Lubrication Points
For the details of lubrication points and type of lubricants to be applied. refer to the illustrated index and various work pro-
cedures (such as Assembly/Reassembly, Replacement, Overhaul, Installation, etc.) contained in each section.

-30 -20 .10 0 10 20 30 40'c
r1: Always use Genuine Honda Manual Transmission Fluid {MTF). Using motor oil can cause stiffer shifting because it
does not contain the orooer additives.*2: Always use Genuine Honda Premium Formula Automatic Transmission Fluid (ATF). Using a non-Honda ATF can affect
shift qualitv.+3r Always use Genuine Honda DOT 3 Brake Fluid. Using a non-Honda brake fluid can cause corrosion and decrease the
life of the system.*4: Always use Genuine Honda Power Steering Fluid. Using any other type of power steering fluid or automatic transmis-
sion fluid can caused increased wear and poor steering in cold weather.

PGM-Fl System
The PGM-Fl system on this model is a sequential multiport fuel injection system.
Fuel iniecior Timing and Duration
The ECM/PCM contains memories for the basic discharge durations at various engine speeds and manifold pressure. The
basic discharge duration, after being read out from the memory, is further modified by signals sent from various sensors
to obtain the final discharge duration.
ldle Air Control
ldle Air Control Valve (lAC Valve)
When the engine is cold, the Ay'C compressor is on, the transmission is in gear, the brake pedal is depressed, the P/S load
is high, or the alternator is charging, the ECM/PCM controls current to the IAC Valve to maintain the correct idle speed.
lgnition Timing Control
o The ECM/PCM contains memories for basic ionition timing at various engine speeds and manifold air flow rates.
lgnition timing is also adjusted for engine coolant temperature.
. A knock control system was adopted which sets the ideal ig nition timing for the octane rating of the gasoline used.*s
Other Control Funstions
1. Starting Control
When the engine is started. the ECM/PCM provides a rich mixture by increasing fuel injector duration.
2. Fuel Pump Control
. When the ignition switch is initially turned on (ll). the ECMiPCM suppli€s ground to the PGM-FI main relay that
supplies current to the fuel pump for two seconds to pressurize the fuel system.
. When the engine is running, the ECM/PCM supplies ground to the PGM-FI main relay that supplies current to the
fuel oumo.
. When the engine is not running and the ignition is on, the ECM/PCM cuts ground to the PGM-FI main relay which
cuts current to the fuel pump.

CAUTION:
. Do not spill brake fluid on the vehicle; it may damage
the paint; if brake tluid does contact the paint. wash
it off immediately with water.
. Plug the end ol the clutch line and leservoir hose
with a shop towel to prevent brake tluid trom coming
out.
The brake fluid may be sucked out through the top
of the master cylinder reservoir with a syringe.
Disconnect the clutch line and reservoir hose from

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

Front Brake Caliper
Disassembly/Reassembly
. Never use an air hose or dry brush to clean brake assemblies.
. Use an OSHA approved vacuum cleaner to avoid breathing brake dust.
. Contaminated brake discs or pads reduce stopping ability.
. When reusing the pads, always reinstallthe brake pads in their original positions to prevent loss ol braking efficiency.
CAUTION:
. Do not spill brake fluid on the vehicle; it may damage the paint; if brake fluid does contact the paint, wash it off imme-
diatelY with water.
NOTEI
. To prevent spills, cover the hose joints with rags or shop towels.
. Clean all pans in brake fluid and air dry; blow out all passages with compressed air.
. Before reassembling, check that all parts are free of dust and other foreign particles.
. Replace parts with new ones whenever specified to do so.
. Make sure no dirt or other foreign matter is allowed to contaminate the brake fluid.
. 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 system.
. Coat the piston, piston seal, and caliper bore with clean brake fluid.
. ReDlace all rubber oarts with new ones whenever disassembled.
. After installing the front brake caliper do the following.- Check for leaks at hose and line joints and connections, and retighten if necessary.- Check the brake hoses for interference and twistinq.
