CUSTOMIZE LUGGAGE COMPARTMENT DOOR OPENER SYSTEM
HINT:
The following items can be customized.
NOTICE:
- When the customer requests a change in a function, first make sure that the function can be customized.
- Be sure to make a note of the current settings before customizing.
- When troubleshooting a function, first make sure that the function is set to the default setting.
(a) Customizing with the Techstream
(1) Connect the Techstream to the DLC3.
(2) Turn the engine switch on (IG).
(3) Turn the Techstream on.
(4) Enter the following menus: Customize Setting / Door Lock.
(5) Select the setting by referring to the table below.

DATA LIST
NOTICE:
In
the table below, the values listed under "Normal Condition" are
reference values. Do not depend solely on these reference values when
deciding whether a part is faulty or not.
HINT:
Using
the Techstream to read the Data List allows the values or states of
switches, sensors, actuators and other items to be read without removing
any parts. This non-intrusive inspection can be very useful because
intermittent conditions or signals may be discovered before parts or
wiring is disturbed. Reading the Data List information early in
troubleshooting is one way to save diagnostic time.
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / (desired system) / Data List.
(e) Read the Data List according to the display on the Techstream.

ACTIVE TEST
HINT:
Using
the Techstream to perform the Active Tests allows relays, VSVs and
actuators and other items to be operated without removing any parts.
This non-intrusive functional inspection can be very useful because
intermittent operation may be discovered before parts or wiring is
disturbed. Performing Active Tests early in troubleshooting is one way
to save diagnostic time. Data List information can be displayed while
performing Active Tests.
(a) Connect the Techstream to the DLC3.

CUSTOMER PROBLEM ANALYSIS |
HINT:
- In troubleshooting, confirm that the problem symptoms have been
accurately identified. Preconceptions should be discarded in order to
make an accurate judgment. To clearly understand what the problem
symptoms are, it is extremely important to ask the customer about the
problem and the conditions at the time the malfunction occurred.
- Gather as much information as possible for reference. Past problems that seem unrelated may also help in some cases.
- The following 5 items are important points for problem analysis:
|
What |
Vehicle model, system name |
|
When |
Date, time, occurrence frequency |
|
Where |
Road conditions |
|
Under what conditions? |
Driving conditions, weather conditions |
|

Standard Voltage:
11 to 14 V
If the voltage is below 11 V, recharge or replace the battery before proceeding to the next step.
(b) Check the fuses and relays.
(c)
Check the connector connections and terminals to make sure that there
are no abnormalities such as loose connections, deformation, etc.
