         Celica

    DESCRIPTION
         Celica uses a Nippondenso 4-brush, solenoid-actuated, gear
reduction-type starter, equipped with an overrunning clutch. The brush
holder assembly retains 4 brushes and springs in the starter housing.
         Reduction gear type starters contain an integral solenoid
attached to drive housing, a reduction idler gear and bearing
installed into starter housing, and a clutch drive assembly. The
clutch drive assembly is mounted to starter housing and is driven by
the reduction idler gear from armature shaft. The brush holder
assembly retains 4 brushes and 4 springs in the end cover of field
frame housing.
         Manual transmission vehicles use a clutch start switch and
automatic transmission vehicles use a park/neutral switch to energize
starter relay. On models with theft deterrent system, theft deterrent
system ECU provides ground for starter relay.

NOTE:   Starter type and kilowatt (kW) rating can be found on a
        metal label attached to side of starter.

    TROUBLE SHOOTING
         1) If a no-start condition exists and battery is known to be
good, connect test light or voltmeter between starter solenoid
terminal No. 50 and ground. See Fig. 8.
         2) Turn ignition switch to START position. If test light or
voltmeter does not indicate voltage, check main fusible links and
large ampere main fuses in engine compartment relay box. If fusible
links and fuses are okay, see IGNITION SWITCH CONTINUITY TEST and/or
STARTER RELAY TEST under ON-VEHICLE TESTING.

    ON-VEHICLE TESTING
NOTE:   Before testing, ensure battery is fully charged, battery
        cables and terminal ends are tight and clean, and engine
        grounds are secure.

    CLUTCH START SWITCH TEST
         1) Switch is located above clutch pedal on bracket.
Disconnect wiring harness connector from switch.
         2) Connect ohmmeter probes to switch terminals. Depress
clutch pedal. If continuity does not exist, adjust or replace clutch
start switch. If continuity exists, check circuit to starter relay for
open, and check starter relay. See STARTER RELAY TEST.

         1) Disconnect negative battery cable. Remove driver's lower
instrument panel cover. Remove upper and lower steering column covers
if needed. Locate ignition switch wiring harness 10-pin connector. See
Fig. 2.
         2) With ignition switch in LOCK position, there should be no
continuity between any terminals. With ignition switch in ACC
position, there should be continuity between terminals No. 3 and 4.
With ignition switch in ON position, there should be continuity
between terminals No. 2, 3 and 4, and between terminals No. 9 and 10.
With ignition switch in START position, there should be continuity
between terminals No. 2, 4 and 7, and between terminals No. 6, 9 and
10. If continuity is not as specified, replace switch.

    PARK/NEUTRAL SWITCH
NOTE:            If vehicle will not start with shift lever in Park/Neutral
                 position, verify correct park/neutral switch adjustment. If
                 park/neutral switch is correctly adjusted, verify switch
                 continuity.

         Adjusting Park/Neutral Switch
         Locate park/neutral switch at transmission or transaxle.
Loosen park/neutral position switch bolt(s) and verify shift selector
is in "N" position. Align switch shaft groove with neutral basic line
on switch. Hold switch in position and tighten switch bolt(s) to 48
INCH lbs. (5.4 N.m).

         Park/Neutral Switch Continuity Check
         Disconnect electrical connector from park/neutral switch at
transmission or transaxle. Using ohmmeter, check for continuity at
specified terminals with gearshift in proper positions. See Figs. 3
and 4. See PARK/NEUTRAL SWITCH CONTINUITY table. Replace switch if
defective.
