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.

3. Disconnect the air mix control cable, and remove the
screws, then pull out the center panel.
4. Disconnect the connectors from the heater control
u nit.
5. Installation is the reverse of the removal procedure.
NOTE:
. Make sure the connectors are connected properly.
. Adjust the air mix control cable (see section 21).

Removal
SRS components are located in this area. Review the
SRS component locations, precautions, and procedures
in the SRS section (24) before preforming repairs or ser-
vice.
NOTE:
. An assistant is helpful when removing and installing
the dashboard.
. Take care not to scratch the dashboard, body and
related parts.
1. Remove:
o Front and rear consoles (see page 20-67)
. Console panel (see page 2O 67),
. Driver's dashboard lower cover and knee bolster(see page 20-68)
. Glove box (see page 20-69)
. Center dashboard lower cover (see page 20-69i
2. Lower the steering column (see section 17).
@ To avoid accidental deplovment and
possible injury, always disconnect the driver's
airbag connector belore lowering the steering col-
umn lsee section 241.
NOTE: To prevent damage to the steering column,
wrap it with a shop towel.
3. Disconnect the dashboard wire harness connectors,
remove the nuts, then move the under-dash fuse/
relay box. Disconnect the antenna lead and moon-
roof relay connectors.
