Troubleshooting Procedures
1.
2.
(cont'dl
Remove the kick panel on the passenger's side {see section 20}.
Remove the PCM. and turn the PCM over.
Inspect the circuit on the PCM according to the troubleshooting flowchart with the spocial tools and a digital multime-ter as shown.
How lo Use tha Backprobe Set
Connect the backprobe adapters to the stacking patch cords, and connect the cords to a multimeter. Using the wireinsulation as a guide for the contoured tip of the backprobe adapter, gently slide the tip into the connector from thewire side until it comes in contact with the terminal end ofthe wire.

Road Test
NOTE: Warm up the engine to normal operating tem peratu re (the rad iator fan comes on )'
1. Apply parking brake and block the wheels. Start the engine, then shift to E position while depressing the brake
Dedal, Depress the accelerator pedal and release it suddenly. The engine should not stall'
2. Repeat same test in E Position.
3. Test-drive the vehicle on a flat road in the E position. Check that the shift points occur at approximate speeds shown
in the table. Also check for abnormal noise and clutch slippage.
NOTE: Throttle position sensor voltage represents the throttle opening
a. Unbolt the PCM for road testing; refer to page 14-50.
b. Setthedigital multimeter to check the th rottle position sensor voltage between PCM terminals;

Electronic Gontrol System ('99 - 00 Modelsl
The electronic controt system conststs of a Powertrain control Module (PCM). sensors, three linear solenoids and an
inhibitor solenoid. shifting is electronically controlled under all conditions A Grade Logic control system to control shift-
ing in E position while the vehicle is ascending or descending a slope'
fn"pCVirlocatedbelowthedashboard,underthekickpanelonthepassenger'sside'
The pCM controls the transmassion to reduce engine speed and retain the engine's cooling efficiency when the vehicle is
driven with full throftle acceleration
lf the vehicle is continuously driven at lull throttle acceleration, the PCM regulates the pulley hydraulic pressure to
increase the pulley ratio which. as the result, reduces the engine speed and retains the designed cooling efficiency After
the vehicle has been driven at a lower engine speed for a while, the PCM increases the pulley ratio to the original ratio'
i"i ".nl",rr starting in the E position, the PcM cuts off the ,Vc clutch (if the A/c is on) and increases the engine speed to
900 rpm when the transmission is shifted to the E position'
The start clutch functions to make smooth starting possible. To let the start clutch function properly, the PcM regulates
the start clutch hydraulic pressure based on the engine's negative pressure memorized in the E position'

Troubleshooting Procedures
(cont'd)
C. lf the inspection for a particular code requires voltage or resistance checks at the TCM or PCM connectors, removethe driver's side kick panel, and unbolt the TCM, and at the PCM connectors, remove the passenger's side kickpanel, and unbolt the PCM. Turn the ignition switch OFF, and connect the backprobe sets and a digital multimeteras described below. Check the system according to the procedure described for the appropriate code(s) listed onthe following pages.

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.

Inspection
NOTE: The tilt steering column type is shown; the con-

Check the steering column ball bearing and the steer-ing joint bearings for play and proper movement. lf
there is noise or if there is excessive play, replace the
steering column as an assembly.
Check the retaining collar for damage. lf it is dam-
aged, replace the retaining collar.
Check the absorbing plates, absorbing plate
and sliding capsules for distonion or breakage.

1.Move the tilt lever from the loose position to lockposition 3 to 5 times; then measure the tilt leverpreload l0 mm {0.4 in) from the end ofthe tilt lever.
Preload: 70 - 90 N (7 - 9 kgf. 15 - 20 lbf)
lf the measurement is out of the specification,
adjust the pfeload using the following procedures.
a. Loosen the tilt lever, and set the steering column
in the neutral position.
b. Remove the 6 mm lock bolt and remove the stop.
c. Adjust the preload by turning the tilt lock bolt left
or flgnr.
d. Pull up the tilt lever to the uppermost position and
install the stop. Check the preload again. lf the
measurement is still out of specification, repeat
the above procedures "a" through "c" to adjust.
CAUTION: Be caretul not to loosen tho tilt lever
when installing the stop or tightening the 6 mm
lock bolt.
