Starting System
Starter Test (cont'dl
Check Cranking rpmr
Engine speed during cranking should be above 1OO rpm.
lJ speed is too low, check for:
a Loose batlery or starter terminals
a Excessively worn starter brushes
a Open circuit in commutator segments
a Dirty or damaged helical spline or drive gear
a Defective drive gear overrunning clutch
Check Starter Disengagement:
Press the clutch pedal all the way in (M/T), turn rhe igni
tion switch to "lll" and release to "11".
The starter drive gear should disengage from the flywheel
or torque converter ring gear when you release the key.
It the drive gear hangs up on the flywheel or torque con-
verter ring gear, check for:
a Solenoid plunger and switch mallunction
a Dirty drive gear assembly or damaged overrunning
clutch
5. Check for an open in the BLK/WHT wire circuit be
tween the starter and ignition switch, and con-
necrors,
6. Check the ignition switch (see page 23-71).
7. On cars with automatic transmission, check the A/Tgear position switch (neutral position switch) and
connector. On cars with manualtransmission, check
the starter cut relay, clutch interlock switch, and
connectors.
NOTE: Check the No. 42 (40 A) fuse in the under,hoodfuse/relay box for the starter cut relay.
Check Jor Wear and Damage:
The starter should crank the engine smoothly and stead,ily. lf the starter engages, but cranks the engine errati
cally, remove it. Inspect the starter, drive gear, andllywheel or torque converter ring gear lor damage.
a Check the drive gear overrunning clutch for binding
or slipping when the armature is rotated with the drivegear held. Replace the gears i{ damaged.
Check CJanking Voltage and Current Draw:
Cranking voltage should be no less than 8.O volts.
Current draw should be no more than * amperes.* 1.2 kW: 27O A
1 .4 kW: 360 A
It cranking voltage is too low, or current draw too high,check for:
a Dead or low charged batterya Open circuit in starter armature commutator segmentsa Starter armalure dragging
a Shorted armature windinga Excessive drag in engine

Control Unit Input Test
1. Disconnect the 8P connector from the interlock con-
trol unit.
2. lnspect the connector and socket terminals to be
sure they are all making good contact.
a It the terminals are bent, loose or corroded, repair
them as necessary, and recheck the system.
a lf the terminals look OK, make the following in-
put tests at the connector.- lf a test indicates a problem, tind and correct
the cause, then recheck the system.- lf all the input tests prove OK, substitute a
known-good control unit, and recheck the sys-
tem. lf the check is OK, the control unit must
be faulty; replace it.
NOTE: lf the shift lock solenoid clicks when the igni-
tion switch is turned ON (ll) and you step on the
brske Dedal (with the shift lever in E). the shift lock
system is electronically normal; if the shift lever
cannot be shifted from fl, test the 46 gear position
switch as described on page 23-142, and see sec-
tion 14.

Precautions/Procedures
Steering-related Precautions
Steering Wheel and Gable Reel Alignment
NOTE: To avoid misalignment of the steering wheel or
airbag on reassembly. make sure the wheels are turned
straight ahead before removing the steering wheel.
Rotate the cable reel clockwise unit it stops.
Then rotate it counterclockwise (approximately two and a
half turns) until the arrow mark on the cable reel label
points straight up.
ARROW MARK
23-286
Steering Column Removal
CAUTION:
. Before romoving the steoring column, lirst di3con-
nect ths connector bctwoen tho csble rsal and the
SBS main harneEs.
. lf the steeting column is going to be rsmoved with-
out dismounting the steering wheel, lock the steer-
ing by iurning the ignition k6y to o'LOCK position' or
remove tho key lrom thc ignition ro that the steering
wheel will not turn.
NOTE:
When the airbag and cable reel are disconnected, and
the battery is reconnected and the ignition switch is
turned ON (ll), the SRS unit will store this as an open
in the driver's airbag inflator, and the SRS indicator
light will come on. In such a case, make sure to con-
firm the DTC, then clear the SRS unit memory.
For disconnecting the spring-loaded lock type connec-
tor, refer to page 23-284,
SRS MAIN HARNESS2P CONNECTOR
Do not replace the original steering wheel with any other
design since it will make it impossible to properly install
the airbag {only use genuine Honda replacement parts).
After reassembly. confirm that the wheels are still turned
straight ahead and that the steering wheel spoke angle is
correct, lf minor spoke angle adjustment is necessary, do
so only by adjusting the tie-rods, not by removing and
repositioning the steering wheel.
