Body Front End
lWhen removing or installing hood, place a cloth or other padding on the front fender panels and cowl
top. This prevents vehicle body from being scratched.
lBumper fascia is made of plastic. Do not use excessive force and be sure to keep oil away from it.
lHood adjustment: Adjust at hinge portion.
lHood lock adjustment: After adjusting, check hood lock control operation. Apply a coat of grease to hood
locks engaging mechanism.
lHood opener: Do not attempt to bend cable forcibly. Doing so increases effort required to unlock hood.

Precautions
lBefore connecting or disconnecting the ECM harness
connector, turn ignition switch OFF and disconnect
negative battery terminal. Failure to do so may damage
the ECM because battery voltage is applied to ECM even
if ignition switch is turned off.
lWhen connecting ECM harness connectors, push in
both sides of the connector until you hear a click.
Maneuver the lever until you hear the three connectors
on the inside click. Refer to the figure at left.
lBefore replacing ECM, perform Terminals and Reference
Value inspection and make sure ECM functions properly.
Refer to EC-CD-52.
lIf MI illuminates or blinks irregularly during engine
running, water may have accumulated in fuel filter. Drain
water from fuel filter. If this does not correct the problem,
perform specified trouble diagnostic procedures.
lAfter performing each TROUBLE DIAGNOSIS, perform
ªOVERALL FUNCTION CHECKº or ªDTC (Diagnostic
Trouble Code) CONFIRMATION PROCEDUREº.
The DTC should not be displayed in the ªDTC CONFIR-
MATION PROCEDUREº if the repair is completed. The
ªOVERALL FUNCTION CHECKº should be a good result
if the repair is completed.

CONSULT-II (Cont'd)
EC-31

Introduction
The engine has an ECM to control major systems such as fuel
injection control, fuel injection timing control, glow control
system, etc. The ECM accepts input signals from sensors and
instantly drive the electronic fuel injection pump use the data to
based on current ambient conditions. It is essential that both
input and output signals are correct and stable. At the same time,
it is important that there are no problems such as vacuum leaks,
or other problems with the engine.
It is much more difficult to diagnose a problem that occurs inter-
mittently rather than catastrophically. Most intermittent problems
are caused by poor electric connections or faulty wiring. In this
case, careful checking of suspected circuits may help prevent the
replacement of good parts.
A visual check only may not be sufficient to determine the cause
of the problems. A road test with CONSULT-II or a circuit tester
connected should be performed. Follow the ªWork Flowº on the
next page.
Before undertaking actual checks, take a few minutes to talk with
a customer who approaches with a driveability complaint. The
customer can supply good information about such problems,
especially intermittent ones. Find out what symptoms are present
and under what conditions they occur. A ªDiagnostic Worksheetº
like the example on next page should be used.
Start your diagnosis by looking for ªconventionalº problems first.
This will help troubleshoot driveability problems on a vehicle with
an electronically controlled engine.

