r(For the details of lubrication points and type of lubricants to be applied, refer to the illustrated index and various work Dro-cedure (such as Assembly/Reassembly, Replacement, Overhaul, Installation. etc.) contained in each section,
*1: Always use Genuine Honda Manual Transmission Fluid (MTF). Using motor oil can cause stiffer shifting because itdoes not contain the proper addtuves.*2: Always use Genuine Honda Premium Formula Automatic Transmission Fluid (ATF). Using a non-Honda ATF can affectshift quality.*3: Always use Genuine Honda DOT 3 B.ake Fluid, Using a non-Honda brake fluid can cause corrosion and decrease thelife of the system.'4: Always use Genuine Honda Power Steering Fluid-V or S. Using any other type of power steering fluid or automatictransmission fluid can cause increase v,/ear and poor steering in cold weather.

Engine Removal/lnstallation
2. Remove the strut brace.
Make sure iacks and safety stands ate placed plopel-
ly and hoist brackets are attached to the correct po-
sitions on the engine {see section 11,
Make sure the car will not rollolt stands and latl whileyou are wgrking under it.
8 x 1.25 mm24 N.m {2.4 kgf.m,17 tbf.tt)
CAUTION:
. Use fender covers to avoid damaging painted sur-
faces.
Unplug the wiring connectors carelully while holding
the coupler and the connector portion to avoid d8m-
age.
Mark all wiring and hoses to avoid misconnection.
Also. be sure that they do not contact other wiring
or hoses, or intedere with other parts.
NOTE: Anti-theft radios have a coded theft protection cir-
cuit. Be sure to get the customer's code number betore- Disconnecting the battery.- Removing the No.32 (7.5 A) fuse from the under
hood fuse/relay box.
Removing the radio
After service, reconnect power to the radio and turn it
on. When the word "CODE" is displayed, enter the cus
tomer's 5-digit code to restore radio operation.
1. Remove the hood (see section 20).
3.Disconnect the battery negative terminal first, then
the positive terminal.
Disconnect the battery cables Irom the under-hood
Iuse/relay box and under hood ABS {use/relay box.

PGM-FI System
System Description
ENGINE CONTROL MODULE (ECM)OUTPUTS
*1: USA*2: 818C1 engine*3: A,/T*4: 818C1, 818C5 engines
PGM-FI Sy3tem
The PGM-Fl system on this model is a sequential multiport fuel injection system.
Fuel lniector Timing and Duration
The ECM contains memories for the basic discharge durations at various engine speeds and manifold pressures. 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 Ai. Control Valve (lAC Valve)
When the engine is cold, the Ay'C compressor is on. the transmission is in gear (Ay'T only)the brake pedal is depressed, the
P/S load is high, or the alternator is charging, the ECM controls current to the IAC Valve to maintain correct idle speed.
lgnition Timing Control
. The ECM contains memories for basic ignition timing atvarious engine speeds and manifold pressures, lgnitiontiming
is also adjusted for engine coolant temperature.
. AKnockControl System isadoptedwhich sets the ideal ignition timing for the octane n um ber of gasoline used*r,
Other Control Functions
L Starting Control
When the engine is started, the ECM provides a rich mi{ure by increasing fuel injector duration.
2. Fuel PumD Control
. When the ignition switch is initially turned on, the ECM supplies 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 supplies ground to the PGM-FI main relay that supplies current to the fuel
DUmO.
. When the engine is not running and the ignition is on. the ECM cuts ground to the PGM-FI main relay which cuts
current to the fuel oumo.
