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.

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.