TROUBLE DIAGNOSIS Ð IntroductionCD20T
EC-33

Description for Work Flow
STEP DESCRIPTION
STEP IGet detailed information about the conditions and the environment when the incident/symptom occurred
using the ªDIAGNOSTIC WORKSHEETº as shown on the previous page.
STEP IIBefore confirming the concern, check and write down (print out using CONSULT-II) the malfunction item,
then erase the code. The malfunction item can be used when duplicating the incident at STEP III & IV.
Study the relationship between the cause, specified by malfunction item, and the symptom described by the
customer. (The ªSymptom Matrix Chartº will be useful. Refer to EC-CD-47.)
STEP IIITry to confirm the symptom and under what conditions the incident occurs.
The ªDIAGNOSTIC WORK SHEETº is useful to verify the incident. Connect CONSULT-II to the vehicle in
DATA MONITOR (AUTO TRIG) mode and check real time diagnosis results.
If the incident cannot be verified, perform INCIDENT SIMULATION TESTS. Refer to GI section.
If the malfunction code is detected, skip STEP IV and perform STEP V.
STEP IVTry to detect the malfunction item by driving in (or performing) the ªDIAGNOSTIC TROUBLE CONFIRMA-
TION PROCEDUREº. Check and read the malfunction item by using CONSULT-II.
During the malfunction item verification, be sure to connect CONSULT-II to the vehicle in DATA MONITOR
(AUTO TRIG) mode and check real time diagnosis results.
If the incident cannot be verified, perform INCIDENT SIMULATION TESTS. Refer to GI section.
In case the ªDIAGNOSTIC TROUBLE CONFIRMATION PROCEDUREº is not available, perform the ªOVER-
ALL FUNCTION CHECKº instead. The malfunction item cannot be displayed by this check, however, this
simplified ªcheckº is an effective alternative.
The ªNGº result of the ªOVERALL FUNCTION CHECKº is the same as the DTC detection.
STEP VTake the appropriate action based on the results of STEP I through IV.
If the malfunction code is indicated, proceed to specific TROUBLE DIAGNOSIS for the malfunction item.
If the normal code is indicated, proceed to the BASIC INSPECTION. Refer to EC-CD-37. Then perform
inspections according to the Symptom Matrix Chart. Refer to EC-CD-47.
STEP VIIdentify where to begin diagnosis based on the relationship study between symptom and possible causes.
Inspect the system for mechanical binding, loose connectors or wiring damage using (tracing) ªHarness Lay-
outsº.
Gently shake the related connectors, components or wiring harness with CONSULT-II set in ªDATA MONI-
TOR (AUTO TRIG)º mode.
Check the voltage of the related ECM terminals or monitor the output data from the related sensors with
CONSULT-II. Refer to EC-CD-52.
The ªDIAGNOSTIC PROCEDUREº in EC section contains a description based on open circuit inspection. A
short circuit inspection is also required for the circuit check in the DIAGNOSTIC PROCEDURE. For details,
refer to GI section (ªCircuit Inspectionº, ªHOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRI-
CAL INCIDENTº).
Repair or replace the malfunctioning parts.
STEP VIIOnce you have repaired the circuit or replaced a component, you need to run the engine in the same condi-
tions and circumstances which resulted in the customer's initial complaint.
Perform the ªDIAGNOSTIC TROUBLE CONFIRMATION PROCEDUREº and confirm the normal code is
detected. If the incident is still detected in the final check, perform STEP VI by using a different method from
the previous one.
Before returning the vehicle to the customer, be sure to erase the unnecessary (already fixed) malfunction
item in ECM.

Basic Inspection
Precaution:
Perform Basic Inspection without electrical or mechanical
loads applied;
lHeadlamp switch is off,
lAir Conditioner switch is off,
lRear defogger switch is off,
lSteering wheel is in the straight-ahead position, etc.
BEFORE STARTING
1. Check service records for any
recent repairs that may indicate a
related problem, or the current need
for scheduled maintenance.
2. Open engine hood and check the
following:
lHarness connectors for faulty con-
nections
lVacuum hoses for splits, kinks, or
faulty connections
lWiring for faulty connections,
pinches, or cuts
3. Using priming pump, bleed air from
fuel system. Refer to ªFuel Filter
Checkº in MA section.
CONNECT CONSULT-II TO THE
VEHICLE.
Connect ªCONSULT-IIº to the data link
connector for CONSULT-II and select
ªENGINEº from the menu. Refer to EC-
CD-27.
DOES ENGINE START?
Ye s
ENo
Turn ignition switch to
the ªLOCKº position, wait
5 seconds and then start
engine. If engine fails to
start, check malfunction
item.
Run engine for 10 minutes.
CHECK IDLE SPEED.
Read engine idle speed in
ªDATA MONITORº mode with
CONSULT-II.
825 rpm   25 (in N position)
