BASIC TROUBLESHOOTING GUIDE

Bring Vehicle to Workshop

Perform troubleshooting procedure for DTC

Adjust or repair the vehicle

Confirmation test

END

Analyze Customer’s Problem

Ask the customer about the conditions and environment relative to the issue
(Use CUSTOMER PROBLEM ANALYSIS SHEET).

Confirm the Inspection Procedure for the System or Part

Using the SYMPTOM TROUBLESHOOTING GUIDE CHART, choose the correct inspection procedure for the system
or part to be checked.

Inspect Vehicle Visually

Go to Step 11, if you recognize the problem.

Recreate (Simulate) Symptoms of the DTC

Try to recreate or simulate the symptoms and conditions of the malfunction as described by customer.
If DTC(s) is/are displayed, simulate the condition according to troubleshooting procedure for the DTC.

Recreate (Simulate) Symptom

Try to recreate or simulate the condition of the malfunction as described by the customer.

Check the DTC

If DTC(s) does(do) not occur, refer to INTERMITTENT PROBLEM PROCEDURE in BASIC INSPECTION PROCEDURE.
If DTC(s) occur(s), go to Step 11.

Confirm Symptoms of Problem

If DTC(s) is/are not displayed, go to Step 9.
If DTC(s) is/are displayed, go to Step 11.

Verify Symptom, and then Check DTC and Freeze Frame Data

Connect Hi-Scan (Pro) to Diagnostic Link Connector (DLC).
Record the DTC and freeze frame data.

To erase DTC and freeze frame data, refer to Step 5.

Erase the DTC and Freeze Frame Data

NEVER erase DTC and freeze frame data before completing Step 2 MIL/DTC in "CUSTOMER PROBLEM
ANALYSIS SHEET".

FUEL SYSTEM

BASIC INSPECTION PROCEDURE

MEASURING CONDITION OF ELECTRONIC PARTS’
RESISTANCE

The measured resistance at high temperature after vehi-
cle running may be high or low. So all resistance must
be measured at ambient temperature (20

℃

, 68

℉

), unless

stated otherwise.

NOTE

The measured resistance in except for ambient tem-
perature (20

℃

, 68

℉

) is reference value.

INTERMITTENT PROBLEM INSPECTION
PROCEDURE

Sometimes the most difficult case in troubleshooting is
when a problem symptom occurs but does not occur again
during testing. An example would be if a problem appears
only when the vehicle is cold but has not appeared when
warm. In this case, the technician should thoroughly make
out a "CUSTOMER PROBLEM ANALYSIS SHEET" and
recreate (simulate) the environment and condition which
occurred when the vehicle was having the issue.

Clear Diagnostic Trouble Code (DTC).

Inspect connector connection, and check terminal for
poor connections, loose wires, bent, broken or cor-
roded pins, and then verify that the connectors are
always securely fastened.

BFGE321A

Slightly shake the connector and wiring harness ver-
tically and horizontally.

Repair or replace the component that has a problem.

Verify that the problem has disappeared with the road
test.

●

SIMULATING VIBRATION

Sensors and Actuators
: Slightly vibrate sensors, actuators or relays with fin-
ger.

WARNING

Strong vibration may break sensors, actuators or
relays

Connectors and Harness
: Lightly shake the connector and wiring harness ver-
tically and then horizontally.

●

SIMULATING HEAT

Heat components suspected of causing the malfunc-
tion with a hair dryer or other heat source.

WARNING

• DO NOT heat components to the point where

they may be damaged.

• DO NOT heat the ECM directly.

●

SIMULATING WATER SPRINKLING

Sprinkle water onto vehicle to simulate a rainy day or
a high humidity condition.

WARNING

DO NOT sprinkle water directly into the engine
compartment or electronic components.

●

SIMULATING ELECTRICAL LOAD

Turn on all electrical systems to simulate excessive
electrical loads (Radios, fans, lights, rear window de-
fogger, etc.).

GENERAL

CONNECTOR INSPECTION PROCEDURE

Handling of Connector
a.

Never pull on the wiring harness when discon-
necting connectors.

BFGE015F

When removing the connector with a lock, press
or pull locking lever.

BFGE015G

Listen for a click when locking connectors. This
sound indicates that they are securely locked.

"CLICK"

BFGE015H

When a tester is used to check for continuity, or to
measure voltage, always insert tester probe from
wire harness side.

BFGE015I

Check waterproof connector terminals from the
connector side. Waterproof connectors cannot
be accessed from harness side.
