KEYLESS ENTRY SYSTEM
GENERAL DESCRIPTIONBGBJABIE
Antenna and receiver are incorporated in the
ETACS-ECU.
ID code can be registered by using Diagnostic
tool (MUT-III).
Transmitter is a key holder type, which incorpo-
rates lock button, unlock button, trunk button and
panic button .
When the transmitter unlock button is pressed
once, the driver's door will be unlocked. If the but-
ton is pressed twice, all the doors will be
unlocked. The adjustment function also allows
you to open all the doors by pressing the unlock
button only once. For further details on using the
multi-center display to adjust the unlock opera-
tion, refer to GROUP 54B, On-vehicle Service
P.54B-486.
When the transmitter is operated, the answer-
back function will work as follows:
The answerback operation can be altered as fol-
lows:NOTE: Enabling/disabling the hazard warning
light flashing, the horn sounding in accordance
with the answerback function. For further details
on using the transmitter to adjust answerback,

BASIC BRAKE SYSTEM DIAGNOSIS
INTRODUCTION TO BASIC BRAKE SYSTEM DIAGNOSISM1351009700319
Hydraulic brakes are composed of the brake pedal,
master cylinder, brake booster and disc brakes. Mal-
functions such as insufficient braking power or the
generation of noise may occur due to wear, damage
or incorrect adjustment of these components.
BASIC BRAKE SYSTEM DIAGNOSTIC TROUBLESHOOTING STRATEGYM1351009800316
Use these steps to plan your diagnostic strategy. If
you follow them carefully, you will be sure that you
have exhausted most of the possible ways to find a
basic brake system fault.
1. Gather information from the customer.2. Verify that the condition described by the
customer exists.
3. Find the malfunction by following the symptom
chart.
4. Verify malfunction is eliminated.

TROUBLESHOOTING GUIDELINESM1001008800340
VERIFY THE COMPLAINT
Make sure the customer's complaint and the ser-
vice writer's work order description are under-
stood before starting work.
Make sure you understand the correct operation
of the system. Read the service manual descrip-
tion to verify normal system operation.
Operate the system to see the symptoms. Look
for other symptoms that were not reported by the
customer, or on the work order, that may be
related to the problem.
DETERMINE POSSIBLE CAUSES
Compare the confirmed symptoms to the diagnostic
symptom indexes to find the right diagnosis proce-
dure.
If the confirmed symptoms cannot be found on any
symptom index, determine other possible causes.
Analyze the system diagrams and list all possible
causes for the problem symptoms.
Rank all these possible causes in order of proba-
bility, based on how much of the system they
cover, how likely they are to be the cause, and
how easy they will be to check. Be sure to take
experience into account. Consider the causes of
similar problems seen in the past. The list of
causes should be ranked in order from general to
specific, from most-likely to least-likely, and from
easy-to-check to hard-to-check.
FIND THE PROBLEM
After the symptoms have been confirmed, and prob-
able causes have been identified, the next step is to
make step-by-step checks of the suspected system
components, junctions, and links in logical order.
Use the diagnostic procedures in the service manual
whenever possible. Follow these procedures care-
fully to avoid missing an important step in the diagno-
sis sequence. It might be the skipped step that leads
to the solution of the problem.
If the service manual doesn't have step-by-step pro-
cedures to help diagnose the problem, make a series
of checks based on the ranked list of probable
causes. Troubleshooting checks should be made in
the order that the list of causes was ranked:
general to specific
most-likely to least-likely
easy-to-check to hard-to-check
REPAIR THE PROBLEM
When the step-by-step troubleshooting checks find a
fault, perform the proper repairs. Make sure to fix the
root cause of the problem, not just the symptom. Just
fixing the symptom, without fixing the root cause, will
cause the symptom to eventually return.
VERIFY THE REPAIR
After repairs are made, recheck the operation of the
system to confirm that the problem is eliminated. Be
sure to check the system thoroughly. Sometimes
new problems are revealed after repairs have been
made.

