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.
1.
Clear Diagnostic Trouble Code (DTC).
2.
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
3.
Slightly shake the connector and wiring harness ver-
tically and horizontally.
4.
Repair or replace the component that has a problem.
5.
Verify that the problem has disappeared with the road
test.
●
SIMULATING VIBRATION
a.
Sensors and Actuators
: Slightly vibrate sensors, actuators or relays with fin-
ger.
WARNING
Strong vibration may break sensors, actuators or
relays
b.
Connectors and Harness
: Lightly shake the connector and wiring harness ver-
tically and then horizontally.
●
SIMULATING HEAT
a.
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
a.
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
a.
Turn on all electrical systems to simulate excessive
electrical loads (Radios, fans, lights, rear window de-
fogger, etc.).

CONNECTOR INSPECTION PROCEDURE
1.
Handling of Connector
a.
Never pull on the wiring harness when discon-
necting connectors.
BFGE015F
b.
When removing the connector with a lock, press
or pull locking lever.
BFGE015G
c.
Listen for a click when locking connectors. This
sound indicates that they are securely locked.
"CLICK"
BFGE015H
d.
When a tester is used to check for continuity, or to
measure voltage, always insert tester probe from
wire harness side.
BFGE015I
e.
Check waterproof connector terminals from the
connector side. Waterproof connectors cannot
be accessed from harness side.
