<> SNAP RING AND STOP RING REMOVAL
1. Press a long socket wrench of appropriate size to the stop
ring. Then tap the socket wrench to remove the stop ring to
the pinion gear side.
2. After removing the snap ring (by using snap-ring pliers),
remove the stop ring and the overrunning clutch.
STARTER MOTOR PART CLEANING
1. Do not immerse parts in cleaning solvent. Immersing the
yoke and field coil assembly and/or armature will damage
insulation. Wipe these parts with a shop towel only.
2. Do not immerse the drive unit in cleaning solvent.
Overrunning clutch is pre-lubricated at the factory and
solvent will wash lubrication from the clutch.
3. The drive unit may be cleaned with a brush moistened with
cleaning solvent and wiped dry with a shop towel.

INSPECTIONM1162001300102.
COMMUTATOR CHECK
1. Place the armature on a pair of V-blocks, and check the
deflection by using a dial gauge.
Standard value: 0.05 mm (0.002 inch)
Limit: 0.1 mm (0.004 inch)
2. Check the outer diameter of the commutator.
Standard value: 29.4 mm (1.16 inches)
Minimum limit: 28.8 mm (1.13 inches)
3. Check the depth of the undercut between segments.
Standard value: 0.5 mm (0.02 inch)
Minimum limit: 0.2 mm (0.008 inch)
.
BRUSH CHECK
1. Check the brush for roughness of the surface that contacts
the commutator and check the brush length. Replace the
brush holder if this measurement exceeds the limit.
Minimum limit:
7.0 mm (0.28 inch)
2. If the contacting surface has been corrected or the brush
has been replaced, correct the contacting surface by
winding sandpaper around the commutator.

OVERRUNNING CLUTCH CHECK
1. While holding the clutch housing, rotate the pinion. The drive
pinion should rotate smoothly in one direction, but should
not rotate in the opposite direction. If the clutch does not
function properly, replace the overrunning clutch assembly.
2. Inspect the pinion for wear or burrs. If the pinion is worn or
burred, replace the overrunning clutch assembly. If the
pinion is damaged, also inspect the ring gear for wear or
burrs.
.
FRONT AND REAR BRACKET BUSHING CHECK
Inspect the bushing for wear or burrs. If the bushing is worn or
burred, replace the front bracket assembly or rear bracket
assembly.
.
ARMATURE CHECK
1. Check that the armature coil is not grounded.
2. Place the armature in a growler.
3. Hold a thin steel blade parallel and just above while rotating
the armature slowly in the growler. A shorted armature will
cause a blade to vibrate and be attracted to the core.
Replace the shorted armature.
4. Check the insulation between the armature coil cores and
the commutator segments. They are normal if there is no
continuity.
5. Check for continuity between the segments. The condition is
normal if there is continuity.

the power windows operate properly. If they don't, then
troubleshoot as described in GROUP 54B, SWS Diagnosis
P.54B-57.
2. Turn ON the power window lock switch of the power window
main switch. Then operate the passenger's door and rear
door power window sub-switches to ensure that they do not
operate. If they do, replace the power window main switch
(Refer to P.42-39).
CENTRAL DOOR LOCKING SYSTEM
INSPECTION

Check the following. Troubleshoot if operations malfunction
(Refer to GROUP 54B, SWS Diagnosis P.54B-57).
Insert the key into the driver's key cylinder and turn once to
the unlock side to unlock the driver's door and fuel lid door.
Turn the key once again to the unlock side to unlock all
doors and fuel lid door.
All doors and fuel lid door can be locked using the door lock
switch built into the front power window (main or sub )
switch.

BASIC BRAKE SYSTEM DIAGNOSIS
BASIC BRAKE SYSTEM35A-4
STEP 2. Check disc brake pistons for smooth
operation.
(1) With engine not running, depress the brake pedal
rapidly several times to deplete booster vacuum
reserves.
(2) Test each disc brake assembly one at a time.
a. Remove the lower caliper bolt, then remove
caliper from mount.
b. Have an assistant slowly depress the brake
pedal. Confirm piston(s) extend slowly and
smoothly with no jumpiness. Repeat for each
disc brake assembly.
Q: Do (does) the piston(s) move correctly?
YES :
Go to Step 3.
NO : Disassemble and inspect the brake
assembly (Front: refer to P.35A-33, Rear:
refer to P.35A-36). Then go to Step 5.
STEP 3. Check brake disc(s) for runout.
Refer to P.35A-19.
Q: Is runout outside of specifications?
YES :
Repair or replace the brake disc(s) as
necessary. Then go to Step 5.
NO : Go to Step 4.
STEP 4. Check brake discs for correct thickness.
Refer to P.35A-19.
Q: Is the thickness outside of specifications?
YES :
Repair or replace the brake disc(s) as
necessary. Then go to Step 5.
NO : Perform the brake line bleeding. Then go to
St e p 5.
STEP 5. Retest the system.
Q: Is the symptom eliminated?
YES :
The procedure is complete.
NO : Start over at Step 1. If a new symptom
appears, refer to the appropriate symptom
chart.

.
DIAGNOSIS
STEP 1. Check that the specified brake fluid is
used, its level is correct, and no contamination is
found.
Q: Is there a fault?

brake pedal slowly until it stops.
(3) With a measuring device (ruler, etc.) next to the
brake pedal, depress the pedal firmly and
measure the distance the pedal traveled.
Q: Is the distance greater than 20 mm (0.8 inch)?
YES :
Bleed the brakes to remove air in the fluid
(Refer to P.35A-16). Then go to Step 7.
NO : Go to Step 3.
STEP 3. Check the brake booster function.
Refer to P.35A-14.
Q: Is there a fault?
