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.)

Start the engine, and warm it up to normal operat-
ing temperature (the radiator fan comes on twice).

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.

Road Test
NOTE: Warm up the engine to normal operating temperature (the radiator fan com6s on).
1. Apply the parking brake and block the wheels. Start the engine, then shift to the E position while depressing the
brake pedal. Depress the accelerator pedal and release it suddenly. The engine should not stall.
2. Test in E position
Park the vehicle in a slope (approx. 16'). apply the parking brake, and shift into E position. Release the brake; the
vehicle should not move.
3. Test-drive the vehicle on a flat road in the position shown in the table. Check that the engine speeds meet the approx-imate vehicle speeds shown in the table.
NOTE: Throttle position sensor voltage represents the throttle opening. To monitor the throttle position sensor volt-age, use one of the following methods:
A. Connect the Honda PGM Tester, and go to the PGM-FI Data List.
A1For road testing on '96 - 98 models, remove the drive/s side kick panel to expose the TCM; on '99 - OO models,remove the passenger's side kick panel to expose the PCM (see page l,[-236),
Set the digital multimeter to check throttle position sensor voltage between terminals:. '96 - 98 modols: TCM 84 {+} and Aa (-) or A17 (-1.. '99 - 0O models: FCM C27 {+l and 820 (-l ot 822 l-1.

Stall Speed
Test
CAUTION:
. To prevent transmission damage, do not test stall sp€€d for mole than 10 seconds at a time.
. Do not shift the lsver whils raising the engine speod.
. Be sure lo remove the pressure gauge before tosting stall speed.
. Stall speed tssts should be used tor diagnostic purposes only,
1. Engage the parking brake, and block the tront wheels.
2. Connect a tachometer to the engine, and stan the engine.
3. Make sure the A/C switch is OFF.
4. After the engine has warmed up to normal operating temperature (the radiator fan comes on), shift into E position.
5. Fully depress the brake pedal and accelerator for 6 to 8 seconds, and note engine speed,
6. Allow two minutes for cooling, then repeat the test in E, E, and E positions.

Fluid Level
l.Checking/Changing
CAUTION: while chscking and changing, be sure not to
allow dust and other toreign particles to ent€l inlo the
transmission.
Checking
NOTE: Check the fluid level with the engine at normal
operating temperature (the radiator fan comes on).
'1. Park the vehicle on the level ground. Turn oft the
engrne.
2. Remove the dipstick (yellow loop) from the trans-
mission, and wipe lt with a clean cloth.
NOTE: Check the transmission fluid 50 to 90 sec-
onds after shutting off the engine.
3. Insert the diDstick into the transmission.
DIPSTICK (YELLOW LOOPI
Remove the dipstick and check the fluid level.
should be between the uDDer and lower mark.DIPSTICK
5. lf the level is below the lower mark, add fluid into
the filler hole to bring it to the upper mark. Use
Genuine Honda CW Fluid only.
6. Insert the dipstick into the transmission.
14-299
Changing
1. Bring the transmission up to normal operating tem-
perature (the radiator fan comes on) by driving the
vehicle. Park the vehicle on the level ground, and
turn off the engine.
2. Bemove the drain plug, and drain the CVT fluid.
NOTE| lf a cooler flusher is to be used, see page 14-
352 and 14-353.
Reinstall the drain plug with a new sealing washer,
then refill the transmission with Genuine Honda
CVT Fluid to the upper mark on the dipstick.

Pressure Testing
. While testing, be careful of the rot8ling front wheels.
. M8k6 suro lifts, iacks, and satety stands are placed properly lsee section 11.
CAUTION:
. Before testing, be sur. the transmb3ion fluid is fillod to the propor lcvel.. Warm up the engin€ to nolmal operating tsmperature bofore testing. While t€sting, be 3ure not to allow dust and other loreign particles to onler into the transmi$ion.
1. Raise the front of the vehicle, and support it with safety stands (see section 1).
2. Set the parking brake. and block both rear wheels securely.
3. Allow the front wheels to rotate freely.
4. Warm up the engine (the radiator fan comes on), then stop arid connect a tachometer.
5. Connect the special tool to each inspection hole.
TOROUE: 18 N.m (1.8 kgt'm, 13 tbtfr)
GAUTION:
. Connect the oil pressuro gauge !!€curoly, bs sur6 not to allow dust and other foroign particlG3 to ontar the inspsc-tion hole.
. Whon troubleshooting by tho E indicltor light indic.t6 a problam. you mu3t u3e an oil p.essure gluge that moa,sures 4,9(X) kPa (a.90 MPa,50.0 kS cr*,771psi) or more when molsuring driv. pulley pressure and driven pullcypre33ure.
NOTE:
. D.ive pulley pressure may be above 3,430 kPa (3.i8 MPa,35.0 kgf/cmr, 498 psi) wh€n there is a transmission prob-
lem that causes the TCM or PCM to go into the fail-safe mode,. Use a commercially available oil pressure gauge that measures 4,900 kPa {4.90 MPa, 5O.O kgf/cmr, 711 psi) ormore, and the Ay'T Oil Pressure Hose, 2210 mm (07MAJ - PY4011A).