POINTS
TROUBLESHOOTING CONTENTSM1001013300062
During diagnosis, a DTC code associated with
other system may be set when the ignition
switch is turned on with connector(s) discon-
nected. On completion, confirm all systems
for DTC code(s). If DTC code(s) are set, erase
them all.
When the DIAGNOSTIC TOOL (MUT-III)
detects a diagnostic trouble code, its display
informs users whether a mechanical problem
currently exists (“current trouble”) or whether
it existed before but normal operation has
been restored (“past trouble”). However, if an
MPI, TPMS or SRS airbag-related DTC is set,
“Active DTC/Stored DTC” is not displayed. In
this case, follow the diagnosis procedure for
current trouble.
If a trouble, detected in a CAN communica-
tion-capable system, can be reproduced,
diagnose the CAN bus lines (Refer to GROUP
54C, Can Bus Line Diagnostics Chart
P.54C-15 or P.54C-15).
Troubleshooting of electronic control systems for
which the MUT -III can be used follows the basic out-
line described below. Even in systems for which the
MUT-III cannot be used, part of these systems still
follow this outline.

the applicable inspection procedure according to this
chart.
5. SYMPTOM CHART
If there are symptoms, even though the MUT-III
shows that no DTCs are set, inspection procedures
for each symptom will be found by using this chart.
6. DIAGNOSTIC TROUBLE CODE
PROCEDURES
Indicates the inspection procedures corresponding to
each diagnostic trouble code. (Refer to P.00-9).
7. SYMPTOM PROCEDURES
Indicates the inspection procedures corresponding to
each symptom listed in the Symptom Chart (Refer to
P.00-9).
8. SERVICE DATA REFERENCE TABLE
Inspection items and normal judgment values have
been provided in this chart as reference information.
9. CHECK AT ECU TERMINALS
Terminal numbers for the ECU connectors, inspec-
tion items, and standard values have been provided
in this chart as reference information.
.
TERMINAL VOLTAGE CHECKS
1. Use correct tool to check each pin location on the
ENGINE-ECU Check harnes MB992044 and
measure with voltmeter.
Short-circuiting the positive (+) test probe
between a connector terminal and ground could
damage the vehicle wiring, the sensor, the ECU,
or all three. Use care to prevent this!
2. Insert the correct terminal tool into each of the
ENGINE-ECU check harness connector
terminals, and measure the voltage while referring
to the check chart.
NOTE: Measure voltage with the ECU connectors
connected.
You may find it convenient to pull out the ECU to
make it easier to connect the ENGINE-ECU check
harness.

HOW TO COPE WITH INTERMITTENT
MALFUNCTIONS
M1001013900064
Most intermittent malfunctions occur under certain conditions. If
those conditions can be identified, the cause will be easier to
find.
.
TO COPE WITH INTERMITTENT MALFUNCTION;
1. ASK THE CUSTOMER ABOUT THE
MALFUNCTION
Ask what it feels like, what it sounds like, etc. Then ask about
driving conditions, weather, frequency of occurrence, and so
on.
.
2. DETERMINE THE CONDITIONS FROM THE
CUSTOMER'S RESPONSES
Typically, almost all intermittent malfunctions occur from condi-
tions like vibration, temperature and/or moisture change, poor
connections. From the customer's responses, it should be rea-
soned which condition is most likely.
.
3. USE SIMULATION TEST
Use the simulation tests below to attempt to duplicate the cus-
tomer's complaint. Determine the most likely circuit(s) and per-
form the simulation tests on the connectors and parts of that
circuit(s). Be sure to use the inspection procedures provided for
diagnostic trouble codes and trouble symptoms.
For temperature and/or moisture condition related intermittent
malfunctions, try to change the conditions of the suspected cir-
cuit components, then use the simulation tests below.
.
