Interlock System
Interlock Control Unit Input Test
SRS components are located in this area. Review the SRS component locations, precautions, and procedures in the SRS
section (24) before performing repairs or service.
'1. Remove the instrument panel lower cover (see section 20).
2. Disconnect the 8P connector from the interlock control unit.
3. Inspect the connector and connector terminals to be sure they are all making good contact.
. lf the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system
. lf the terminals look OK, make the following input tests at the connector.
- lf a test indicates a problem, find and correct the cause, then recheck the system
- lf all the input tests prove OK, substitute a known-good control unit, and recheck the system. lf the check is OK,
the control unit must be faulty; replace it.
NOTE: lf the shift lock solenoid clicks when the ign ition switch is tu rned ON (ll) while pressing the brake pedal withthe
shift lever in E position, the shift lock system is OK. lf the shift lever cannot be shifted from E position. test the A/T
gear position switch.

Road Test
NOTE: Warm up the engine to normal operating temperature (the radiator tan comes on).
1. Before testing, check the transmission fluid level, see page 14-160.
2. Apply the parking brake and block the wheels. start the engine, then shift to E {'97 - 98) or E {'gg - 00) position
while pressing the brake pedal. Press the accelerator pedal and release it suddenly. The engine should not stall.
3. Repeat same test in E position ('97 - 98 models).
4. Test-drive the vehicle on a flat road in the E or E position. Check that the shift points occur at approximate speeds
shown on a flat road. Also check for abnormal noise and clutch slippage.
Throttle position sensor voltage represents the throttle opening. Monitor it with the Honda PGM Tester or as follows:
a. Unbolt the PCM for road testing; reJer to page 14-58.
b. Set the digital multimeter to check throttle position sensor voltage between these terminals on the PCM:
. '97 Model: Between terminals D'! (+) and A9 (-) or A22 {-}
. '98 - OO Models; Between terminals C27 (+) and 820 (-) or 822 {-)

Stall Speed
Test
CAUTION:
. To prevent transmission damage, do not te3t stall speed for mors than 10 s€€onds at a time'
. Do not shift the lever while raising th€ engine spsed.
. Be sure to remove tho pressuro gauge bofore testing stall speed,
1. Before testing, check the transmission fluid level, s€e page 14-160.
2. Engage the parking brake and block all four wheels
3. Connect the tachometer, and start the engane.
4. Make sure the Ay'C switch is OFF
5. After the engine haswarmed upto normal operating temperature (the radiator fan comes on),shiftinto@ position.
6. Fully press the brake pedal and accelerator for 6 to 8 seconds, and note engine speed '
j. A|ow 2 minutes for cooling, then repeat the test in E, E ('97 - 98). E {'99 - 00}, and E positions. Stall speed should
be the same in E, E, E, tr. and E positions

Inspection and Adjustment
Brake System Rubber Parts and Brake Booster
@-Brake Booster
Check brake operation by applying the brakes.
lf the brakes do not work properly, check the brake
booster. Replace the brake booster as an assembly ifit does not work properly or if there are signs of leak-
age.
@-Piston Cup and Pressure Cup Inspection. Check brake operation by applying the brakes.
Visually check for damage or signs of tluid leakage.Replace the master cylinder as an assembly if thepedal does not work properly or if there is damage orsigns of fluid leakage.
. Check for a difference in brake pedal stroke betweenquick and slow brake applications. Replace the mas-.
ter cylinder if there is a difference in pedal stroke.
(9-Brake Hoses
Visually check for damage or signs of fluid leakage.
Replace the brake hose with a new one if it is dam-
aged or leaking.
O-Caliper Piston S€al and Piston Boots
Check brake operation by applying the brakes.
Visually check for damage or signs of fluid leakage. lf
the pedal does not operate properly, the brakes drag,
or there is damage or signs of fluid leakage, disas-
semble and inspect the brake caliper. Replace the
boots and seals with new ones whenever the brake
caliper is disassembled.
@-Wheel Cylinder Piston Cup and Dust Cover
Check brake operation by applying the brakes.
Visually check for damage or signs of fluid leakage. lf
the pedal does not operate properly, the brakes drag,
or there is damage or signs of fluid leakage, replace
the wheel cvlinder.

Brake Pedal
Pedal Hoight
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. Lift up the carpet, At the insulator cutout, measure
the pedal height from the middle of the right side of
the oedal pad.
BRAKE SWITCH
ERAKE SWITCH
Standard Pedal Height (with floor m8i removed):
A/T: 161 mm (5 5/16 in)
M/T: 155 mm {6 U8 in}
Loosen the pushrod locknut, and screw the pushrod
in or out with pliers until the standard pedal height
from the floor is reached. Do not adjust the pedal
height with the pushrod pressed. After adiustment,
tighten the locknut firmly.
PUSHROD LOCKNUT
15 N.m11.5 kgj m, 11 lbf ftl
4. Screw in the brake switch until its plunger is fully
pressed (threaded end touching the pad on the
pedal arm), Then back otf 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 connecto.. Make sure that
the brake lights 90 off when the pedal is released
5. Checkthe brake pedalfree play as described below
Pedal Free Play
1. With the engine off. inspect the free play on the
pedal pad by pushing the pedal by hand-
Free Play: 1 - 5 mm (1/16 - 3/16 in)
2. lf the pedal free play is out of specification, adiust
the brake switch. lf the pedal free play is insuffi-
cient, it may result in brake drag.

Bleeding
CAUNON:
. Do not spill brake tluid on the vehicle. it may damage
the paint; if brake fluid does contaqt th€ paint, wash
it otf immodiately with water.
. Maks sure no dirt oy other forsign matter is allowsd
to contaminate the brake fluid.
NOTE:
. Do not reuse the drained fluid.
. Always use Genuine Honda DOT 3 Brake Fluid. Using
a non-Honda brake fluid can cause corrosion and
decrease the life of the svstem.
. The reservoir on the master cylinder must be at the
MAX (upper) level mark at the start of bleeding pro-
cedure and checked after bleeding each brake caliper
and wheel cylinder. Add fluid as required.
1, Make sure the brake fluid level in the reservoir is at
the MAX (uDDer) level line.

Have someone slowly pump the brake pedal several
times, then apply steady pressu.e.
Loosen the brake bleed screw to allow air to escape
from the system. Then tighten the bleed screw
securely.
Repeat the procedure for each wheel in the sequence
shown below until air bubbles no longer appear in
the tluid.
Refill the reservoir on the master cvlinder to the
MAX (upper) level line.
