Start Clutch Calibration Procedure
NOTE: When the following parts are replaced, the TCM
must memorize the feedback signal for the start clutch
control.
. TCM
. Transmissionassembly
. Stan clutch assembly
. Lower valve bodv assembly
. Engine assembly or overhaul
'96 Model Only
CAUTION: Do not uso this procsdure on'97 - (X) mod-
els or you will damage the transmission. On '97 - 00
models, the TCM or PCM memorizes ths loodback sig'
nals when you drive the vehicle.
1. Engage the parking brake, and block the front
wheels securely.
2. Connect the SCS service connector to the Service
Check Connector as shown. (The Service Check
connector (2P) is located under the dash on the
passenger's side of the vehicle.)
CONNECTOR07PAZ - lDl01(xt
Start the engine, and warm it up to normal operat-
ing temperature (the radiator fan comes on twice).
Fully depress the brake pedal and accelerator for 20
seconds in the E] position.

7.
Shift into E o|. E position. To store the engine
negative pressure in memory. Iet the engine idle in
E or E position for one minute under the follow-
ing conditions:
. With the brake pedal depressed,
. with the y'\/c switch oFF.
. With the combination light switch OFF.
. With the heater fan switch OFF.
. Turn OFF all other electrical systems
NOTE: Start step 5 within 60 seconds after the radi-
ator fan goes off.
Shift into E position, and let the engine idle for two
minutes to store the feedback signal in memory
under the same conditions as in step 5.
Connect the Honda PGM Tester. Check that the TCM
has completed the start clutch calibration.
NOTE:
. The TCM will not store the feedback signal when
the CVT fluid temperature is below 40"C (104'F)
even if the engine coolant temperature reaches
the normal operating temperature.
. Repeat these procedures until the start clutch
calibration is completed-
Disconnect the SCS service connector from the
Service Check Connector.
'97 - 00 Models
The TCM ('97 - 98 models) and PCM ('99 - 00 models)
memorize the feedback signal when you drive the
vehicle as follows:
. After warming up the engine (the radiator fan
comes onl.
. Shift into E position.
. Turn OFF all electrical systems,
. Drive the vehicle up to the speed 37 mph (60
km/h).
. After the speed reaches 37 mph (60 km/h),
release the accelerator for 5 seconds.

Removal
SRS components are located in this area Review the
SRS component locations, precautions, and procedures
in the SRS section (24) before performing repairs or ser-
vice.
NOTE: Before removing the steering wheel. align the
front wheels straight ahead.
1. Remove the driver's airbag assembly from the
steering wheel (see section 24)
2. Disconnect the horn connector and cruise control
switches connector.

3. Remove the steering wheel nut
STEERING WHEEL NUT
Replace.
Remove the steering wheel by rocking it slightly from
side-to-side as you pull steadily with both hands.

lnstallation
CAUTION: Do not tap on the steering wheel or steering
column shaft when installing the stsering wheel.
NOTE: Before installing the steering wheel, align the
front wheels straight ahead.
1. Before installing the steering wheel, center the
cable reel, Do this by first rotating the cable reel
clockwise until it stops. Then rotate it counterclock-
wise approximately two turns The arrow mark on
the cable reel label should points straight up.
Install the steering wheel with the steering wheel
nut.
NOTE: Be sure the steering wheel shaft engages
the cable reel and canceling sleeve.
Attach the cruise control switches connector io the
steering wheel cliP,
Connect the horn connector.
Install the driver's airbag assembly, and confirm
proper system operation (see section 24).
Check the horn and cruise control switches for
proper operatrons.

Brake Pedal
Pedal Height
1. Disconnect the brake switch connector, loosen the
brake switch locknut, and back off the brake switch
until it is no longer touching the brake pedal,
2. At the carpet cutout, measure the pedal height from
the right side center of the pedal pad.
PUSHRODLOCKNUT
Standard Pedal Height (with carpet removed):
M/T: 156.5 mm 16.16 inl
A/T, CVT: 161 mm (5 5/16 in)
3. Loosen the pushrod locknut, and screw the pushrod
in or out with pliers until the standard pedal height
from the floor is reached. After adjustment, tighten
the locknut firmly.
NOTE: Do not adiust the pedal height with the
Dushrod depressed.

4. Screw in the brake switch until its plunger is fully
depressed (threaded end touching the pad on the
pedal arm). Then back off the switch 1/4 turn to
make 0.3 mm (0.01 in) of clearance between the
threaded end and pad. Tighten the locknut firmly.
Connect the brake switch connector.
CAUTION: Make sure that the brake lights go off
when the pedal is released.

5. Check the brake pedal free play as described below.
Pedal Free Plsy
1. With the engine off, inspect the play on the pedal
pad by pushing the pedal by hand.
Free Play: 1 - 5 mm (1/16 - 3/16 inl
2. lf the pedal free play is out of specitication, adjust
the brake switch.
CAUTION: lf the pedal free play is insufficient, it
may result in brake drag.

ABS Control Unit
Main Control
The ABS control unit detects the wheel speed based on the wheel sensor signal it received, then it calculates the vehicle
speed based on the detected wheel speed. The control unit detects the vehicle speed during deceleration based on the
rate of deceleration.
The ABS control unit calculates the slip rate of each wheel. and it transmits the control signal to the modulator unit
solenoid valve when the slip rate is high.
The pressure reduction control is a three-mode system, that is pressure reduction, pressure retaining and pressure intensi-
fying modes.
Self -diagnosis Funqtion
The ABS control unit is equipped with a main CPU and a sub CPU, and the CPUS check each other'
The CPUs check the circuit of the svstem.
When the CPUS detect failure, they shift to the "system down mode" or the "control inhibition mode"
The self-diagnosis can be classifield into these four categories:
O: Initial diagnosis
@: Except ABS control
@: During ABS control
@: During warning
On-board Diagnosis Funstion
The ABS control unit is connected to the data link connector {16P).
The ABS system can be diagnosed with the Honda PGM Tester.
