3 Record the brinking frequency of the ABS indicator right. The brinking frequency indicates the DTc.
4, Turn the ignition switch OFF, and remove the SCS service connector.NorE: The Mslfunction Indicator Lamp (MlL) will stay on after the engine is started if the scs service connector isconnected.
5. Erase the DTC.

Connect the SCS service connector to the service check connector inside the passenger's side kick panel.
Depress the brake pedal.
Turn the ignition switch oN (ll) while holding the brake pedal, but do not start the engine. The ABS indicator light
goes off after two seconds.
After the indicator light goes off, release the brake pedal The indicator lightcomeson after four seconds

7. After four seconds, the indicator light blinks twice for 0 3 second and the DTC is erased
8. Confirm the DTC indication, and check that the DTC was erased
NOTE: Always maintain these steps. lf you disconnect the scs service connector and/or fail to operate the brake pedal
according to the indicator light indication, the DTC will not be erased
Conditions for DTC erasure
o The vehicle is stopped.

-Starter Test
NOTE; The air temoerature must be between 59 and
100'F (15 and 38"C) before testing.
Recommended Procedure:
. Use a staner system tester.
. Connect and operate the equipment in accordance
with the manufacturer's instructions.
. Test and troubleshoot as described,
Alternate Procedurg:
. Use the following equipment:- Ammeter, 0 - 400 A
- Voltmeter, 0 - 20 V (accurate within 0.1 volt)
- Tachometer, 0 - 1,200 rpm
. Hook up a voltmeter and ammeter as shown.
NEGATIVETERMINAL
NOTE: After this test, or any subsequent repair. reset
the ECM/PCM to clear any codes (see section l1)
Check the Start€r Engagemont:
1. Remove the No. 44 (15 A) fuse from the under-hood
fuse/relay box,
2. Turn the ignition switch to START (llll with the shift
lever in E or E position (rVT) or with the clutch pedal
depressed {M/T). The starter should crank the engine.
. lf the starter does not crank the engine, go to
step 3.
. lf itcranksthe engineerraticallyortooslowly, go
to "Check for Wear and Damage" on the next
page.
Check the battery. battery positive cable, ground,
starter cut relay, and the wire connections for loose-
ness and corrosion, Test again.
lf the starter still does not crank the engine, go to
step 4,
Unplug the connector (BLK,/WHT wire and solenoid
terminal) from the starter,
Connect a jumper wire from the battery positive (+)
terminal to the solenoid terminal.
The starter should crank the engine.
. lf the starter still does not crank the engine,
remove it, and diagnose its internal problem
. lf the startercranksthe engine, goto step 6.
Check the ignition switch (see page 23-891.
Check the starter cut relay and clutch interlock switch
(see page 23-86,87).
Check the A/f gear position switch (see page 23-154).
Check for an open in the wire between the ignition
switch and starter.

Starting System
Starter Test lcont'dl
Ch€ck tor Wear and Damage
The starter should crank the engine smoothly and
steadily, lf the starter engages. but cranks the engine
erratically, remove it, and inspect the starter drive gear
and torque converter or flywheel ring gear for damage.
. Check the drive gear overrunning clutch for binding
or slipping when the armature is rotated with the
drive gear held,- lf damaged. replace the gears.
Check Cranking Voltsge and Curr€nt Draw
Cranking voltage should be no less than 8.5 volts.
Current draw should be no more than 350 amperes.
lf cranking voltage is too low, or current draw too high,
check for;
. dead or low batterv.
. open circuit in starter armature commutator seg-
ments,
. starter armature dragging.
. shorted armature winding.
o excessive drag in engine.
Check Cranking rpm
Engine speed during cranking should be above 100 rpm,
lf speed is too low, check for:
. loose battery or stanerterminals.
. excessively worn starter brushes,
. open circuit in commutator segments.
o dirty or damaged helical spline or drive gear.
. defective drive gear overrunning clutch.
Check Siarter Disengag€ment
With the shift lever in El or @ position (A/T) or with the
clutch pedal depressed (M/T), turn the ignition switch to
START (lll), and release to ON (ll).
The starter drive gear should disengage from the torque
converter or flywheel ring gear when you release the
Key.
lf the drive gear hangs up on the torque converter or fly-
wheel ring gear, check for:
. solenoid plunger and switch malfunction,
. dirty drive gear assembly or damaged overrunning
clutch.
Starter Solenoid Test
1. Check the hold-in coil for continuitv between the S
terminal and the armature housing (ground). The
coil is OK if there is continuitv,

Interlock System
Control Unit Input Test
1. Disconnect the 8P connector from the interlock con-trol unit.
2. Inspect the connector and socket terminals to besure they are all making good contact.. lf the terminals are bent, loose or corroded, repairthem as necessary, and recheck the system.. lf the terminals look OK, make the followinginput tests at the connector.- lf a test indicates a problem, find and correctthe cause, then recheck the system.- lf all the input tests prove OK, substitute aknown-good control unit, and recheck the sys-tem. lf the check is OK, the control unit mustbe faulty; replace it.
NOTE: lf the shift lock solenoid clicks when theignition switch is turned ON {ll) and you step on thebrake pedal (with the shift lever in E), the shift locksystem is electronically normal; if the shift leve.cannot be shifted from E], test the Aff gear position
switch, park pin switch, and see section 14.
