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.
Recomm6nded Engine OilEngine oil viscosity for ambient temperature ranges
100'F
-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.

Starting System
Starter Test
NOTE: The air temperature must be between 59 and'100'F (15 and 38"C) before testing.
Recommended Procedure:
. Use a staner system tester.
. Connect and operate the equipment in accordance
with the manufacturer's instructions.
. Test and troubleshoot as described.
Alte.nate Procedure:
. Use the following equipment:- Ammeter, 0 - 400 A- Voltmeter, 0 - 20 V (accurate within 0.1 volt)
Tachometer,0 - 1,200 rpm
. Hook up a voltmeter and ammeter as shown.
NOTE: After this test, or any subsequent repair. reset
the ECM/PCM to clear any codes (see section 1 1).
Check the Starter Engagement:
'1. Remove the No. 44 (15 A) fuse from the under-hood
fuse/relay box.
2. Turn the ignition switch to START (lll) with the shift
lever in E or E position (A/T) or with the clutch
pedal depressed {M/T). The starter should crank the
eng ine.
. lf the starter does not crank the engine, go to
step 3.
. lf it cranks the engine erratically or too slowly, go
to "Check for Wear and Damage" on the next
page.

Check the battery, battery positive cable, ground.
staner cut relay, and the wire connections for loose-
ness and corrosion. Test again.
lf the staner still does not crank the engine, go to
step 4.
Unplug the connector (BLK /VHT wire and solenoid
terminal) from the starter.
Connect a jumper wire from the baftery positive (+)
terminal to the solenoid terminal.
The starter should crank the engine.
. lf the starter still does not crank the engine,
remove it, and diagnose its internal problem.
. lf the starter cranks the engine, go to step 6.
Check the ignition switch (see section 23).
Check the starter cut relay {see section 23}.
Check the IVT gear position switch (A/T) or the clutch
interlock switch (M[).
Check for an open in the wire between the ignition
switch and starter.

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.
