body is damaged by
a collision, be sure to check the left and right
side airbag sensors, even if the airbag was not
inflated. If any damage to the sensor or any
deformation of the sensor mount is found,
replace with a new genuine part.
IWhen painting or performing sheet metal
work on the side part of vehicle body, including
the side sill, center pillar, front and rear doors,
take utmost care not to apply dryer heat, paint-
ing mist, or the flame of the welding burner
directly to the side airbag sensors and wire
harness of the airbag system.
1) Turn ignition switch off.
2) Disconnect ground cable from battery and wait
for at least 20 seconds before starting work.
3) Remove center pillar lower. [W5A2].>

B: TEST
1. MAGNETIC SWITCH
CAUTION:
IThe following magnetic switch tests should
be performed with specified voltage applied.
IEach test should be conducted within 3 to 5
seconds. Power to be furnished should be one-
half the rated voltage.
1) Pull-in test
Connect two battery negative leads onto magnetic
switch body and terminal C respectively. Then con-
nect battery positive lead onto terminal 50. Pinion
should extend when lead connections are made.
B6M0415A
2) Holding-in test
Disconnect lead from terminal C with pinion
extended. Pinion should be held in the extended
position.
B6M0416A
3) Return test
Connect two battery negative leads onto terminal
50 and onto switch body respectively. Then con-
nect battery positive lead onto terminal C. Next,
disconnect lead from terminal 50. Pinion should
return immediately.
B6M0417A
2. PERFORMANCE TEST
The starter is required to produce a large torque
and high rotating speed, but these starter charac-
teristics vary with the capacity of the battery. It is
therefore important to use a battery with the speci-
fied capacity whenever testing the starter.
The starter should be checked for the following
three items:
INo-load test
Measure the maximum rotating speed and current
under a no-load state.
ILoad test
Measure the magnitude of current needed to gen-
erate the specified torque and rotating speed.
IStall test
Measure the torque and current when the armature
is locked.

6-1[W1B1]SERVICE PROCEDURE
1. Starter

1) No-load test
Run single starter under no-load state, and mea-
sure its rotating speed, voltage, and current, using
the specified battery. Measured values must meet
the following standards:
No-load test (Standard):
Voltage/Current
11 V/90 A, or more
Rotating speed
TN128000-8311: 3,000 rpm, or more
TN128000-8321: 3,350 rpm, or more
B6M0418A
2) Load test (For reference)
Perform this test to check maximum output of
starter. Use test bench which is able to apply load
(brake) to starter. Measure torque value and rotat-
ing speed under the specified voltage and current
conditions while controlling braking force applied to
starter.
CAUTION:
Change engagement position of overrunning
clutch and make sure it is not slipping.
Load test (Standard):
TN128000-8311
Voltage/Load
8 V/9.8 N´m (1.0 kg-m, 7.2 ft-lb)
Current/Speed
280 A max./900 rpm min.
TN128000-8321
Voltage/Load
8 V/13.7 N´m (1.4 kg-m, 10.1 ft-lb)
Current/Speed
370 A, or less/880 rpm, or more
B6M0419A
3) Stall test
Using the same test equipment used for load test,
apply brake to lock starter armature. Then mea-
sure voltage, current, and torque values.
Measured values must meet the following stan-
dard.
Stall test (Standard):
TN128000-8311
Voltage/Current
5 V/800 A, or less
Torque
27.5 N´m (2.8 kg-m, 20.3 ft-lb) min.
TN128000-8321
Voltage/Current
5 V/1,050 A, or less
Torque
27.5 N´m (2.8 kg-m, 20.3 ft-lb) min.
B6M0420A
NOTE:
Low rotating speed or excessive current during no-
load test may be attributable to high rotating resis-
tance of starter due to improper assembling.
Small current and no torque during stall test may
be attributable to excessive contact resistance
between brush and commutator; whereas, normal
current and insufficient torque may be attributable
to shorted commutator or poor insulation.
Starter can be considered normal if it passes no-
load and stall tests; therefore, load test may be
omitted.
C: DISASSEMBLY
1) Disconnect lead wire from magnetic switch.
